Mine Flameproofand Intrinsically Safe Distributed Optical Fibertemperature Measuring Host
1.Product Overview
The ZWX-4Z Mine-Use Explosion-Proof and Intrinsically Safe Distributed Fiber Optic Temperature Measurement Host is a compact, high-precision, multi-channel, continuous distributed fiber optic temperature measurement device independently developed and manufactured by our company. It is capable of continuously measuring the temperature distribution along the fiber optic cable. It features intrinsic safety, real-time online monitoring, a wide temperature measurement range, high measurement accuracy, and resistance to electromagnetic interference. The signal transmission optical cable itself serves as the sensor, enabling real-time online monitoring of temperature changes along the entire auxiliary line, thereby eliminating potential hazards and accidents at their inception. It is widely applied in industries such as mining, power, petroleum, and transportation.
