Patol 5610 Heat Sensor – Infrared Transit Heat Sensor (Patol 5000)

Patol 5610 Heat Sensor
Patol 5610 infrared conveyor heat detector provides early warning heat sensor and can trigger at temperatures as low as 100°C and is specifically designed for hazardous areas and is IECEx / ATEX approved for Zones 1, 2 & 21, 22.
The Patol 5620 incorporates a series of user programmable SIL switches with option selections including detector sensitivity settings, auto/manual reset sequence selection and single / coincidence voting from the two individual internal detectors for the alarm trip and shutdown outputs.
The unit can be used in two principle operating modes. Either relay mode, with its own 24 Vdc power supply or in low power mode (as shown below), see datasheet for further details
Typical applications for the Patol 5610 heat detector include:
- Conveyors
- Biomass
- Drying Lines
- Waste Recycling Conveyors
- Food Processing
- Production Lines
