The explosive and hazardous gases such as biogas and hydrogen are produced in city pipe galleries, utility tunnels, chemical storage warehouses and other industrial application scenarios, so it is very important to monitor the temperature and humidity in such scenarios.
TH160EX-L Intrinsically Safe Explosion-Proof Environmental Monitoring Temperature and Humidity Transmitter is specifically developed for this application. The sensitive elements of TH160EX-L adopt high molecular film humidity-sensitive capacitor and PT1000 temperature-sensitive resistor, which use special breathable coating and circuit injection packaging process, to ensure that the probe can withstand dust pollution and high humidity condensation environment, while having good long-term stability and precision.
