Product Description
JT3051DH Capacitive HART Transmitter Circuit Board + LCD DisplayJT3051TH 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 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.
8.HART communication protocol
