WR-202 Armored Temperature Sensor

WR-202 Armored Temperature SensorThe use of imported temperature measuring components, packaging technology, and sophisticated assembly processes ensure the quality and performance of the product. This series of temperature sensors has many advantages, such as fast thermal response time, strong heat resistance, high pressure resistance, earthquake resistance, multiple temperature models to choose from, and diversified installation methods. It transmits the sensed temperature levels through connecting wires to display instruments, record instruments, electronic regulators, and other instruments to read temperature readings.

WR-202 Armored Temperature SensorApplication Description:

In chemical plants, various flammable and explosive chemical gases are often present on the production site. Using ordinary thermocouples is very unsafe and can easily cause environmental gas explosions. Therefore, explosion-proof thermocouples must be used as temperature measuring instruments in these situations.
