METPOINT® PRM
Sensor technology for precise pressure monitoring
The METPOINT PRM pressure transmitter measures relative pressure (gauge pressure) in gaseous and liquid media and converts this reading into a linear output signal. Pressure transmitters convert physical pressure into an electrical signal proportional to the pressure.
Measuring range
0 to 60 bar (g)
Accuracy
< 0.5 %
Output
4 to 20 mA
Protection rating
IP67
Precise pressure monitoring and system integration with METPOINT PRM
Would you like to measure differential or system pressures reliably? The pressure sensors of the SP11, SP21 and SP22 series provide precise monitoring of system pressures. The recorded readings form a solid basis for the maintenance and optimisation of production plants. In addition, the accurate pressure data enables fact-based business decisions. Thanks to a wide range of interfaces, the sensors integrate seamlessly into existing process control systems.
High-precision sensor technology in the METPOINT PRM
The METPOINT PRM uses sensors with thin-film technology. The base body and diaphragm of a metal thin-film sensor are made of stainless steel 1.4548. On the side of the diaphragm facing away from the medium, insulating layers, strain gauges, compensation resistors and conductor tracks are applied using a combination of chemical and physical processes and then structured photolithographically by etching. The layers of the resistors and electrical conductor tracks on the sensor are considerably thinner than one micrometre and are therefore referred to as thin-film resistors.

Frequently asked questions
What does the METPOINT PRM measure?
It measures relative pressure (gauge pressure) in gaseous and liquid media and converts it into a linear electrical output signal.
What do I use the pressure readings for?
For reliable monitoring of system and differential pressures. The values provide a basis for maintenance, optimisation and business decisions.
Which measuring ranges are available?
Depending on the type, 0 to 16 bar, 0 to 25 bar or 0 to 60 bar gauge.
How accurate is the METPOINT PRM?
The accuracy is better than 0.5 %.
What sensor technology does the METPOINT PRM use?
A metal thin-film sensor. The base body and diaphragm are made of stainless steel 1.4548; strain gauges and conductor tracks are applied to the back using the thin-film process.
Can the sensor be integrated into an existing control system?
Yes. The sensor supplies an analogue signal of 4 … 20 mA and can be integrated into existing process control systems via its interfaces.
Under what ambient conditions does the sensor operate?
At ambient temperatures from −25 to +85 °C. The housing meets protection class IP67.
