1INLEIDING
The Series TT-2000 is a complete Stainless Steel temperature transmitter, based on a Pt-100 element
(1/3 DIN class B). The range of standard elements can be set between -50 and 200 °C. Other ranges
are available on request. The Pt-100 element is mounted in a stainless steel plug (sensor position 9).
To obtain an accurate and fast measurement, the diameter of the insert part has to be chosen as small
as possible. The resistance change of the Pt-100 element due to temperature change is converted into
a proportional 4-20 mA signal (2-wire).
A great diversity in designs and process connections can be made including milk couplings (DN25, 40
and 50), Tri-clamp (1, 1 ½ "or 2") and hygienic weld-on-nipples like ¾ "BSP nut (diameter 28 mm).
Associated immersion tubes (Thermowell) fully welded and manufactured from execution (bar stock)
are available in various designs and materials (on request).

3 INSTALLING WELD-ON NIPPLE
A skilled machinist or welder should perform installation of the weld-on nipple.
Weld Argon, MIG or TIG with the smallest welding pin.
1. Cut a hole in the process vessel/pipe to accept the weld-on nipple.
2. Remove the weld-on nipple from the transmitter.
3. Position a welding mandrel into the weld-on nipple and screw it down.
WARNING
Never weld the entire nipple at once.
Excessive heat input will deform the weld-on-nipple.
Cool each and every well after each welding cycle.

H/EN/2000-TT/09-2021/09 Page 4
4. Position the weld-on nipple in the vessel hole and tack six places.
5. The weld sequence is shown in the figure above. Weld the weld-on nipple in place using
0,03 to 0,045 in. (0,762 to 1,143 mm) stainless rod as filler material in the beveled area.
Adjust amperage for penetration pliers (1/8").
6. Remove mandrel after the welding operation.
3.2 MOUNTING POSITION
When the transmitter is mounted horizontally, the cable gland must be pointed downwards.
3.3 CALIBRATION
All transmitters are fully calibrated at the factory, to the conditions stipulated in users order. When the
customer has not requested calibration, the transmitter will be calibrated 0-100 °C.
3.4 WIRING
Under the cover (3) you will find the terminal board. Under the other cover (1) are the buttons for the
zero and span adjustment.
External loads must be placed in the negative leg 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 signal wiring must be shielded and twisted pairs
yield best results. 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 mounting position is already connected to
earth (by tank or pipe line) do NOT connect the
instrument to earth. Please ensure that the instrument
is not connected to earth twice to prevent the
occurrence of an 'earth loop'. In applications with
synthetic mounting positions the case grounding
terminal (internal or external) must be connected to
earth.
Care must be taken to assure that the polarity of the power supply is correct, a reversal of wiring
polarity will not damage the transmitter, but it will not function until the wiring is connected correctly.
4. REMAINING
4.1 DIGITAL LOCAL INDICATOR
All temperature transmitters from the series TT-2000 are standard equipped with a digital display. In the
standard version closed covers are used. The push buttons and the display are behind the cover (3).
As an option an transparent cover can be delivered for the application as a local display in the process
(Option: "I" extra price). The full-scale point may be set to any value between 0000 and 9999 (4 digit)

4.2 CE / EMC Rules
All transmitters are fitted with RFI filters, which provide optimum, trouble-free operation. Our products
are in conformity with EMC-Directive 2014/30/EU based on test results using harmonized standards.
4.3 EXTERNE RESISTOR
The minimum power supply is based on the total circuit
resistance. The maximum permissible load(Rimax.) in case of 24
Vdc is 600 Ω (Ohm).
By increasing the power supply, the external load can be
increased to 1200 Ohm / 36 Vdc. (see figure left).
Rimax. = Supply - 12 V (minimal supply)
20 mA
With a loop resistance of 250 Ω a power supply of at least 17 Vdc must be used.

4.4 TRACEBILITY YEAR OF MANUFACTURING
The year of manufacturing of the transmitter can be traced as follows: take the first two numbers from
the serial number that is engraved in the transmitter and add 1970 to it.
For example: if the 3902123. The year of manufacturing is 1970 + 39 = 2009.
4.5 SOFTWARE REVISIES
Due to the improvements on the Series TT-2000, there are several software versions (revisions). For
this reason it is possible the temperature transmitter you are working with does not support some
options, which are discussed in this manual. Ask Klay Instruments BV.
5EXPLANATION PUSHBUTTONS
The Series TT-2000 can be programmed easily by use of
the 3 front panel pushbuttons (See picture right).
On het display several engineering units can be
used: °C, °F, mA and %
The functions of the three pushbuttons will be explained
below.
This button has 2 functions:
It can be directly used for adjusting the
zero (zero / 4mA), with or without a test pressure. When the zero (4 mA) must be
adjusted at 0 °C, the button must be held until the word "ZERO" appears on the display.
The transmitter is now set to 4 mA.
Test temperature should be 0 °C.
Also, this button must be used for stepping down in the programming menu
or to decrease a value (-).
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 (50 °C) is supplied to the transmitter, the button must be held until the
word "SPAN" appears on the display. The transmitter is adjusted at 0 - 50 °C.
Also, this button must be used for stepping up in the programming or to
increase a value (+).
This button has 2 functions:
It is used to adjust the 11 Programming Points (P101 to P111). Push it once and P100 is
displayed, use the [] (SPAN) to step to P101 etc.
This button must also be used for confirming the adjustments (enter).

SPAN ADJUSTMENT (20 mA) WITHOUT TEST TEMPERATURE
Before adjusting the span take care the right temperature unit is selected.
(See also P104 and P108).
Example: Range 0 - 100 °C
1. Push [PROG] till "100" is shown on the display.
2. Push twice at [] / SPAN until "102" is 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 TT-2000 is adjusted now.
P102 is the adjustment of the total span. When a compound range must be
adjusted (for example -30 till +70 °C), a span of 100 °C must be programmed. At
P101 (ZERO,4 mA), -30 °C must be adjusted. Now the transmitter is adjusted at:
- 30 °C = 4 mA and +70 °C = 20 mA.
ADJUSTMENT TEMPERATURE UNIT ON DISPLAY
Several engineering units can be shown on the display by using a conversion factor.
(See conversion table below). As standard the read out from TT-2000 is set to ‘Degr ‘
(degrees C). To change this setting, the following must be set:
1. Push at [PROG] till "100" is shown on the display.
2. Push 4 times at [], go to [P104].
3. Push at [PROG] to confirm this.
4. Push at [] / [SPAN] (+) and set it to Fahr (See conversion table below).
5. Push [PROG] to confirm.
The transmitter will now read out in ‘Fahr’
For correct conversion between both temperature scales the following conversion
calculation must be used.
Celsius naar Fahrenheit
°C = (°F −32) × 5⁄9
Fahrenheit naar Celsius
°F = °C × 9⁄5+ 32
When the value of the highest range is larger than 9999, "NA" will appear in the display
(Not Applicable). Another unit must be chosen.
REVERSE OUTPUT (20 - 4 mA or 4-20 mA)
The transmitter as standard is adjusted to 4-20 mA.
