RS485/HART intelligent pressure transmitter

RS485/HART intelligent pressure transmitterIt is an intelligent pressure measuring instrument with precision and stability. The measuring element adopts sensors, combined with single-chip computer technology and digital conversion technology for precision digital temperature compensation and nonlinear correction. The integrated structural design and standardized 4-20mA or fieldbus RS485 signal output can meet the increasing demand for precision pressure measurement and control in industrial fields.

The product can adopt a two-wire working mode, with zero point automatic adjustment and temperature automatic compensation functions, strong anti-interference ability, and is an upgraded product that simulates a two-wire 4-20mAADC transmitter. The RS485 type can achieve passive calibration of transmitter zero and full range, range scaling and parameter setting, and flexible networking of digital interfaces (up to 99 units) through the upper computer software provided by the factory. The HART protocol type allows for on-site configuration of the transmitter through a handheld device or configuration system, making operation and maintenance simple and convenient.
