1 INTRODUCTION
The Series 2000 and Series 2000-SAN are solid-state pressure- and level transmitters based upon a bridge
resistive silicon sensor, with a very high burst pressure. The sensor element is mounted in a stainless steel
foot. A very strong stainless steel "flush" diaphragm protects the sensor from the process medium. Special
oil fills the chamber surrounding the sensor and transfers pressure from the flush mounted diaphragm to the
sensor.
Pressure on the sensor element creates a very small deflection of the silicon substrate and bridge network.
The resulting strain in the silicon resistors causes a change in the bridge resistance proportional to the
pressure applied. The transmitter electronics detects this change in bridge resistance and converts it into
4-20 mA. The amplifier system is based on a single Integrated Circuit, which ensures a perfect linearity in the
4-20 mA output. Together with the Klay flush diaphragm technology the long term stability is perfect.
The Series CER-2000 are "All Stainless Steel" pressure transmitters based on a ceramic pressure cell, with
very high burst pressure. These transmitters do not have oil filling.
The Series 2000, 2000-SAN and CER 2000 are available as SIL2, proven in use (Option G200).
1.1 DESCRIPTION SERIES 2000-SAN
The Series 2000-SAN are specially designed with a flush mounted diaphragm so they fully meet the needs
of the food, pharma and chemical industries. The Series 2000-SAN is available as 3-A version (Sanitary
Standard - Option G153) and EHEDG (Sanitary standard –Option G150). Standard the wetted parts are
made of AISI 316, other materials are available, like Hastelloy C. Various process connections can be
delivered, such as Tri-Clamp (1.5”, 2” and 3”), SMS (1.5” and 2”), dairy milk couplings (DN 25, 40 and 50),
flanges (DIN and ANSI) and sanitary weld-on adaptors (ø 1.89, 2.44 and 3.34 inch)
1.2 DESCRIPTION SERIES 2000
The Series 2000 is specially designed for the pulp and paper or similar industries, where clogging is a
problem. The very compact construction of the Series 2000 permits flush installation with the tank or pipe
wall. Standard the wetted parts are made of AISI 316, a lot of other materials are available.
All transmitters are fully temperature compensated, which means that various process temperatures have
nearly no effect on the accuracy of the output signal. When a failure occurs, the transmitter is repairable.
However, for optimum accuracy the transmitter has to be send back to the factory.
1.3 DESCRIPTION PERAMIC "S" (SERIES CER-2000)
The Series CER-2000 is a pressure transmitters based on a ceramic pressure cell, which can be used for
all gauge and absolute pressure measurement on steam, liquids and gases. These transmitters do not
have oil filling.
1.4 DESCRIPTION (SERIES 2000-HYDROBAR)
The Series 2000-Hydrobar is a complete range of submersible level transmitter for top mounting. The 2000-
Hydrobar can be used in fluids like waste water, mud, pulp and chemicals. As standard the cable material is
polyethylene. The connections for the wetted parts from the 2000-Hydrobar to the cable are from Viton® FKM.
1.5 BAROMETRIC REFERENCE
The Series 2000 is in basic a so called Relative Transmitter which means that barometric changes will not
affect the zero (4 mA). The venting (4) is placed in the cover of the housing and is the barometric reference
to atmospheric pressure. The venting must be kept clean.

