JT3051DS Capacitive Intelligent Circuit Board replaced the original 4~20mA analog board. With the main body of Microcontrollers CPU, JT3051DS 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 circuit board is specially designed for capacitive differential pressure sensor, and is suited for JT3051DS housing.
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: The complete machine linearity better than 0.2%, temperature
4. Data backup and restore
5. Strong capability for anti-disturbance: Leading military-grade hardware and software anti-disturbance technology.
