Typical Applications
The PyroUSB’s choice of measurement wavelengths allows it to be used in a wide range of industrial applications.
Steel
The short-wavelength PUA2 provides a more accurate reading on reflective metal surfaces, such as iron and steel, than longer-wavelength sensors. Applications include general steel strip temperature measurements at low temperatures, steel temperature measurement before the reheat furnace and temperature at the coiler on the hot rolling mill
Extrusion, Forging and Casting
PUA2 models are ideal for measuring the temperature of steel dies and workpieces in extrusion, forging and casting applications
Food
Measure the temperature of hot food products inside glass containers from 45°C to 300°C using PyroUSB PUA2 models. The pyrometer measures through the glass; readings can be taken on-line without interrupting production.
Other applications include tunnel pasteuriser temperature monitoring, and temperature of bare stainless steel surfaces on food manufacturing machinery, such as hot rollers and conveyors
Brake testing
PyroUSB PUA2 sensors allow non-contact measurement of ceramic, carbon, iron and steel brake disc temperatures between 45°C and 2000°C on brake test rigs
Wind power
PUA2 models can monitor brake disc surface temperature in wind turbines, to help warn of overheating and optimise cooling cycles. PUA8 models measure non-reflective parts of the turbine, such as gearbox and bearing housings. Non-contact infrared sensors can monitor the temperature of vibrating parts while being isolated completely from vibration.
Bearings, gearboxes and shafts
Non-contact temperature measurement of bare steel surfaces: the PyroUSB PUA2 is less susceptible than long-wavelength sensors to errors caused by reflections
Furnaces and ovens
The high-temperature capability of the PyroUSB PUA2 is ideal for measuring the temperature of hot objects inside furnaces and ovens, including steel mill heat treatment furnaces.
Pipe coating
Furnace-heated or induction heated pipe temperature measurement, at the preheat stage, before coating (using model PUA2)
Paper, Print and Converting
PUA2 models: Monitoring of the surface temperature of hot bare steel rollers, such as steam-heated dryer cylinder temperature in paper manufacturing.
PUA8 models: Accurate measurement of the paper temperature is easy, even at very low temperatures.
Temperature readings may be used for control and alarm.
Measuring Hot Food Product Temperature Through Glass Jars
The new PyroUSB 2.2 Series of infrared temperature sensors is ideal for measuring the temperature of hot food products through glass containers.
After a food product is filled into glass jars, samples are usually taken from the production line and manually probed to check the product temperature. The PyroUSB 2.2 now makes it possible to check product temperatures without taking samples from the production line, and without even touching the samples at all.
