Product Description

JT3051CH Capacitive HART Circuit Board

 

JT3051CH Capacitive HART Circuit Board uses advanced completely isolation technology. The power side is islolated by transformer, signal side isolated by opticalcoupler to make transmitters with good anti-interface, thus ensure high realiability and stability. Parameters configuration and compensation of transmitters can be done by buttons, HART communicators or HART configuration programs, improving precise level and accuracy of transmitters. JT3051CH matches capacitive differential pressure sensor and is suited for 3051 housing.

Features - JT3051CH Capacitive HART Circuit Board:
 

1.Easy adjusting by buttons: on-site span changing by LCD module buttons free from standard pressure source; for headless type, PV reset and span correction with pressure source done by buttons on mainboard 

2.High accuracy: for intelligent board, AD accuracy > 20 bits, DA accuracy > 16 bits;

3.Good stability: Linearity better than 0.1%, temperature conpensation accuracy better than 0.5%

4.Data backup and restore

5.Eletrical isolation: >1500VDC

6.Communication protocol:4~20mA output with HART protocol digital communication (two wires) 

7. Adjusting method: through communicator or telemanagement via PC configuration adjusting program
