GWH400 Intrinsically Safe Infrared Temperature Sensor

wide measuring range, high accuracy, quick response, compatible with various kinds of breaker, non contact monitoring.

Application

This product forms a new generation of intelligent infrared temperature sensors, which is domestically initiated, integrating on optical, mechanical and electronic technologies. Working together with various kinds of breakers and monitoring systems, it can conduct a non-contact and continuous temperature monitoring for coal bed self-combustion as well as hot faults of various kinds of electrical devices under pit. Its functions and characteristics are the coaxial laser collimation, on spot display, sound & light alarm, long-distance signal transmission, and it is convenient to operate.
