Industrial High Accuracy Modbus Smart Pressure Transmitter Circuit Board

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 switch6. 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 source10. Small signal wiping off function, wipe-off rate settable Technical Parameters- Intelligent Pressure Circuit Board   Supply powerDC18-36V (DC 24V is suggested)Operation mode Four-wire (two wires offering power + two wires communication)Sampling rate20times/sDisplaying and bitsLCD with backlight, displaying 6 bits, and 5 decimal placesDisplaying units Ten displaying units as KPa, Pa, MPa, mmH2O, mH2O, mbar, bar, PSI, M,%Temp. compensation accuracy-30~70ºC complete machine accuracy is better than 0.5% (including accuracy of sensor)Linearity accuracyComplete machine linearity is better than 0.2% (Multi-point calibrating is available as required)Stability0.2%/YearRange ratio10:01Circuit protection Measurement surge current protection, reverse power protectionCircuit design Intrinsic safetyIsolation range>200MRS485 communication ProtocolModbus-RTURS485 communication rate9600bpsAdjusting methodby buttons on LCD head or program on pcDimensions OD=52mm, Mounting hole pitch=44mm (suited for pressure and level transmitter in 2088 housing)Motherboard buttons operationreset, lower range calibration(zero drift under pressure source), upper range calibration (full scale calibration)LCD head buttons operationchanging machine address (0-255), units, decimal place, damping time and zero clearingWhy choose WNK?1.
