USB configurable infrared temperature sensors

June 2018 Sensors & Transducers

ASSTech markets the British-made Calex range of pyrometers and now offers the new USB configurable infrared temperature sensors with 4-20 mA output. Temperatures are measured accurately and consistently from -40 to 2000°C with an outstanding response time of 200 ms. The devices are compatible with almost any indicator, controller, recorder or data logger, without the need for special interfacing or signal conditioning.

A choice of measurement wavelengths is available to suit a range of applications

The general purpose PUA8 models can measure from -40 to 1000°C. They are suitable for measuring high emissivity materials such as paper, thick plastics, food, pharmaceuticals, rubber, asphalt and painted surfaces. These models are capable of measuring very low temperatures and are ideal for sub-zero measurements in the food, logistics and storage industries.

Short wavelength models (PUA2) have a choice of temperature ranges from 45 to 2000°C. They provide a more accurate reading when measuring low emissivity materials such as many reflective metals. They are also capable of measuring through glass viewports. Glass PUA5 models operate in ranges between 50 to 1650°C They are filtered at a wavelength where glass is least reflective, making these an ideal pyrometer for glass surface measurement. A USB cable and Windows software is included. All data is transmitted via Modbus so it is also easy to configure and read temperatures from the sensor using third-party software. The USB cable has an IP65 connector and housing is stainless steel.
