The TT series temperature transmitters are designed for high-precision temperature measurement and control in advanced equipment. Compatible with thermistor temperature sensors, they feature an RS485 communication interface supporting the standard Modbus RTU protocol. The transmitter adopts an isolated design between the communication and measurement modules, ensuring strong anti-interference capability. Equipped with a 24-bit high-precision AD converter and low-drift reference components, it delivers excellent long-term stability. Parameters such as configuration, calibration, and sensor characteristics are user-programmable.
