JT3051TS Diezoresistive Silicon Intelligent Circuit Board
Introduction:
JT3051TS Diezoresistive Silicon 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:
1. Easy adjusting by buttons: on-site span changing by LCD module buttons free from standard pressure source
2. High accuracy: for intelligent board, AD accuracy > 20 bits, DA accuracy > 16 bits;
3. Electrical isolation: > 1500VDC
4. Good stability: Linearity better than 0.05% (with sensors), temperature compensation accuracy better than 0.5%
5. Data backup and restore
6. 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.
