IR-11.1 / IR-13.1
IR spark detector
The infrared spark detectors IR-11.1 (1-arm fiber optic cable) and IR-13.1 (3-arm fiber optic cable) detect sparks and flames in closed, potentially explosive systems. The maximum of their spectral sensitivity is around 830 nm. The devices are well suited for sparks and flames with temperatures > 800°C. The devices are designed for installation in parts of the system where it is completely dark and where no extraneous light is to be expected. Daylight contains infrared components that trigger the devices and can therefore cause false triggering.
IR-11.1 and IR-13.1 are used, for example, in electronic spark extinguishing systems with monitoring devices for the early detection of fires and explosions. They are also used wherever flammable or smoldering materials are transported mechanically or pneumatically and there is a risk of fire or explosion.
The detectors have relay outputs for faults and alarms and internal monitoring of the operating voltage.
