The PyroUSB’s choice of measurement wavelengths allows it to be used in a wide range of industrial applications.Typical 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.

Applications:

• The PyroNFC is a general-purpose infrared temperature sensor. It measures non-reflective non-metals straight out of the box using default settings.
• The surface temperature of materials including paper, thick plastics, wood and manufactured board, painted surfaces, tarmac, bulk materials, food, pharmaceuticals and organic materials is measured accurately and easily.
• The sensor is fully configurable for emissivity setting, averaging, peak or valley hold processing, reflected energy compensation, alarm and more, via NFC (Near Field Communications) with the free PyroNFC app for Android.
• Brake testing: The PyroNFC fits in restricted spaces such as between a wheel and a disc brake: It can measure the temperature of the brake disc at the rim or the hub.
• Condition monitoringThe sensor's low cost makes it ideal for measuring many points, and it is possible for the operator to check the temperature at each location with a smartphone with no need for a separate local display
