Non-contact temperature sensor.

The new PyroNFC-K from Calex Electronics is a new miniature infrared temperature sensor that is quick and easy to install in place of a traditional thermocouple probe.

Industrial processes have used thermocouples for temperature measurement for more than 100 years, but non-contact sensors are now increasingly used in their place thanks to proven, modern infrared measurement technology. Traditional contact probes have several drawbacks such as a slow response time, as well as susceptibility to mechanical failure and vibration, which can all be overcome simply by switching to infrared pyrometers.

The fully-configurable PyroNFC-K has a simulated thermocouple output, making it easier than ever to start using IR temperature sensors in place of thermocouples. Its side-entry cable and length of just 29 mm make it easy to mount in confined spaces.

The pyrometer works by measuring the amount of infrared radiation that a surface emits, and converting that into a meaningful temperature reading within 0.125 seconds. The output works just like the old Type K thermocouple that it replaces, and is connected in the same way to the same instrumentation with no need to re-configure it. Then all the sensor needs to start measuring is a supply of 6 to 28 V DC.

Measurements are highly repeatable, within 0.5% or 0.5°C, helping to ensure consistent product quality in manufacturing processes.

Non-reflective non-metals are measured easily and accurately straight out of the box, and painted metals are also no problem. The sensor can be configured for emissivity setting, averaging, peak or valley hold processing, and reflected energy compensation, without even connecting the power, via the free Android app for NFC-enabled phones. If the sensor is powered, the temperature reading is shown continuously while the phone is held against it.

The included open drain alarm output (standard on all models) can be used simultaneously with the temperature output, and a version with a linear voltage output is also available.
