Infrared temperature sensors

There are a host of industrial applications where temperature of a component or device needs to be monitored. And, in many of these applications, it’s not feasible to use a direct contact method of temperature measurement. In these situations infrared temperature sensors come to the fore.

Infrared temperature sensors measure the ambient infrared energy that is emitted by a component or machine. Because infrared temperature sensors are a non contact type of sensor, there is no wear on the sensing element and hence the sensor will not be damaged by out-of-range ambient temperatures or by the process application itself.

Cost-effective temperature measurement

One of the main benefits of the non-contact type of infrared temperature sensors is that they are extremely cost-effective. Some infrared temperature sensors also come with a laser spot sight, which can be used to accurately position the measurement target, which can be essential if the sensor is mounted some distance from the target. And for critical alignment of the sensor to measure small objects

Some infrared temperature sensors can be hand held and used by engineers carrying out preventative maintenance duties. The maintenance engineers can simply point the device at a component that needs its temperature recording and log the results. Some other infrared temperature measuring sensors are application specific and are mounted in position permanently. Accurate temperature measurement means checks on temperature can be continually taken and used as part of a process controlled application, so if temperature rises above setpoint levels, the process can be shut down automatically.
