The IR-23.1 spark sensor with 3-arm optical fiber detects sparks and flames in closed systems. The infrared spark sensor is well suited for sparks and flames with temperatures > 800°C. The maximum of its spectral sensitivity is at about 830 nm.
This ATEX certified device is designed for installation in parts of the system in which it is completely dark and where no extraneous light is expected. Daylight contains infrared portions which the sensor will respond to and
