CAN Protocol Specifications
Bytes 1-4: Object temperature as floating point
Bytes 5-8: Ambient temperature as floating point
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.
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 air purge collar is used to keep dust, fumes, moisture and other contaminants away from the lens. Air flows into the fitting on the side and out of the aperture at the front.
The L-shaped fixed mounting bracket offers a rigid support for the sensor and allows fine rotational adjustment about one axis.
The adjustable mounting bracket consists of a fixed mounting bracket plus another L-shaped bracket. When assembled as shown, the adjustable mounting bracket offers a rigid support for the sensor and allows fine two-axis adjustment.
The air/water cooled housing allows the sensor to withstand ambient temperatures above the normal 70°C limit. Depending on the degree of cooling required, air or water may be used as the cooling fluid. To prevent condensation forming on the lens, an air purge collar is included with this item. The air/water cooled housing must be ordered with the sensor and cannot be fitted by the user.
The Laser Sighting Tool screws onto the front of the sensor during installation and shows precisely where the sensor is aiming. Once the sensor has been aimed at the centre of the target and locked in position, the Laser Sighting Tool can be removed. The laser is operated via a latching push button on the front of the tool.
The Dual Laser Sighting Bracket is a sturdy mount for the sensor and provides continuous target sighting while measurements are being taken. Two parallel lasers indicate the centre of the measured spot and are controlled by a remote switch on the electronics module.
When fitted over the lens of the sensor, the protective plastic window in stainless steel holder provides mechanical protection and helps retain fragments of lens in case of damage. Adjust the sensor’s emissivity setting to compensate for the presence of the window for maximum accuracy. This accessory is ideal for the food and pharmaceutical industries.
