Diezoresistive Hart Circuit Board with LCD Display

JT3051TH Diezoresistive HART Circuit BoardJT3051TH Diezoresistive HART Circuit Board replaced the original 4~20mA analog board. With the main body of Microcontrollers CPU, JT3051TH is capable to do logical operation and programming, combining analog and digital circuit in one machine, so it is able to output analog signal as well as carrry HART protocol signal on 4~20mA analog signal. Parameters configuration and compensation of transmitters can be done by buttons, HART communicator and HART configuration programs. JT3051TH provides constant current excitation way for sensors, supporting standard diffused silicon, piezoresistive ceramic, single crystal silicon and level sensors. It is suited for standard 3051 housing.Features - Diezoresistive HART Circuit Board: 1.Easy adjusting by buttons: on-site span changing by LCD module buttons free from standard pressure source2.High accuracy: for intelligent board, AD accuracy > 20 bits, DA accuracy > 16 bits;3.Electrical isolation: > 1500VDC4.Good stability: Linearity better than 0.05% (with sensors), temperature compensation accuracy better than 0.5%5.Data backup and restore6. Strong capability for anti-disturbance: Leading military-grade hardware and software anti-disturbance technology.7.Excellent price-performance ratio: good performance with heading circuit board provides economical solutions.8.HART communication protocolTechnical Parameters - Diezoresistive HART Circuit Board:Supply powerDC12-32V (DC 24V is suggested)Matching sensorstandard diffused silicon, piezoresistive ceramic, single crystal silicon and level sensorsSampling 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 displayingOutput 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), electrical isolationRange ratio100:01Circuit protection Measurement surge current protection, Reverse Power ProtectionCircuit design Intrinsic safetyIsolation range>200MCommunication ProtocolHARTAdjusting methodby buttons on LCD head,  program on pc or communicator, communicatorDimensions OD=61mm, Mounting hole pitch=55.14mm (suited for pressure and level 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.
