Description
Patol 5730 Infra-Red High Temperature Heat Sensor 115vAC
The 5730 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 4.2-4.7?m. 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 mains operated Air Purged Blower (APB) air feed is used to maintain a positive air pressure in the sensor enclosure, and ensures the prevention of 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 5730 incorporates within the unit a series of user programmable DIL switches. 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 aux. fault input & common fault output contact.
