GCT01DX series transmission board is a network-based intelligent transmission board with RS485 interface. Through the highly integrated circuit with microprocessor as the core, it reliably realizes the collection and processing of pressure and temperature signals and RS485 communication output. The communication interface realizes full digital debugging and calibration. It is especially suitable for low-cost and compact product design with diffused silicon, ceramic, strain type pressure sensor or RTD temperature sensor. It has been used in many customer sites for a long time, and provides relevant testing and calibration software to facilitate production testing. ("P" for pressure, "T" for temperature.)
