Infrared Temperature Sensors

Williamson Corporation’s Gold Series single-wavelength infrared temperature sensors provide up to 1/4% 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. 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 the sensors include the processing of plastics.

When in the stand-alone mode, the local interface of the 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.

Williamson offers a choice of wide-angle or high-resolution optics. Sensor alignment options are line of sight, laser aiming, and a fiber-optic aim light. To simplify the installation of a Gold Series sensor and provide additional protection for severe environments, the company offers a wide selection of accessories, including mounting brackets, flanges, water-cooling hardware, and rugged hazardous-area enclosures.
