1 Introduction

Series PUM01-03 pressure transmitter are noted for their reliable function and easy operation. To obtain the
greatest benefit from this device, please observe the following cautionary statement:

Persons who are responsible for setting up or operating this device must be sure to read the and
understand the operating instructions and the safety information pertaining to it.

2 Safety Information

2.1 General Instructions

To ensure safe operation, the device must only be operated according to the information in the operating
instructions. When the device is in use, the regulations and safety standards applicable to the specific
application must also be observed. This statement also applies to the use of accessories.

2.2 Proper Usage

Series PUM01-03 pressure transmitters are designed to transform a pressure into an electrical output signal.
Any application extending beyond this specific intended use does not constitute proper usage.
Series PUM01-03 pressure transmitters must not be employed as the sole means of avoiding hazardous
conditions in machinery and installations.
The machinery and installations must be designed in such a manner that faulty conditions and malfunctions
will not present hazardous situations for operating personnel.

2.3 Qualified Personnel

Series PUM01-03 must only be used by qualified, knowledgeable personnel trained in correct use of these
devices. Qualified personnel are those persons familiar with setting up and assembling these devices, placing
them in service and operating them. In addition, such personnel must also be qualified to perform the work
associated with the application for which the device is being used.

3 Functional Description

The pressure is sensed in the transmitter by means of a piezo-resistive cell or a thin-film cell. The resulting
resistance signal, varying with the pressure, is converted by an amplifier to a current or voltage signal.

4 Installation Instructions

4.1 General Information

The actual operating pressure and temperature of the installation must not exceed the maximum values
specified. The pressure ports must only be opened with the system depressurized. Please note that in a given
system, the component with the lowest maximum pressure rating will determine the maximum permissible
operating pressure for the entire system.

4.2 Pressure Transmitter (high-pressure version)

For the proper tightening torques, please refer to the documentation from the supplier of your high-pressure
piping.

5 Electrical Connection

For the pin assignment, please refer to the label on the transmitter.

6 Care and Maintenance

PKP pressure transmitters are maintenance-free.
Recommended recalibration interval: 1 year

Pressure Measurement and Monitoring Systems

PUM03

High-Precision
Pressure Transmitter
in Stainless Steel

• Accuracy class 0.25

• Measures relative or absolute pressure

• Optional flush-mounted
stainless steel diaphragm

• Sturdy, heavy-duty design

• Current or voltage output

Description:

Model series PUM03 pressure sensors have a piezo-resistive
sensor element for pressure ranges up to 16 bar. This ele­ment very accurately registers changes in pressure through
the change in the electrical resistance of the piezo crystal
caused by variation in the mechanical force exerted upon it.
For higher measuring ranges, thin-film technology
is used due to its fast reaction times. This method translates
the changes in resistance in an extremely thin strip of ex­panding film into an output signal that is proportional to the
mechanical force exerted upon the film. The combination of
these two technologies allows this device to meet all DIN
measuring ranges from -1/0 bar to 0/2500 bar with consistent
accuracy.

Fields of Application:

The sturdy design of PUM03 pressure transmitters allows
accurate measurement of gases and liquids in a process,
even under rough service conditions. A stainless-steel dia­phragm protects the transmitter measuring system from
damage, allowing a great variety of media to be measured
as long as they are not highly viscous or crystallizing. If
necessary, the pressure transmitter can be fitted with a flush­mounted diaphragm which prevents these kinds of materials
from entering the housing and hardening there. The electri­cal signal at the output can be remotely transmitted or used
for direct display. For direct display of readings, we recom­mend the PKP AZ01 digital display, which can be easily
installed between the transmitter and the plug connector.
This display does not require a separate power supply.