3 INSTALLING TRANSMITTER
The diaphragm of the transmitter is protected with a special protection cap. Protect the diaphragm until
installation takes place. DO NOT DAMAGE THE DIAPHRAGM
3.1 INSTALLING WELD-ON ADAPTOR
A certified welder should perform installation of the weld-on adaptor.
Weld with Argon, MIG or TIG. The smallest welding pin should be used.
1. Cut a hole in the process vessel/pipe to accept the weld-on adaptor. The hole should produce a
tight fit when coupled with the weld-on adaptor.
2. Prepare the hole by beveling the edge to accept filler material.
3. Remove the weld-on Adaptor from the transmitter.
4. Remove the PTFE packing of the SERIES 2000-SAN.
5. Remove the gasket and O-Ring out of the weld-on adaptor!
WARNING
Improper installation may result in distortion of the weld-on adaptor.
Excessive heat will distort the weld-on adaptor. Weld in sections as
shown in the figure left. Allow adequate cooling between passes.
To reduce the chances of distortion to the weld-on adaptor,
use a mandrel.
Series 2000-SAN Part.no. 1019
Series 2000 Part.no. 1016
Determine (before welding) the position of the electronic housing, so
that the cable entry and the venting are in the right position. After
welding these positions are fixed.
6. Position the weld-on adaptor in the vessel hole and tack six places.
The weld sequence is shown in the figure above.
7. Weld the weld-on adaptor in place using 0.03 to 0.045 inch. (0.762 to 1.143 mm) stainless rod
as filler material in the beveled area. Adjust amperage for penetration.
8. Remove the mandrel after the welding operation.
3.2 INSTALLING TRANSMITTER SERIES 2000-SAN
1. Make sure to correctly locate the packing within the weld-on adaptor.
2. Improper installation of the packing can cause a process leak.
3. Position the transmitter into the weld-on adaptor and begin engaging threads.
4. The transmitter can be rotated prior to seating enabling the user to optimize access to
calibration adjustments, cable entry, and local indicator.
5. Once the Lock ring (9) has been hand tightened, it must be tightened with an additional turn
with adjustable pliers (± 1/8").
3.3 INSTALLING TRANSMITTER SERIES 2000
1. After welding, clean up edges, and take care of the inside adaptor wall.
2. Make sure the O-Ring (10) and (11) are properly located.
Improper installation at the O-Ring can cause a process leak.
3. Apply silicone grease to the O-Ring (10), diaphragm ring and the hole inside wall of the weld-on
adaptor, this prevents galvanic cell corrosion between transmitter and Adaptor inside.
4. Install the transmitter and fix it with the AISI M8 bolt.

3.4 INSTALLING TRANSMITTER SERIES CER-2000
The position of the electronic housing is depending on the welding position of the weld-on adaptor. Before
welding, locate the weld-on adaptor so that the cable entry and the venting are in the right direction.
DO NOT DAMAGE THE THREAD.
3.5 MOUNTING POSITION
When the transmitter is mounted horizontally, the cable gland must be pointed downwards.
3.6 MOUNTING POSITION EFFECT (Series 2000 and Series 2000-SAN)
All transmitters are calibrated in vertical position. If the transmitter is mounted in another position, there can
be a little zero shift. (4.02 mA instead of 4.00 mA). If the transmitter is mounted down, there is a zero shift
(For example 3.98 mA instead of 4.00 mA). After installation of the transmitter the zero must be set to 4.00
mA with P103 in the programming mode. This will not affect the span.
3.7 INSTALLING TRANSMITTER SERIES 2000-Hydrobar
The diaphragms are protected by a special protection cap (PE). Do not remove this cap. When clogging is a
problem, please contact Klay Instruments. Do not damage the diaphragm.
3.8 CALIBRATION
All transmitters are fully calibrated at the factory, to customer specified range. If calibration is not specified,
the transmitter will be calibrated at the maximum span.
3.9 WIRING
Under the cover (3) you will find the terminal board.
The push buttons "Zero", "Span" and "Prog" are
under the other cover (1). External loads must be
placed in the negative side of the 2-wire loop.
The figure left shows the wiring connection of the
transmitter. The 2-wires must be connected to 3 (-)
and 4 (+) of the terminal board.
The screw terminal tightening torque range needs to be: minimum 1.0 Nm (8.85 in-lb); max. 1,2 Nm
(10.62 in-lb).
Remove approx. 5 cm (2 in) of the cable mantle, strip approx. 1 cm (0.4 in) of insulation from the ends
of the individual wires. When using stranded cable apply the correct end sleeves for the wires and
make sure these are connected properly underneath the screw terminals.
The field wire conductor cross-section needs to be: minimum 0,2 mm2(24 AWG) and maximum 1,5
mm2(16 AWG). The transmitter must always be connected to
earth. The transmitter must be connected with
standard two-wire shielded cable. Do not run signal
wiring in open trays with power wiring, or near heavy
electrical equipment (Frequency controller or heavy
pumps). Shielding must always be connected at the
side of the power supply. In case the process
connection is already connected to ground (e.g. via
the tank or pipe line) Do not connect the instrument
to ground. Please ensure that the instrument is
not connected to ground twice to prevent an
'earth loop'. In applications with synthetic process
connections, the enclosure (internal or external)
must be connected to ground.
The CER-2000 with a synthetic process connection must be
connected to earth. Reversing the polarity will not damage the
transmitter, but the transmitter will not function
until the + and –are properly connected.

