High response differential pressure with 10kHz frequency rensponse

High response differential pressure transducer with 10kHz frequency rensponse. PT-161A for gases and PT-162A for gases & liquids. PT-162A comes with air-purge function.

Edge & Function


*Test with high response (Frequency response 10kHz)

*PT-162A can be used for both gases and liquids

*PT-162A is spalash proof type transducer and comes with air-purge function

*With one PT-161A & PT-162A, the usage of Differential pressure and Gauge pressure can be selected

*Built-in amplifier minimize the noise effect


PT-162A can be used as a difital pressure gauge if combining with DP gauge
