The pressure transmitters of the 22M series with brass housing were designed to be a reliable solution for automotive and industrial applications. They are homologated and can be used, for instance, to measure the content of the gas tank in bivalent vehicles.

The programmable pressure switches of the 22-PS series are encased in a compact yet robust steel housing and are available with PNP or NPN wiring. The pressure switches can be supplied pre-configured at the customer's request. With the aid of the dV22-PP programming unit (available for purchase separately), the two switch outputs can be programmed at any time to be normally closed or normally open at a range of switching points with a window or hysteresis function.

The pressure transmitters of the 22S series were designed for use in automotive and industrial applications. They are homologated and every one of their elements has been configured for optimum reliability. In this steel version of the 22 series, all parts that come into contact with media are made of stainless steel (AISI 316L).

The highly dynamic and compact 21PHB pressure transmitter is suitable for use in liquids and gases, and can process pressure changes with a bandwidth of 20 kHz. This is achieved by means of the continuous analog signal that is adjusted by a digital circuit in real time and is amplified to a standardised 0...10V signal. The miniature sensor head with a fine M6 thread can withstand temperatures of up to 100 °C and is overload-proof up to a magnitude of four times the measuring range.

The 22DT series has been specially developed for use in bivalent vehicles (volume flow measurement when running on natural gas) and is homologated for the automotive industry. However, it also has other industrial applications. The NTC or PT temperature sensor located directly beneath the steel diaphragm reacts more quickly to temperature changes thanks to its special design. The pressure transmitters are protected against electromagnetic fields up to 200 V/m and output the measured values as a ratiometric 0,5...4,5V analog signal. The connections of the temperature sensor are fed out directly.