4.7 SOFTWARE REVISIONS
Due to the improvements on the Series 2000, there are several software versions (revisions).
For this reason it is possible the transmitter you are working with does not support some options,
which are discussed in this manual. This instruction is applicable from software version V9.17 and higher.
After powering up, the transmitter will show the software version on the display.
5 PUSH BUTTONS FUNCTIONS
The Series 2000 can be programmed easily by use of the 3 front
panel pushbuttons. The display can show engineering units of:
mH2O, inH2O, bar and PSI.
The functions of the three pushbuttons will be explained below.
This button has 2 functions:
It can be directly used for adjusting the zero (4 mA), with or without a test pressure.When
the zero (4 mA) must be adjusted at 0 (atmospheric pressure), the button must be held
until the word "Zero" appears on the display. The transmitter is now set to 4 mA.
This button must be used for stepping down in the menu or to decrease a value (-).
For canceling the mounting position effect you have to use P103.
This button has 2 functions:
It can be directly used for adjusting the span (20 mA), when using a test pressure (air).
When a test pressure (e.g. 2 bar) is supplied to the transmitter, the button must be held
until the word "SPAN" appears on the display. The transmitter is adjusted at 20 mA now.
The span can also be adjusted without test pressure (see P102).
This button must be used for stepping up in the menu or to increase a value (+).
This button has 2 functions:
It is used to adjust the Programming Points (P101 till P114). Push it once and P100 is
displayed, use the [] (SPAN) to step to P101.
This button must also be used for confirming the adjustments (enter).
For example, if you want to change the adjustment in psi (P104),
the following steps must be taken:
1. Push on [PROG] till "100" appears on the display.
2. Push on [SPAN] 4 times to go to point "P104" (adjustment pressure unit).
3. Push [PROG] to confirm this.
4. Push several times on [] (SPAN) to reach 3 (= bar). (Conversion table page 11).
5. 1 = mWC, 3 = bar, 5 = PSI, 11 = inch WC
6. Confirm this by pushing once at [PROG].
7. The transmitter is now adjusted to read in psi.

7. READING ON THE DISPLAY
On the standard built-in display several values can be
shown. When the transmitter is in the process the display
gives all the information of the process pressure or
temperature. On the display the following units are available:
mH2O, inH2O, bar and PSI (see P104 and P109).
The standard transmitter is supplied with two "closed" covers protecting the buttons and the display. As an option an "open" cover
(IP 66) can be fitted. The display can then be used as a local process display. (Option: "I" extra price). The full scale can be set
between -9999 and 9999 (4 digit).

