JTH-CH381Ex point type infrared flame detector (three wavelengths)

 1. Performance characteristics of JTH-CH381Ex point infrared flame detector

Immunity to electromagnetic radiation, sunlight and background thermal radiation.

3.8uM, 4.4uM, 5.0-11.0uM three wavelength detection reduces false explosion rate.

Standard RS485 interface based on Modbus (RTU) protocol and 4~20mA output, alarm relay output.

It can be used in conjunction with the alarm controller, PLC, DCS and other systems produced by Xihe Caiqiao.

It adopts single-chip microcomputer processing system, which has strong stability and anti-interference ability and low power consumption.

Reverse protection function.
