PyroUSB non-contact infrared temperature sensor

The PyroUSB non-contact infrared temperature sensor connects directly to a PC via a USB cable (included) and operates without the need for any additional hardware interface or power supply.

The CalexSoft software (also included) is simple to install and requires no specialist knowledge to set up and use. It displays temperature in numerical format and on a simulated scrolling chart. Users can set the temperature range and emissivity, compensate for reflected energy, apply filtering to fluctuating temperatures and use peak or valley-hold processing to measure hot or cold objects on conveyors. The software may also be used to record measurements at any interval from one second to one week and preprogrammed to start and finish at any time or date.

Audible/visual alarms can be set to warn users that the temperature is either too high or too low. The built-in OPC server interface allows communication between the sensor and any other equipment with OPC client capabilities, making systems integration simple.

In addition to the USB interface, the sensor is equipped with a 2-wire, 4 to 20 mA output, which is linear with temperature. This output can be connected at the same time as the USB interface or independently. The PyroUSB sensor is capable of measuring temperatures accurately and repeatably from -40 up to 1000°C. If a smaller range is required this can be set using the CalexSoft software.

The sensor itself is 106 mm long by 18 mm diameter and made of polished stainless steel, sealed to IP65, making it suitable for food and pharmaceutical applications.

If the sensor is required to operate in a very high or low ambient temperature (less than 0 or more than 70°C) it can be ordered with a water/air-cooled jacket built around it. The temperature inside the sensor can also be monitored from the PC to make sure it doesn’t exceed the ambient limits.