8. EXPLANATION PROGRAMMING POINTS P101 to P114
ZERO ADJUSTMENT (4 mA)
The transmitter as standard is adjusted to 4.00 mA at atmospheric pressure.
It is also possible to adjust a zero-suppression or elevation.
For example: Zero elevation of 1.45 psi.
1. Push at [PROG] until "100" is shown on the display.
2. Push once at [] / SPAN till "101".
3. Confirm this by pushing [PROG].
4. Now the display will show 0.00 mH2O. Push at [] till 1.45 psi is on the display.
5. Confirm with [PROG].
6. The output of the transmitter will be lower than 4 mA. The output at atmospheric
pressure will be for example 3.68 mA. When a pressure of 1.45 psi is applied on the
diaphragm the output will be 4.00 mA.
The elevation can be canceled by pushing at [] till zero disappears out of the display. The transmitter is
now adjusted at 4 mA at atmospheric pressure.
SPAN ADJUSTMENT (20 mA) WITHOUT TEST PRESSURE
Before adjusting the span take care the right pressure unit is selected.
(See also P104 and P109).
Example: Adjustment of the span at 0 - 29 psi.
First off all, the pressure unit must be adjusted at psi. (See P104).
1. Push [PROG] till "100" is shown on the display.
2. Push twice at [] / SPAN until "102" appears on the display.
3. Confirm this by pushing [PROG].
4. Push [SPAN] (+) or [ZERO] (-) to select the measuring range that is required.
5. Confirm by pushing [PROG].
The transmitter is adjusted now.
P102 is the adjustment of the total span.
When a compound range must be adjusted (for example -14.5 till +43.5 psi), a span of 58 psi must be programmed.
The Zero (P101) must be set at -14.5 psi. The transmitter is adjusted at - 14.5 psi = Zero and +43.5 psi = Span.
If the process temperature at -14.5 psi is above 20 °C, another filling oil must be applied inside the transmitter (Option G26).
If the process temperature at -7.25 psi is above 60 °C, another filling oil must be applied inside the transmitter (Option G26).
CANCEL MOUNTING POSITION EFFECT
All transmitters are calibrated vertically. When a transmitter of the Series 2000 or 2000-SAN is
installed horizontally, there will be a small "mounting effect" on the zero (4 mA). For example, the
transmitter shows 4.03 mA instead of 4.00 mA. This can be easily canceled with P103. In P103
there are three options:
ESC Nothing will be changed. Leave without doing anything. (confirm with PROG).
RESET Use this option when you are not sure if P103/SET has been done in a proper
way. (confirm with PROG). When using this option, the original factory setting
will be valid.
SET Canceling mounting position effect. (confirm with PROG). When SET selected
the transmitter is automatically adjusted at 4.00 mA. Span will not be affected.
Do not apply pressure while executing "cancel mounting position effect"

ADJUSTMENT PRESSURE UNIT ON DISPLAY (See Conversion table)
Several engineering units can be shown on the display by using a conversion factor.
(See conversion table below). As standard the pressure unit of the transmitter is set to bar. Four
engineering units can be used for displaying the applied pressure on the display (mH2O,
inH2O, bar and PSI).
1. Press [PROG] until "100" appears on the display.
2. Push 4x []to get to point P104 (pressure unit setting).
3. Now press [PROG] to confirm this.
4. Now press []or []and set it to the correct pressure unit. See also the
conversion table below. The number in brackets, see Display column,
represents the menu options of transmitters with other software. Example:
3 = bar
5. Then press [PROG] again to confirm. The transmitter is now set to read in
"bar".

9. PROGRAMMING THE SERIES 2000
When using HART®or a Hand Held Terminal (HHT), a minimum resistance of 250 ohms must be
present in the loop of the 2-wire system. This is necessary for proper communication (see drawing
below). A power supply of at least 17 Vdc must be used.
9.1 PROGRAMMING WITH THE HAND HELD TERMINAL
The Series 2000 can be easily programmed with the Hand Held Terminal (HHT) from the "HART
Foundation" or the HHT from "Rosemount" (type 275 or 375 Hart Communicator).
Option 1: HART ®Handheld terminal connected across the transmitter.
Option 2: HART ®Handheld terminal connected across the loop resistor.
9.2 PROGRAMMING WITH DTM
An instruction manual is available which is a guide for installing and using the Klay Series 2000 HART DTM.
This DTM is developed to make configuration changes of Klay Series 2000 HART transmitters easy. This
DTM can be used with almost every FDT-container. The most recent version of the DTM file (zip file) is
available on: www.klay-instruments.com under section “Downloads”.
