8 bytes total:
Bytes 1-4: Object temperature as floating point
Bytes 5-8: Ambient temperature as floating point
CAN ID range
ID can be set between 0 and 255 as a 4-byte unsigned integer
Adjustable from 0.2 to 1.0 as a 4-byte floating point
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.
Sensors may be used at longer distances than the above diagrams show. There is no maximum measurement distance in clean air; this is because Calex sensors detect only the wavelengths of infrared radiation that are not absorbed by the atmosphere.

Electromagnetic Compatibility Standards
EN61326-1, EN61326-2-3 (Electrical Equipment for Measurement, Control and Laboratory Use – EMC Requirements – Industrial)
The PyroCAN measures the temperature of a surface and transmits it via CAN Bus using the Raw CAN protocol.
The sensor can be connected to a network with more PyroCAN sensors and other types of CAN device. A configurable CAN ID allows it to be connected easily to an existing network.
Adjustable emissivity allows a variety of materials to be measured with high accuracy and repeatability. For assistance on obtaining accurate results in your application please contact Calex.
Multiple sensors can be mounted in various locations around a vehicle during testing, to monitor the surface temperatures of engine blocks, suspension parts, belts and exhausts.
Industrial and agricultural vehicles
The PyroCAN allows temperature monitoring on vehicles throughout industry and agriculture. The process temperature can be accurately monitored without contact, and parts of the vehicle can be monitored with the same sensor.
Each sensor is fitted with a 1-metre cable as standard. Longer lengths are available to order, or you can extend the cable using terminal blocks.
The PyroCAN is available worldwide from our network of distributors. Contact Calex for to find out where you can order the PyroCAN in your country.
