The WS-M8000A is a flame detection module based on the infrared principle. It utilizes a pyroelectric sensor and a high-performance microprocessor, and is designed as a flame detection module through the combination of different sensors.

It is equipped with a high-speed single-chip microcomputer, which collects the sensor signals and uses a reliable and efficient algorithm to determine the presence of a fire. With a passive relay output, it is compatible with a variety of systems and is relatively accurate in identifying flames generated by hydrocarbon substances.

Application

It is mainly applied in aerospace industry, storage facilities, printing industry, paint manufacturing, pharmaceutical industry, machinery and automotive manufacturing industry, petroleum and petrochemical industry, etc.

Features

Adopts sensors with a large field of view angle, high detection rate, and low microphone effect.
Establishes a data model by combining various combustible substances, resulting in a low false alarm rate.
The high-speed single-chip microcomputer enables rapid response and accurate identification.
