I. Overview :
     SMT106-YX intelligent explosion-proof electromechanical integrated temperature transmitter (hereinafter referred to as temperature transmitter) consists of a temperature sensor and signal converter, the signal converter is installed in the explosion-proof junction box, the signal detected by the temperature sensor is directly converted into 4 to 20mA current output. The structure is simple, installation, use, and maintenance are convenient. It is a new generation of intelligent temperature detection and control instruments. It is well received by designers and users. At present, it has been widely used in petroleum, chemical, metallurgy, power station, light industry and other departments. It is used together with regulators, recording instruments, and computers to form various measurement and control systems. The explosion-proof temperature transmitter has passed the test of national-level instrumentation explosion-proof safety supervision and inspection station, and can be used in explosive gas environment.

2. the main features:
1. Two-wire transmission. The two conductors fed by the signal converter also transmit the output signal.
2. Output constant current signal (4 ~ 20mA). Strong anti-interference ability and good remote transmission performance.
3. The signal converter has the advantages of anti-vibration, anti-corrosion and anti-humidity. It can be used in places with poor conditions.
4. The sensor signal is directly converted into a 4-20mA current output by the signal converter, and the signal is transmitted by an ordinary cable, eliminating the need for expensive compensation wires.
5. The temperature transmitter comes with a liquid crystal display, which not only outputs a current signal of 4 to 20 mA, but also reads the measured temperature at the temperature measurement site, bringing great convenience to the operator.
