FAQ about sensor technology and transducers with continuous output signals

What does “continuous output signal” mean and when is it used?

A continuous output signal, e.g. 4–20 mA or 0–10 V, provides a continuous, analog measured value. These signals are ideal for precise process monitoring, e.g., for pressure, temperature, or humidity—both in industry and in hazardous areas.

Are pi safety sensors, transducers, and switching amplifiers suitable for use in hazardous areas?

Yes – our models such as TR.Ex, SW.Ex and the associated sensors are certified according to ATEX / IECEx and can be used in zones 1, 2, 21 and 22. Measurement acquisition up to zone 0. They meet all requirements for safe operation in gas and dust atmospheres.

In which temperature ranges can the devices be used?

All sensors and transmitters are designed for temperatures from –40°C to +70°C – ideal for industrial environments and demanding outdoor areas.

What output signals are available?

As standard, our pi safety sensors and transducers deliver an analog signal of 4–20 mA or 0–10 V – suitable for all common control systems.

How is the electrical connection made?

The pi safety sensors and transducers with continuous output signal are equipped with M12 connectors and terminal connections. This enables quick, error-free integration into existing systems (plug-and-play).

What is the difference between a sensor and a transmitter?

A sensor measures a physical quantity (e.g., pressure), while a transmitter converts this signal into a standardized analog signal (e.g., 4–20 mA).

What protection class do the devices have?

All pi safety products have protection class IP66 – they are dustproof and protected against strong water jets.

Can the sensors be individually parameterized?

Yes – many models allow easy on-site parameterization without additional software. This allows measuring ranges or signal types to be flexibly adjusted.
