Field of View Diagrams

Please 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 Calex sensors detect only the wavelengths of infrared radiation that are not absorbed by the atmosphere.

Minimum Measurable Temperature (PUA2-151-LT only)

Graph showing the minimum measurable object temperature (Tmin), determined by surface emissivity (ε) and sensor temperature (Ts). Applies to model PUA2-151-LT only.

Electromagnetic Compatibility Standards

Conforms to EN61326-1, EN61326-2-3 (Electrical Equipment for Measurement, Control and Laboratory Use – EMC Requirements – Industrial)

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

Aplicaciones Típicas

Acero

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.

Air Purge Collar

The air purge collar is used to keep dust, fumes, moisture and other contaminants away from the lens. Air flows into the fitting on the side and out of the aperture at the front.

Fixed Mounting Bracket

The L-shaped fixed mounting bracket offers a rigid support for the sensor and allows fine rotational adjustment about one axis.

Adjustable Mounting Bracket

The adjustable mounting bracket consists of a fixed mounting bracket plus another L-shaped bracket. When assembled as shown, the adjustable mounting bracket offers a rigid support for the sensor and allows fine two-axis adjustment.

Air/Water Cooled Housing

The air/water cooled housing allows the sensor to withstand ambient temperatures above the normal limit. Depending on the degree of cooling required, air or water may be used as the cooling fluid. To prevent condensation forming on the lens, an air purge collar is included with this item. The air/water cooled housing must be ordered with the sensor and cannot be fitted by the user.

Laser Sighting Tool

The Laser Sighting Tool screws onto the front of the sensor during installation and shows precisely where the sensor is aiming. Once the sensor has been aimed at the centre of the target and locked in position, the Laser Sighting Tool can be removed. The laser is operated via a latching push button on the front of the tool.

Dual Laser Sighting Bracket

The Dual Laser Sighting Bracket is a sturdy mount for the sensor and provides continuous target sighting while measurements are being taken. Two parallel lasers indicate the centre of the measured spot and are controlled by a remote switch on the electronics module.

PID Controllers and Indicators

The 4-20 mA output of the PyroUSB may be connected to any of our indicating controllers, which provide temperature display, PID control and alarm relay outputs.
