Industial Digital or Analog Diezoresistive Circuit Board with LCD Display

JT3051 Diezoresistive Intelligent Circuit BoardJT3051 Diezoresistive Intelligent Circuit Board replaced the original 4~20mA analog board. With the main body of Microcontrollers CPU, JT3051 is capable to do logical operation and programming. It combines analog and digital circuit in one machine, so is able to output analog signal as well as digital signal. Parameters configuration and compensation of transmitters can be done by buttons on LCD module and internal debugging program. JT3051 provides constant current excitation way for sensors, supporting standard diffused silicon, piezoresistive ceramic, single crystal silicon and level sensors. It is suited for 3051 housing.Features - Diffused Silicon 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 bits3. Electrical isolation: > 1500VDC4. Good stability: The complete machine linearity better than 0.2%, temperature5. Data backup and restore6.  Strong capability for anti-disturbance: Leading military-grade hardware and software anti-disturbance technology7. Excellent price-performance ratio: good performance with heading circuit board provides economical solutionsTechnical Parameters - Diffused Silicon 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)Range ratio10:01Circuit protection Measurement surge current protection, Reverse Power ProtectionCircuit design Intrinsic safetyIsolation range>200MCommunication ProtocolPrivate protocolAdjusting methodby buttons on LCD head,  program on pc or 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, output features, changing damping time, currant fixing, write-protection,factory reset and zero clearingWhy choose WNK?1.
