Data SheetThe PyroCV is a simple, robust infrared temperature sensor with CAN communications or a voltage output, tested to EMC standards for construction machinery.
No complicated setup is required – just connect a temperature indicator and power supply, and instantly start taking measurements.

Field of View Diagrams
Please note: The given measured spot size contains 90% of the energy detected by the sensor. We normally recommend the target is at least twice as large as the given measured spot for maximum accuracy.
Sensor can measure at longer distances than shown, with a larger measured spot size; this is because the PyroCV detects only the wavelengths of infrared radiation that are not absorbed by the atmosphere.

Electromagnetic Compatibility (EMC)*
ISO 13766-1
*The PyroCV has been tested for load dump conditions in accordance with ISO16750-2 (clamped load dump). Compliance with ISO 13766-1 assumes installation in electrical systems providing equivalent load dump suppression. Protection against unclamped load dump must be ensured at system level.
