differential digital pressure gauge 

Description

Differential pressure transmitter is mainly used for HVAC, clean rooms, vacuum boiler, HVAC, wind speed measurement, leak detection, clean room, power plant air pressure, dust, air differential pressure measuring throttle control. Since the application of intelligent circuit, so that the accuracy and stability of the differential pressure measurement has been greatly improved.

Features
   Measurable damp, stale air
   A transmitter can be used for differential pressure, pressure, negative, positive and negative pressure measurements
   Range migration, range migration ratio of 10: 1
   Adjustable damping, by the dynamic pressure effect
   Zero and full point compensation correction
   Output current correction
   Display main transformer unit Optional
   Eliminate the influence of the sensor mounting position
   Output current prescribing, direction selection function
   With self-diagnosis and fault output alarm
   Non-volatile memory with EEPROM data not afraid of power loss
