Precise pressure measurement for industrial applications

Measure, control, optimize: Our pressure sensor continuously records system pressure and converts it into a proportional electrical signal. Your controller receives it as an analog 4–20 mA or 0–10 V signal, depending on the version, with accuracy up to 0.25%. This allows you to see not only whether a limit value has been reached, but how the pressure develops during operation. The measuring ranges extend from 0.1 bar to 600 bar, so a suitable version is available for low-pressure applications as well as for high system pressures. Wetted parts made of stainless steel and a compact, robust design ensure that the sensor operates reliably even where vibration, temperature fluctuations, and environmental influences are part of everyday operation.

FAQ

Pressure Sensors

What is the difference between a pressure sensor and a pressure switch?

A pressure sensor provides a continuous signal proportional to pressure, while a pressure switch only monitors a fixed switching point.

Which output signals are available?

Typical signals are 4–20 mA or 0–10 V.

Which media are the sensors suitable for?

For liquid and gaseous media, provided they are compatible with stainless steel.

How accurate are the sensors?

Depending on the version, measurement accuracy up to 0.25%.

Are the sensors suitable for industrial environments?

Yes, they are designed for vibration, temperature fluctuations, and harsh operating conditions.

Can different pressure ranges be covered?

Yes, from 1 bar up to 600 bar. Further ranges on request.

Are different connection variants available?

Yes, both electrical and process-side connections are variable.

Are the sensors suitable for OEM applications?

Yes, in particular due to the wide range of variants and good availability.
