Infrared Temperature Sensors Are Highly Accurate
Williamson Corporation’s Gold Series single-wavelength infrared temperature sensors provide up to ¼% of reading measurement accuracy for monitoring and controlling product quality and process productivity. Configurable for a multitude of applications where devices such as thermocouples and RTDs would be inaccurate, too slow, or difficult to use, they measure a target’s temperature without contact, making them ideal for high-temperature environments, moving targets, and fast response times.
Available in a complete range of precisely selected short, long, and specialty wavelengths, Gold Series infrared sensors measure the amount of infrared energy emitted by an object’s surface, then convert this signal into a temperature value between -40° and 4500° F (between -40° and 2475° C). Each model can be used as a stand-alone transmitter with a choice of inputs, outputs, and alarms. For more advanced capabilities, interface modules, PID controllers, and PC software programs are available.
Sample applications for Gold Series sensors include metal forging and milling; metallic mold and dies; heat treating; boilers; thermal reactors; incinerators; kilns; flares; and the processing of paper, rubber, textiles, plastics, ceramics, and glass.
When in the stand-alone mode, the local interface of a Gold Series sensor is used to display the temperature and adjust sensor settings from an intuitive text-based menu. An optional analog input is available for remote emissivity and alarm adjustments. 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. An addressable networking option for most of the industry’s bus protocols will be released in the spring of 2010.
