High Anti-Interference Hart Capacitive Pressure Transmitter Circuit Board

JT3051CH Capacitive HART Circuit Board JT3051CH Capacitive HART Circuit Board uses advanced completely isolation technology. The power side is islolated by transformer, signal side isolated by opticalcoupler to make transmitters with good anti-interface, thus ensure high realiability and stability. Parameters configuration and compensation of transmitters can be done by buttons, HART communicators or HART configuration programs, improving precise level and accuracy of transmitters. JT3051CH matches capacitive differential pressure sensor and is suited for 3051 housing.Features - JT3051CH Capacitive HART Circuit Board: 1.Easy adjusting by buttons: on-site span changing by LCD module buttons free from standard pressure source; for headless type, PV reset and span correction with pressure source done by buttons on mainboard 2.High accuracy: for intelligent board, AD accuracy > 20 bits, DA accuracy > 16 bits;3.Good stability: Linearity better than 0.1%, temperature conpensation accuracy better than 0.5%4.Data backup and restore5.Eletrical isolation: >1500VDC6.Communication protocol:4~20mA output with HART protocol digital communication (two wires) 7. Adjusting method: through communicator or telemanagement via PC configuration adjusting programTechnical Parameters - JT3051CH Capacitive HART Circuit Board: Supply powerDC12-32V (DC 24V is suggested)Matching sensorMetal capacitive sensorSampling rate>20times/sDisplaying and bitsLCD with backlight, displaying 5 bits, and 4 decimal placesDisplaying interfaceEnglish or Chinese,displaying pressure, temperature/current/ percentage(interactive display) and 0-100% analog displayingDisplaying unitsDozens of displaying units, kPa, m4H2O, MPa, M, inH2O etc.Output resolution1uATemp. 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%/YearAnti-disturbance Power isolation, signal isolation (magnetic isolation)Range ratio100:01Circuit protection Measurement surge current protection, Reverse Power ProtectionCircuit design Intrinsic safetyIsolation range>200MCommunication ProtocolHARTAdjusting methodby buttons on LCD head or program on pc, HART communicatorDimensions OD=61mm, Mounting hole pitch=55.14mm (suited for gauge,differential, micro differential pressure transmitter in 3051 housing)Motherboard buttons operationreset, lower range calibration(zero drift under pressure source), upper range calibration (full scale calibration)LCD head buttons operationchanging span units, decimal place, damping time, currant fixing, output features, current fixxing, write-protection,calibration (zero clearing, lower point and full scale calibration), language setting, media density (only unit M) and factory resetWhy choose WNK?1.
