Gold Series single-wavelength infrared temperature sensors provide up to 0.25% of reading and measure the amount of infrared energy emitted by an object’s surface, then convert this signal into a temperature value between -40 °F and 4500 °F (-40 °C and 2475 °C). They can be used as stand-alone transmitters with a choice of inputs, outputs and alarms. Interface modules, PID controllers and PC software programs are available.
