Product Description

JTST Small Size Intelligent Circuit Board

JTST Small Size Intelligent Circuit Board with LED replaced the original 4~20mA analog board. With the main body of Microcontrollers CPU, JTST 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 can be done by adjusting programs to approve accuracy grade of transmitters. JT2088 supports standard diffused silicon and piezoresistive ceramic pressure sensors. It is suited for small size columnar pressure transmitters and input type level transmitters.






Features - Small Size Intelligent Circuit Board

1. Two wires working mode provides sensors with two exciting ways - constant current and constant voltage.
2. Calibrating as per full scale realizes bulk production and assures aging test time.
3. Easy to do temperature compensation, under -20~70ºC the complete machine accuracy better than 0.5%
4. Three points calibrating, complete machine accuracy better than 0.2%. Multi-point calibrating is available as required.
5. AD accuracy > 20 bits, DA accuracy > 16 bits;
6. Multi-functions as temperature compensation, small signal wipes off, zero clearing and etc.
