Williamson's Pro multi-wavelength infrared temperature sensors provide predictive maintenance in challenging conditions

Williamson’s Pro 100 and Pro 200 Series multi-wavelength infrared temperature sensors use ESP algorithms to provide “aim-and-read” capabilities for non-greybody 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. The sensors measure the amount of infrared energy emitted by an object’s surface, then convert this signal into a temperature value between 200 and 4500 °F (between 95 and 2500 °C). Accuracy is within 2 °C or 0.25% of the reading (whichever is greater).

Pro 100 sensors utilize visual or integrated-laser aiming alignment. Pro 200 sensors utilize fiber-optic alignment, with an integrated aim light available as an option.

Every Pro 100 and Pro 200 sensor can be used as a stand-alone transmitter with a choice of inputs, outputs, and alarms. For more advanced capabilities, remote interface modules, PID controllers, and PC software programs are available. When in the stand-alone mode, the sensor’s local interface is used to display the temperature and adjust sensor settings from an intuitive text-based menu. Units are compatible with bidirectional RS232 and RS485 communications as well as 4-20mA and voltage-sensor outputs, which may be programmed with a choice of up to five different measured parameters.
