1. INTRODUCTION
The Series DP-4000 is a high-end pressure, differential pressure and flow transmitter based upon a
piezoresistive silicon sensor, with a very high burst pressure. The sensor element is mounted in a
stainless steel body.
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 that is
proportional to the pressure/differential pressure applied. The transmitter electronics detects this
change in bridge resistance and converts it into a measuring value. The amplifier system is based on a
single microprocessor, which ensures a perfect linearity in the output, all within an accuracy of 0.075 %
or 0.065 % (option).
1.1 DESCRIPTION SERIES DP-4000
The Series DP-4000 is specially designed as a differential pressure transmitter. The wetted parts are
standard made of AISI 316L, other diaphragm materials are available, like Hastelloy C and Tantalum. The
process connections are standard fitted with ¼”NPT female thread. Oval flanges can be provide as an
option for ½” NPT (f) process connections. All process connections meet the requirements of IEC 61518.
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.
1.2 DESCRIPTION SERIES DP-4000 with separate diaphragm seals
The DP-4000 is also available with separate diaphragm seals. Standard the wetted parts are made of
AISI 316L, other materials like Hastelloy C are available as an option.
1.3 DRAIN AND VENT VALVES
As standard the DP-4000 is supplied with two drain valves. They can be screwed from the DP-4000
body to drain or vent the process. These valves must be kept clean. In case the drain valves are not
used closing/stopping bolts must be used.

EN-4000/DP-PROFIBUS-PA/10-2021/01Page 6
3. INSTALLING THE TRANSMITTER
The Diaphragm, Flange or separate diaphragm seals of the transmitter are protected with a special
protection cap. It is advisable to only remove this protection until installation takes place. Do not
damage the diaphragm, capillaries or any part of the process connection. Do not dismantle the
process connection (Sensor body).
3.1 TRANSMITTER HOUSING (Fully rotatable)
The transmitter housing can be fully rotated both ways 360° degrees.
Untighten the hexagon screw on the outside of the enclosure.
Rotate the transmitter housing to the right position and
fix the position by tightening the hexagon screw on the outside of the
enclosure. The construction prevents the housing from being rotated
too far. Where necessary the display can also be rotated separately
from the transmitter housing to the right position for most optimum
readout (§ 7.2 Rotatable display)
3.2 MANIFOLDS (Optional)
The DP-4000 can be supplied with a 3 or 5 way manifold. The manifold separates the transmitter from
the actual process. The advantage of a manifold is simple installation and easy maintenance without
interrupting the process. This means higher system availability and even simpler commissioning or
maintenance purposes. If the manifold is applied the process connection will change from ¼”NPT (f)
to ½ ”NPT (f) thread.
3.3 MOUNTING POSITION
When the transmitter is mounted horizontally, the cable gland must be pointed downwards.
3.4 MOUNTING POSITION EFFECT
All transmitters are calibrated in vertical position (diaphragm points downwards). If the transmitter is
mounted in another position, there can be a little zero shift. After installation of the transmitter the
zero must be set to 0,000 with P103 cancel mounting position effect. This will not affect the span.
After installation of the transmitter the zero must ALWAYS be set with P103 Cancel mounting
position effect. This will not affect the span.
3.5 PROCESS CONNECTION
Before mounting the transmitter, be aware of the correct position of the high and low
pressure side. The process connection is clearly marked with the symbols +and -.
3.6 CALIBRATION
All transmitters are fully calibrated at the factory, to customer specified range. If the calibration is not
specified, the transmitter will be calibrated at the maximum span.

Instruction manual Series DP-4000-PROFIBUS® PA
EN-4000/DP-PROFIBUS-PA/10-2021/01Page 7
3.7 PROFIBUS PA CABLE
Under the cover ③you will find the terminal board. Special PROFIBUS® cable must be used for proper
communication. For further detailed description of cable selection, see "Guidelines for planning and
commissioning PROFIBUS DP/PA" and "PROFIBUS PA User and Installation Guideline" both on
www.profibus.com and IEC 61158-2 on www.iec.ch.
The PROFIBUS® standard defines two variations of bus cable: Type A and Type B. However it is
recommended to use cable Type A in all new installations. Type A is recommended for high
transmission speeds and permits a doubling of the network distance in comparison to Type B.
Type A Technical specification:
Impedance: 35 up to 165 Ohm at frequencies from 3 to 20 Mhz.
Cable capacity: < 30 pF per meter.
Core diameter: > 0,34 mm², corresponds to AWG 22.
Cable type: Twisted pair cable. 1x2 or 2x2 or 1x4 lines.
Resistance: < 110 Ohm per km.
Signal damping: max. 9 dB over total length of line section.
Shielding: CU shielding braid or shielding braid and shielding foil.
Max. Bus length: 200 m at 1500 kbit/s, up to 1,2 km at 93,75 kbit/s. (Extendable by repeaters)
Using other types of cable will result in incorrect and disrupted transmissions in the PROFIBUS®
network and is strongly discouraged. Do not run wiring in open trays with power wiring, or near heavy
electrical equipment (For example frequency controllers or heavy pumps). To eliminate
electromagnetic effects it is highly recommended to us a EMC Cable gland. (Option G73)
3.8 CONNECTION TERMINAL
The figure above shows the wiring connection of the transmitter. The 2-wires must be connected to
the terminal board. The polarity of the Series DP-4000-PROFIBUS PA is independent and reversing the
polarity will not affect the functionality or damage the transmitter. The transmitter automatically
detects the polarity of the connected Profibus® cable.

Instruction manual Series DP-4000-PROFIBUS® PA
EN-4000/DP-PROFIBUS-PA/10-2021/01Page 8
The wiring terminals can be operated without a screwdriver. The opening levers of the terminals can be lifted
and pressed down by hand. Lift the opening levers of the terminals and insert the corresponding wires. Press
down the levers by hand, the terminal spring will close and the wire is clamped.
3.9 GROUNDING
The transmitter must always be connected to ground. In case the process connection is already
connected to ground (For example by the tank or pipe line), do not connect the instrument to ground.
3.10 CABLE SHIELDING
The cable shield must only be connected at one side. Optionally an EMC Cable gland can be provided
(Option G73). When a EMC Cable gland is used, the cable shield at the Profibus power supply or
installation must be disconnected.
Please ensure that the instrument is not connected to ground twice. For correct grounding
the recommendations of IEC 61158-2 must be followed.
3.11 TERMINATION
Termination of the bus prevents signal reflections on the PROFIBUS® cable. A terminator is a
combination of a resistor and a capacitor. Wrong or missing termination results in transmission errors.
At the end of each cable trunk a terminator must be used. In common a terminator is integrated in a
segment coupler. When there is no integrated terminator present in the trunk, a separate terminator
must be used.
4. REMAINING
4.1 / EMC-RULES
All Klay transmitters are manufactured in accordance with the RFI / EMC directives and comply with
the CE standard. All transmitters are fitted with RFI filters, which provide optimum, trouble-free
operation. Our products are in conformity with EMC-Directive 2004/108/EC based on test results using
harmonized standards.
4.2 TRACEBILITY / YEAR OF MANUFACTURING
The year of manufacturing of the transmitter can be traced as follows: take the first three numbers
from the serial number that is engraved in the transmitter and add 1600 to it.
Example: Serial Number 41602123. The year of manufacturing is 1600 + 416 = 2016.
