In addition to the differential pressure, the P92 differential-pressure transducer also records positive and negative overpressure. The process variables are transformed into normalised signals. Pressure is measured via a diaphragm spring made of CuBe, whose displacement is recorded inductively. A microprocessor guarantees high precision and great flexibility. This differential-pressure transducer is particularly suitable for high-quality applications, such as pressure monitoring in clean rooms, laboratories, pharmaceutical plants and operating theatres, as well as for special applications in mechanical engineering. The 3 or 4-figure LC display is available as an option. In addition to Pa and kPa, it can also display other units of pressure. An optional time constant up to 5 s means the device can also be used under fluctuating pressure conditions and generates a stabilised output signal. Halstrup
