Most infrared temperature sensors have an adjustable emissivity setting. Emissivity is a measure of how effectively a surface emits infrared radiation. For an accurate temperature reading, the emissivity setting of the sensor must match the emissivity of the surface being measured. For non-reflective non-metals and painted surfaces, the emissivity is usually about 0.95. This is the … Continue reading How to Adjust the Emissivity Setting of an Infrared Temperature Sensor

PyroCouple infrared temperature sensor with air or water cooled jacket

Non-contact temperature measurement is now possible in areas of high ambient temperature with no need for sensor cooling using air or water. This brings several benefits, including cost reduction, better safety, and improved product quality in manufacturing processes.

Technical advice from Calex Electronics on choosing a suitable infrared temperature sensor to measure small targets.  

Smallest pyrometer from Calex - the PyroNFC

The new PyroNFC-K from Calex Electronics is a fully-configurable infrared temperature sensor that can be installed in place of a thermocouple probe quickly and easily.

Complete PyroMiniBus temperature monitoring and logging system with 6 sensors, junction box and touch screen display module

The PM180 allows a group of infrared temperature sensors to be connected to a Modbus Master as a single device. Here’s how to configure the Modbus Master to communicate with each of the sensors.

Thick plastics are non-reflective to infrared radiation, so they are usually easy to measure with infrared temperature sensors. Thin plastic films can transmit IR, and a specialised sensor is sometimes required for accurate results. Calex has suitable pyrometers for measuring plastics in many industrial applications. Thermoforming Temperature measurement in thermoforming is easy and straightforward with non-contact … Continue reading Infrared Temperature Measurement in the Plastics Industry

In this video, Anthony Smith introduces the PyroNFC, the world’s first NFC-compatible infrared temperature sensor. The sensor has configurable voltage and alarm outputs, and is compatible with Android phones with NFC. Watch this video to find out about the main features of the sensor and the app.

The FibreMini fibre optic pyrometer for metals and harsh, high-temperature applications

Measuring the temperature of reflective metals is a challenge. Reflective surfaces, hot furnaces and high ambient temperatures can make it difficult to achieve accurate results with non-contact sensors. The new FibreMini fibre-optic pyrometer from Calex has innovative features that are specialised for accurate measurements in this industry.

High ambient temperature applications for infrared temperature sensors (pyrometers)

How do you measure the temperature of an object without touching it? What kind of sensor should you use? How accurate is the measurement? Learn all this and more with this brief introduction to infrared thermometry.

PyroCube infrared temperature sensor with fast response time and built-in aiming light

If you need a pyrometer with a very small measurement spot size, a very fast response time, or continuous built-in aiming, the PyroCube is ideal. Here are some applications where each of these features can be used.
