The MD-TB explosion-proof temperature transmitter is a dial switch intelligent temperature transmitter, Built-in imported PT100 high-precision temperature sensor, equipped with digital DIP switch intelligent temperature transmitter circuit board, input and output isolation design.
This temperature transmitter adopts the circuit design of lighting protection and anti-electrical fast transient (pulse group) interference. It has the lighting protection function which the lightning protection index reaches the induction lightning(≤iA4000V) for 5 times continuously without damage to the equipment. Input and output are capable of resisting iA4000V interference from electrical fast transients (pulse group). This product can effectively protect the damage due to induction lightning or start and stop of the high power facility in the power supply system, circuit fault, the operation of inverter equipment and electric welder in the construction site etc. This product can effectively prevent damage caused by induction lightning or start-stop of high-power equipment in the power supply system, line failures, switching operations, operation of frequency conversion equipment, and welding machines during field construction
Users only need a screwdriver to dial the DIP switch and adjust the range of the temperature transmitter in the field, which greatly shortens the operating time, simple operation and easy to use.
