WILLIAMSON Pro 100 and Pro 200 Series multi-wavelength infrared temperature sensors are suitable for a multitude of industrial applications where devices such as thermocouples and RTDs would be inaccurate, too slow, or difficult to use. Devices use ESP algorithms to provide ‘aim-and-read’ capabilities for non-grey body materials (annealed, galvannealed and stainless steel; aluminum; brass; copper; zinc; etc.) that are not accurately measured by single- or dual-wavelength sensors because their change in emissivity varies by wavelength. Products measure the amount of infrared energy emitted by an object’s surface, then convert this signal into a temperature value between 95C and 2500C. Accuracy is within 2C or 0.25% of the reading (whichever is greater).
