Small Size Smart Circuit Board with LED Display

Product Description

JTST-LED Small Size Intelligent Transmitter Module

JTST-LED, with the main body of Microcontrollers CPU, is able 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 as per customer's requirement. Parameters configuration and compensation can be done by adjusting programs to approve accuracy grade of transmitters. Adopting HIRSCHMANN connector, JTST-LED is transmitter, display, buttons and communication in one and same device, and can be directly connected with piezoresistive silicon sensor or ceramic piezoresistive sensor to be high performance pressure transmitter. Thus it is more cost-efficient
Production Line




Features - Small Size Intelligent Circuit Board with LED Display

1. Four-bite high light LED displaying
2. Two wires working mode provides sensors with two exciting ways - constant current and constant voltage.
3. Calibrating as per full scale realizes bulk production and assures aging test time.
4. Easy to do temperature compensation, the complete machine accuracy is better than 0.5% under -30~70ºC
5. Three points calibrating, complete machine accuracy better than 0.2%. Multi-point calibrating is available as required.
6. AD accuracy > 20 bits, DA accuracy > 16 bits;
7. Multi-functions as temperature compensation, small signal wipes off, zero clearing and etc.
8. On-site adjusting can be done by bottons
9. HIRSCHMANN connection
