Infrared Thermometers, Temperature …

2009-5-6 · Infrared thermometers measure temperature using blackbody radiation (generally infrared) emitted from objects. They are sometimes called laser thermometers if a laser is used to help aim the thermometer, or non-contact thermometers to describe the device’s ability to measure temperature …

Infrared Temperature Sensor: what is it and how does it work?

Sep 14, 2009· An infrared temperature sensor used in contact-type instruments include thermocouples, resistance temperature detectors (RTDs), thermistors, and semiconductor temperature sensors. Since contact sensors measure their own temperature they require physical contact with the measured object to bring the sensor body to the object’s temperature.

Infrared Melt Temperature Measurement of Single Screw ...

An infrared temperature sensor has been used to provide real time quantification of the thermal homogeneity of polymer extrusion. The non-intrusive sensor was located in the barrel of a single screw extruder, positioned such that it provided a measurement of melt temperature in the channel of the metering section of the extruder screw.

Infrared Temperature Instruments - Measurement Principles

Jan 20, 2020· To make an accurate infrared temperature measurement, you need to set the emissivity value of the sensor to match the emissivity of the object you are measuring. This is most often done by making a contact measurement (once) and then setting the emissivity so that the infrared sensor temperature matches the contact measurement.
