MD-TA Integrated Temperature Transmitter/Thermowell Transmitter

Short Description:

MD-TA compact temperature transmitter is an integrated ultra-stable temperature transmitter with a built-in imported PT100 high-precision temperature sensor. It adopts a compact circuit with input and output isolation.

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   

The probe and housing of the product are made of 316L stainless steel, the structure is laser welded, and the connection line adopts IP67 waterproof aviation plug-in line, which greatly guarantees the long-term stability and reliability of the product.
