TH160EX-N Nuclear Power Industry Intrinsically Safe Explosion-Proof Multi-Parameter Temperature and Humidity Transmitter

In nuclear power and other demanding industrial fields, it is necessary to monitor the temperature and humidity parameters of certain explosive gas medias. TH160EX-N is an industrial-grade intrinsically safe explosion-proof multi-parameter temperature and humidity transmitter with explosion-proof class Ex ia II C T6 Ga. The transmitter and probe can be installed in the danger zone, and the probe can be installed in the 0 zone of danger zone. In addition to measuring temperature and humidity parameters, it can be used to measure the dew point, frost point, enthalpy value, partial pressure of water vapor, absolute humidity, mixing ratio and other gas humidity parameters. At the same time, parameters such as dissolved water activity and absolute water content in dangerous oil products can also be measured. Output signal 4 ... 20mA or RS485 is optional.

The shell and probe materials of the TH160EX-N transmitter are made of 316 stainless steel which is firm and durable, Probe temperature resistance range is -70 ... 190 ° C, with pressure resistance up to 20Bar, suitable for most industrial site application conditions. TH160EX-N has passed anti-seismic, irradiation aging and other related nuclear grade type tests, and the overall irradiation tolerance dose can reach 350Gy.
