The PyroCouple is an ideal general-purpose sensor for a huge range of applications. For example, some typical uses include:

Typical Applications

Food
For food temperature measurement, a fixed-emissivity sensor such as the PyroCouple is usually suitable. A range of controllers and indicators is also available. A famous manufacturer uses the PyroCouple to measure chocolate temperature before the mould as it is heated in temperature controlled “kettles”, and the temperature of toffee webs as they leave cooling drums.
Asphalt
Measuring tarmac road surface temperature when paving and in infrared pothole repair. Asphalt temperature measurement after heating and in discharge chutes.
Paper
Temperature and moisture monitoring and control in corrugated board manufacturing, paper drying and condition monitoring.
Plastics
Thermoforming temperature control and monitoring.
Power industry
Monitoring the temperature of painted surfaces in switchgear.
Microwave dryers
In food, paper, pharmaceutical and textile industries, among others, infrared temperature sensors can be positioned outside the microwave field and aimed at the object being dried.
Infrared curing of paint and adhesives
If the emissivity of the target is high, the reflection of the infrared curing heater does not significantly influence the measurement, and the PyroCouple gives good results.
Condition monitoring
e.g. painted bearing housings, driveshafts, rollers and gearboxes.
Leaf temperature
e.g. in greenhouses.
Tyre manufacturing
Measuring the “green” tyre temperature before tread curing to compensate for seasonal temperature variation.
Gas cylinder filling
Monitoring the temperature of each cylinder on a filling rig to improve repeatability in the filled volume and improve filling efficiency.
