Industrial High Accuracy Modbus Smart Pressure Transmitter Circuit Board
China Industrial High Accuracy Modbus Smart Pressure Transmitter Circuit Board, Find details about China Modbus Transmitter Circuit Board, RS485 Circuit Board from Industrial High Accuracy Modbus Smart Pressure Transmitter Circuit Board
With the main body of Microcontrollers CPU, JT2088-RS485 Diezoresistive Intelligent Circuit Board is capable to do logical operation and programming, combining analog and digital circuit in one machine. Isolatio
n technology is used in power and signal information collection and digital communication to ensure good performance in harsh industrial working environment. 20 bits AD switch ensures high accuracy pressure collection and switch; as for communication RS485 circuit is adopted, so as to realize Modbus-RTU protocol or user-defined protocol. Buttons set normal parameters of transmitters; free adjusting programs provide parameters configuration, pressure calibration, temperature compensation and other operations. Maximum 7 points calibration improves precise level and accuracy of transmitters. JT2088-RS485 supports standard diffused silicon, strain gauge,piezoresistive ceramic etc pressure and level sensors. It is suited for 2088 housing.
