MD-TB explosion-proof temperature transmitter
Explosion proof high-precision 316L adjustable range temperature transmitter
Product details

MD-TB integrated temperature transmitter is a dip switch type intelligent temperature transmitter with imported PT100 high-precision built-inThe temperature sensor is equipped with a digital dip switch type intelligent temperature transmitter circuit board and an input/output isolation design.


The temperature transmitter adopts a circuit design that is lightning resistant and resistant to electrical fast transient (pulse group) interference. Equipped with lightning protection function,The lightning protection index has reached the level of induction lightning (≤ Ø 4000V) for 5 consecutive times without causing damage to the equipment, in order to protect the connected equipment from damage; inputBoth the terminal and the output terminal have the ability to resist electrical fast transient (pulse group) interference up to 4000V. This product can effectively protect against sensory disturbancesStart stop, line faults, switching actions, operation of frequency conversion equipment, and on-site construction of high-power equipment within lightning or power supply systemsDamage caused by working hours, welding machines, and other reasons.


Users only need a screwdriver to transfer the dip switch and adjust the range of the temperature transmitter on site, shortening itOperation time, simple operation, easy to use


☆ Adopting explosion-proof junction box, structurally fastened, and compact in size

☆ Dial switch design, multiple temperature ranges can be set

☆ Circuit design with lightning protection and resistance to fast transient (pulse group) interference

☆ IP 65 waterproof design

4-20mA output, strong anti-interference design

Range -50~400 ℃(4-20mA output)

Users can adjust the range by themselves through the dip switch (e.g. 0-50 ℃)/0-100℃/0-150℃/0-200℃/0-250℃/0-300℃/0-350℃/0-400℃
