The Gold Series from Williamson Corp. (Concord, Mass.) is a line of single-wavelength, infrared temperature sensors that provide up to 0.25 percent of reading measurement accuracy for noncontact monitoring of product quality and process accuracy. Designed for applications where thermocouples and RTDs would be inaccurate, too slow or difficult to use, these sensors can measure a target’s temperature remotely, making them suitable for use in high-temperature and/or hostile environments and with moving targets (e.g., products passing by on a conveyor). Available in a range of short, long and specialty wavelengths, the sensors measure temperatures between -40°F and 4500°F (-40°C and 2482°C) with reportedly fast response times. To ensure accurate targeting of the substrate, customers may select from line-of-sight, visual, laser-based and fiber-optic light-aiming options. Each model can be used as a standalone transmitter, with a choice of inputs, outputs and alarms. For more advanced capabilities, interface modules, PID controllers and PC software programs are available. 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 measured parameters.
