Product Description
JT2088 Diezoresistive Intelligent Pressure Circuit BoardWith 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. Isolation 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.
Features - Intelligent Pressure Circuit Board 1. Four wires working mode (two wires offering power + two wires communication)
2. Various gain optional, suitable for micro signal output sensors;
3. Temperature compensation, under -30~70ºC the accuracy is better than 0.5%;
4. Three points calibrating, linearity accuracy better than 0.2%. Multi-point calibrating is available as required.
5. High accuray: 20 bits AD switch
6. Isolation RS485 communication technology ensures realiable communication;
7. MODBUS protocol (customized private protocol is available) realizes data communication, thus applicaiton is wide;
8. Various pressure units ( unit "M" combined with media density realizes height measurement)
9. span can be changed on-site by LCD module buttons without standard pressure source
10. Small signal wiping off function, wipe-off rate settable
