Non-contact infrared temperature sensor

The PyroUSB sensor can be connected directly to a PC via a USB cable (included) and operates without the need for any additional hardware interface or power supply. The sensor is also equipped with a 4-20 mA output, which has a linear output with temperature.

The PyroUSB sensor is capable of measuring temperatures accurately and repeatably from -40 to 1000 °C. If a smaller range is required, this can be set using the CalexSoft software.

The sensor is 106 mm long by 25 mm diameter and made of polished stainless steel, sealed to IP65, making it suitable for food and pharmaceutical applications. There are three distance/spot size options, mounting brackets and water/air-cooled jackets for hot and dusty environments. For paper and textile mills, an air purge collar can be fitted to keep the lens clean.

The CalexSoft software 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 1 s to 1 week and can be pre-programmed to start and finish at any time or date. Audible/visual alarms can be set, and the built-in OPC server allows communication between the sensor and any other equipment with OPC client capabilities.
