Patol, 722-110, ATEX IECEx High Temperature Transit Flame Sensor

Patol, 722-110, ATEX IECEx High Temperature Transit Flame Sensor

The 5710 High Temperature Transit Flame Sensor monitors high temperature materials (up to 240° on highest sensitivity), being transported on conveyor systems at speeds of between 0.5 and 6m/s, and triggers as the material reaches the ember or flame condition.

The sensor employs enhanced infra-red monitoring technology that analysis the levels of IR emission in the narrow band of 4.2-4.7μm. As the sensor is tuned to this band it is “solar blind” meaning the “background” and “transient” IR spectra are discriminated. This provides enhanced false alarm immunity.

The 5710 is specifically designed for hazardous areas and is IECEx / ATEX approved for Zones 1, 2 & 21, 22.

Air purging from a compressed air feed is used to maintain a lens cleaning system that ensures the prevention of dust settling on the sensor window.

The 5710 incorporates within the unit a user programmable SIL switch. Option selection includes detector sensitivity settings, auto/manual reset  sequence selection and single/coincidence voting from the two individual internal detectors for the alarm trip shutdown outputs.

The sensor air pressure and signal cable connections are fault monitored and fail safe. The controller incorporates an auxiliary fault input and common fault output contact.
