Temperature measurements in many industrial applications pose significant challenges for thermocouples and resistance temperature devices (RTDs) especially in metal forging, casting, milling, finishing and heat treating as well as boilers, incinerators, kilns and glass forming. In these and other applications, infrared (IR) temperature sensors can overcome accuracy, response time and implementation issues. Williamson Corporation’s Pro 100 and Pro 200 Series are multi-wavelength IR temperature sensors that routinely address these issues. The company’s multi-wavelength sensors utilize custom algorithms to provide aim-and-read capabilities for non-greybody materials that are not accurately measured by single and dual-wavelength sensors.
By measuring the amount of infrared energy emitted by an object’s surface and converting the signal into a temperature value, the sensors can read temperatures between 95° and 2500°C (200° and 4500°F). Accuracy is within 2°C or 0.25% of the reading (whichever is greater). Pro 200 Class sensors use a small, Teflon-sealed fiber-optic cable that can withstand ambient temperatures as high as 200°C (400°F) or higher with optional accessories to view the target while the sensor is mounted in a remote or more convenient location.
