Interfaces for safety pressure sensors.

The STW (Sensor-Technik Wiedemann) pressure sensors of the F02 Safety series from the modular sensor system for mobile hydraulics, now can provide the “Deutsch DT04” connector as an additional electrical connection option in addition to a 5-pole M12 connector.

The “Deutsch DT04” connector is mainly used in the automotive sector. With the E1 approval already available, the pressure sensor designed for safety applications can now be integrated even more easily into vehicles. In addition, the sensor now also supports a ratiometric output signal, which changes proportionally to the supply voltage. This signal is less susceptible to interference and can be easily processed in a subsequent analog-to-digital conversion in vehicle wiring systems that can fluctuate greatly, as the supply voltage of the vehicle can be used as a reference.

The F02 Safety is designed for applications, which require a Performance Level PL d or a Safety Integrity Level of SIL 2.

It is based on the proven type M01 and has a thin-film measurement cell made from stainless steel, which is welded together with the pressure sensor, thus guaranteeing high media compatibility. The multitude of available pressure connections, the large supported pressure range, the excellent EMC compatibility as well as the small constructional design offer the greatest possible flexibility in the application or during design-in.

The F02 Safety is part of the STW modular sensor system for mobile hydraulics. It offers various products for the acquisition of physical parameters such as temperature, pressure, strain, inclination and angular velocity, as well as pressure switches in a functionally safe design. In mobile machines, the measured values are used, among other things, for monitoring and controlling the drive, work function or energy management and can also be made available on the Internet e.g. for predictive maintenance measures using onboard software and cloud solutions from STW. Furthermore, STW sensors are known for their particular resilience and durability.
