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

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.

The backlit touch screen interface mounted in the lid of the electronics module provides a large, bright display of the measured temperature, as well as controls allowing full configuration of the sensor. The graph view shows the history of the measured temperature. In alarm conditions, the display turns bright red to provide an immediate and obvious alarm indication. Alarm modes and levels can be configured via the touch screen. The FibreMini can be used as a standalone data logger. All models include a MicroSD card slot for data logging, which can be configured via the touch screen interface. The user can select the sample rate and the number of samples to be taken and schedule the data logging to start at a certain time. With a MicroSD card larger than 2 GB, years of data can be stored, even at the fastest possible sample rate of 1 per second. Data is stored in .csv format and can be viewed and edited easily using spreadsheet software. Alarm events can also be logged to the MicroSD Card. A MicroSD card with SD card adapter is available as an optional accessory. The MicroSD card slot and battery holder are located inside the electronics module. Readings are time and date stamped using the sensor’s internal clock. The clock is reset when the power is disconnected, or it will continue if the optional battery is fitted.

The PyroCAN series is a range of general purpose infrared temperature sensors (pyrometers) that measure the temperature of surfaces without contact. The temperature is transmitted digitally every 200 ms via a CAN interface. The sensor’s CAN ID and emissivity setting may be changed via a CAN command. The sensor is suitable for measuring a variety of non-metal surfaces, including painted materials, rubber, plastics, asphalt, soil, plants, organic materials, food and pharmaceuticals. Metals can be measured if they are painted or heavily oxidised. The PyroCAN is easily connected to existing networks with other CAN devices.

The ExTemp is an intrinsically safe pyrometer. It measures the temperature of surfaces in hazardous areas without contact, and provides a direct 4-20 mA output. It is certified to ATEX, IECEx and TIIS standards.Explosion proof pyrometers typically have bulky, expensive housings, however because the ExTemp uses Intrinsic Safety as the method of protection, it is compact and low-cost.
Note: The given measured spot size contains 90% of the energy detected by the sensor. We normally recommend the target is at least twice as large as the given measured spot for maximum accuracy. Sensors may be used at longer distances than the above diagrams show. There is no maximum measurement distance in clean air; this is because the ExTemp detects only the wavelengths of infrared radiation that are not absorbed by the atmosphere.
Petrochemical - condition monitoring
Bearing, gearbox and motor housing surface temperatures in refineries and chemical plants can be monitored without contact, eliminating the need to replace contact probes that are easily damaged by vibration.
Petrochemical - liquid storage and processing: The sensor can be positioned in a Zone 0 environment such as the top of a tank of hazardous liquid or reactor, to measure the surface temperature of the liquid.
Paper: Dust in pulp, paper and packaging plants can create a fire and explosion hazard. The ExTemp intrinsically safe pyrometer can be used for paper web temperature measurement and condition monitoring in ATEX and IECEx classified hazardous areas.
Coal conveyors: The ExTemp's fast 240 ms response time makes it ideal for measuring the surface temperature of coal on conveyors, as well as other bulk materials where there is an explosive dust hazard.
Gas cylinder filling: The surface temperature of cylinders of explosive gases is monitored with the ExTemp as they are filled. The Group IIC, T4 classification makes it suitable for almost all gases including propane, butane, hydrogen and acetylene. The temperature of each cylinder is measured on the filling rig to help detect fault conditions in filling, to calculate the final filled volume (in conjunction with the pressure), to ensure the volume is repeatable, and to improve the filling rate.
Automotive painting: Solvents in automotive painting can create a gas explosion risk. The intrinsically safe ExTemp may be used to monitor the temperature of containers and vessels, the surface temperature of liquids and powders, and the temperature of painted surfaces.
Offshore: The ExTemp's 316 stainless steel housing and intrinsically safe certification makes it well-suited for use on offshore platforms. As well as measuring the temperature of surfaces on the rig, it can be used to measure the temperature of the sea surface.
