differential pressure type digital pressure transducer

Description

      ACD-302digital pressure transmitter adopts imported sensor with superior productperformance, higher measuring precision, longer service life, better long-termstability and less maintenance. It could expand various communicationinterfaces while the standard analogue signals are output, which is the idealpressure transmitter.

Applications

* Substitute of imported pressure transmitter
* Can be used for the pressure monitoring and teleportation of oil well and gaswell
* Applicable for the extensive pressure parameters networking acquisition

Features

* Measurement range could be modified; therecommended range shall not be more than 3:1
* Optional RS485 communication function and 4～20mA current output
* Output current resolution can be up to 3uA
* Always online communication technology, bus support 255 devices with RS485
* Unique anti-radio frequency technology, matching with data radio remotemonitoring perfectly
* Enhanced thunderbolt prevention technology, to ensure the instrument to worksafety
* Zeropoint homeostasis technology
* Temperature compensation technology
