IR-23.1
IR spark detector
The IR-23.1 spark detector 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
IR-23.1 is used, for example, in electronic spark extinguishing systems with monitoring devices for the early detection of fires or explosions.
It is also used wherever flammable or smoldering materials are transported mechanically or pneumatically and there is a risk of fire or explosion.
The detector has relay outputs for faults and alarms, an integrated test device and internal monitoring of the operating voltage.
