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
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.
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.
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.
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.
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.
