Patol 710-5812 High Temp Heat & Flame Sensor 5812 Narrow Band Stainless Steel c/w Mounting Bracket

Patol 710-5812 High Temp Heat & Flame Sensor 5812 Narrow Band Stainless Steel (Compressed Air Purging) comes with Mounting Bracket

The 5812 High Temperature Transit Flame Sensor monitors high temperature materials (up to 240° on highest sensitivity), being transported on conveyor systems, 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 4.2-4.7m. 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.

Air purging from a compressed air feed is used to maintain a positive air pressure in conjunction with an air knife to prevent dust settling on the sensor window. The air supply is monitored by a pressure switch which on air failure is signalled as a fault status.

The controller is directly connected to the sensor. A series of user programmable DIL switches allows option selection including detector sensitivity settings, auto/manual reset sequence selection and single / coincidence voting from the four individual internal detection channels for the alarm trip and 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.
