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
