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.
2. Product Features
(1) Long temperature measurement distance, high sensitivity, high
measurement accuracy, fast response speed, and accurate positioning
(2) Intuitive display of full-line temperature data, historical
temperature data curves, and curve trends
(3) Low power consumption, fully embedded system with independent
intellectual property rights
(4) Not affected by strong electromagnetic interference in
high-voltage environments, inherently lightning-proof, and suitable
for use in high-voltage environments
(5) Robust equipment, stable performance, reliable system, simple
installation, and easy maintenance
3. Application
(1) Mainly used for temperature monitoring and temperature anomaly
alarms at critical points such as coal mine tunnels and working
faces, electromechanical equipment, power cables, coal conveyor
bridges, belt conveyors, raw coal silos, and explosives storage
facilities
(2) Locating temperature anomaly areas in abandoned mine areas
where fires may occur
