Important security notes
!
WARNING
Protection against incorrect use of the measuring device:
It must be particularly ensured that the selected materials of the process-wetted parts of
the measuring device are suitable for the process media used. Failure to observe this
precaution could endanger life and limb and the environment.
!
CAUTION
At surface temperatures > 70 ° C a touch protection should be provided. The touch
protection must be designed so that the max. permissible ambient temperature of the device
is not exceeded.
CAUTION
The device may only be used within the medium pressure limits and voltage limits specified
on the rating plate depending on the explosion protection type with which the device is
operated.
NOTICE
External loads may not be applied to the transmitter.
0032/0045
The CE mark on the devices certifies the compliance with the valid EU directives for the
marketing of products within the European Community.
The following directives are applied: EMV 89/336/EWG, DGRL 97/23/EG, ATEX 94/9/EG
DGRL: Pressure transmitters are pressurized equipment parts in the sense of the
pressurized devices directive.
The CE mark is awarded according to classification in the appropriate categories.
Devices without the CE mark comply with the pressurized devices directive and are
manufacturer in accordance with "good engineering practice".

WARNING
Notes for the operation of the intrinsically safe version in hazardous areas:
Operation is only permissible on certified intrinsically safe circuits- The transmitter
corresponds to category II 2G.
The EC type test certificate applies for installation of the device in the walls of vessels and
pipes in which explosive gas/air or vapour/air mixtures occur only under atmospheric
conditions (pressure: 0.8 bar to 1.1 bar; temperature: -20 °C to +60 °C). The permissible
range of the ambient temperature is -40 °C to +85 °C, in hazardous areas -40 °C up to a
maximum +85 °C (at T4).
The owner may use the device under non-atmospheric conditions outside the limits
specified in the EC type test certificate (or the test certificate valid in his country) on his
own responsibility if additional safety precautions have been taken according to the
conditions of application (explosive mixture). The limits specified in the technical data
(page 32) must be observed in any case.

Application
The SITRANS P Compact transmitter converts pressures into a load-independent current of e.g. 4 to
20 mA at high accuracy. It has been developed for the special requirements of the
food/pharmaceutical/biotechnology industries.
Particular value has been placed on a high surface quality. It is therefore possible, for example, to
guarantee roughness values down to Ra = 0.4 µm (1.57
· 10-8 inch) in the wetted area it required (welded
seam range: Ra < 0.8 µm (3.15
· 10-8 inch)). The system can be electro polished in addition. A further
important feature is the hygiene-based design of the process connection by means of various aseptic
connections.
The completely welded stainless steel housing (optionally also with plug or cable outlet) can be designed
up to degree of protection IP67, and is therefore easy and safe to clean.
Using appropriate thermal decouplers, the transmitter can be used for process temperatures up to 200 °C
(392 °F).
Major features
• Measuring ranges from 0 to 160 mbar (0 to 2.32 psi) up to 0 to 40 bar (0 to 580 psi)
• Linearity error including hysteresis < +0.2% of full-scale value
• Piezo-resistive measurement system, vacuum-proof and overload-proof
• Hygiene-based design according to EHEDG, FDA and GMP recommendations
• Material and surface quality according to hygiene requirements
• Wetted parts made of stainless steel; completely welded
• Signal output 4 to 20 mA
• Stainless steel housing with degree of protection IP65; IP67 as option
• Process temperature up to 200 °C (392 °F)
• Ex protection II2G EEx ib IIC T6 to ATEX
Mode of operation
The process pressure acts on a piezo-resistive semiconductor measuring bridge via a remote seal and a
transmission liquid. The transmitter converts the pressure values into a load-independent current.
A compensation network makes the output signal largely independent of the ambient temperature. As a
result of a specially adapted remote seal connection with minimized volume, the influence of the process
temperature on the output signal is greatly reduced compared to a conventional screw connection.
The electronics is potted to protect it against moisture, corrosive atmospheres and vibration.
The pressure transmitters can be powered with a non-regulated DC voltage of 10 to 30 V. Output signals
common to measuring technology are available.
