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.

• Simple – Save installation time and reduce the cost of instrumentation on the machines you build with the PyroMini OEM.
• Easy – This simple sensor works straight out of the box with no configuration necessary.
• Accurate – Fixed emissivity setting provides accurate measurements on non-reflective materials such as paper, foodstuffs, organic materials, rubber, painted surfaces (including painted metals) and thick plastics.
• Compact – Install the sensor where space is limited. The sensing head measures just 55 mm long, with a right-angled cable entry.
• Industry standard outputs – A choice of robust industrial analogue outputs including 4-20 mA, thermocouple or voltage allows the sensor to be connected directly to an existing temperature indicator or controller.

• 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)
