Proper use
METPOINT®SP11 7
5 Proper use
The METPOINT®PRM pressure transducer detects the relative pressure (gauge pressure) in gaseous and
liquid media and transforms this measured value into a linear output signal 4 … 20 mA or 0 … 10 V.
Pressure transducers transform the physical pressure into a pressure-proportional electrical signal. De-
pending on the version, there are different measuring principles which form the basis of the pressure moni-
toring.
The METPOINT®PRM pressure transducer is exclusively designed and constructed for the proper applica-
tion purpose that is described herein and must be used correspondingly.
A check in order to ascertain whether or not the device is suitable for the chosen employment must be car-
ried out by the user. It must be ensured that the medium is compatible with the components which come into
contact with it. The technical data listed in the data sheet are binding.
Improper handling or operation outside the technical specifications is impermissible. Claims of any kind on
the basis of improper use are excluded.
6 Exclusion from the field of application
•The device is not suitable for use in hazardous areas.
•The device is not suitable for application with corrosive gases.
•Corrosive fluids must not be conducted through the pressure transducer.
•Improper handling or operation outside the technical specifications.

Function
14 METPOINT®SP11
10 Function
The METPOINT
®
pressure transducer of the PRM-SP series de-
tects the relative pressure (gauge pressure) in gaseous and liq-
uid media and transforms this measured value into a linear, pres-
sure-proportional electrical output signal of 4 … 20 mA or 0 … 10
V.
As regards the METPOINT®PRM, sensors of the thin-film tech-
nology are employed.
The body and membrane consist of 1.4548 stainless-steel materi-
al. On the membrane side that faces away from the medium, insu-
lation layers, strain gauges, compensating resistors, and conduc-
tors are applied with a combination of chemical and physical
methods, and are photolithographically structured through etch-
ing. The layers of the resistors and electrical
conductors applied on the sensor are considerably thinner than a
micrometer and are, therefore, called thin-film resistors.
Due to the materials used, the metal thin-film sensor boasts
very good resistance to many media and it is insensitive to
shocks and vibration impacts.
Since the employed materials are easily weldable, the sensor is
hermetically welded onto the pressure connection, without need-
ing additional sealing material.

11.1 Installation instructions
Warning!
Risk of injury in the event of insufficient qualifications!
Improper use can lead to significant personal injury and material damage.
All of the activities described in these operating instructions must only be carried out by qualified
personnel with the qualifications described hereinafter.
Qualified personnel
Due to the specific training and knowledge concerning the measuring and control technology, and due to
their experience and knowledge of the country-specific provisions, standards in force and directives, qualified
personnel are capable of carrying out the described work and of independently identifying the possible risks.
Special employment conditions require further corresponding knowledge, e.g. regarding aggressive media.
Danger!
Compressed air!
Risk of serious injury or death through contact with quickly or suddenly escaping compressed air
or through bursting and/or unsecured plant components.
Measures:
•Only carry out installation works when the system is pressureless.
•Only use pressure-resistant installation material.
•Do not exceed the max. operating pressure (see type plate).
•Check the installation point for tightness subsequent to installation.
Warning!
Risk of injury through temperature!
Risk of injury through the contact with very high or low temperatures.
Measures:
•Prior to installation or removal of the pressure transducer, carry out a temperature compensation or
wear protective gloves.
Note:
It is imperative to observe all of the listed hazard and warning notes.
Please also observe all the provisions and instructions regarding the occupational safety and fire
at the respective point of installation.
As a matter of principle, only use suitable tools and material in a proper
condition.
Bear in mind that condensates can contain aggressive and harmful components.
Therefore, avoid contact with the skin.
Caution!
Malfunction at the pressure transducer!
Through incorrect installation, malfunctions may occur at the METPOINT®PRM pressure trans-
ducer. These can lead to incorrect measuring results and to misinterpretations.

Installation

11.2 Preparing the thread at the measurement point
In order to install the pressure transducer, a receiving thread is required at the measuring point. The latter
must already show the following specifications or must be prepared correspondingly:
11.3 Installation example for connections in accordance with EN 837-1 with a cylindrical thread
In order to seal the process connection (1) with a cylindrical thread (3) at the sealing surface (4), flat gaskets
(2) are employed.
Installation steps
•Use a suitable gasket for the sealing (2), e.g. a copper gasket, corresponding to the measuring medium
and the pressure to be measured.
•The sealing surface (4) of the part to be received must have a perfect, clean, and undamaged surface.
•Manually screw the pressure transducer into the receiving thread.
•Do not twist the thread turns during the screwing-in.
•Only screw-in or unscrew the device via the spanner flats using a suitable tool, and with the specified
torque. The correct torque depends on the dimension of the process connection and on the used gasket
(shape/material). During the screwing-in or unscrewing, do not use the housing as a working surface.
•Subsequently, tighten the threaded-end fitting with the open-end spanner (for G¼" max. 20 Nm).

12 Electrical installation
The nominal value for the supply voltage for the electrical installation is 24 V DC.
Supply of the METPOINT®PRM SP11 must be implemented with a stabilised, short-circuit-protected power
supply that is protected against overvoltage. The energy supply must come from a source with an energy-
limited electrical circuit (10 A max./ 30 V max.) and a protective separation from the network. See also EN
61010-1, Clause 9.4.
Prior to the installation and start-up, the maximum load resistance must be observed. With a nominal value
of the supply voltage of 24 V DC, the max. load resistance is 571 Ω. With a supply voltage that deviates from
24 V DC, the max. load resistance can be calculated according to the following formula:
RL ≤(Uv- 12 V) / 0.021 A [Ω]
Warning!
Risk of injury in the event of insufficient qualifications!
Improper use can lead to significant personal injury and material damage.
All of the activities described in these operating instructions must only be carried out by
