Difference pressure sensor DIFF20 with standard output 4..20mA

difference pressure sensor

  • sensor for the registration of difference pressures
  • laser-trimmeded measuring sensor
  • hardware-based compensation of the temperature dependence
  • durable casing
     Order number
  • DIFF20 10155 (standard output 4..20mA)


Electronic measuring sensor for the registration of difference pressures.

The primary pressure absorber is based on a silicon absolute pressure sensor item, whose function is based on the piezo-resistive effect. It has an internal active temperature compensation for a wide temperature range. This is achieved by an integrated signal processor that realizes an extensive correction of the course of temperature.

The electrical measuring signal is changed into a standardized output signal in a following switched transducer electronics.

The sensor is supplied in a sturdy and impact-resistant plastic casing.
