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
