IR-301 controller designed for regulating the Blackbody's Radiating Surface

The New IR-301 controller is a microprocessor based PID (Proportional, Integral and Derivative) system for regulating the Blackbody's Radiating Surface. At Infrared Systems Development, we have taken a leap forward from the standard PID Controller types of past years. We do this by utilizing five (5) independent PID parameter groups, each for a specific temperature range, internally selected based on the Setpoint. To control stability, the Standard Proportional Band with Automatic Reset and Derivative method is utilized. Unlike standard PID control, these parameters are totally dedicated to control stability only. This allows us to reduce the Proportional Band, creating a much more stable Blackbody system.To control warm-up characteristics, we start with an independent Proportional Band, much wider than the stability Proportional Band. We then take the operational span and divide it into five smaller spans. Each of these spans is assigned a factory-selected range of PID Parameters values. Selecting a set temperature automatically loads the proper warm-up parameters into memory for that specific temperature. This process practically eliminates the need for continuous reactionary parameter changes as required by standard PID. For applications requiring one, a Blackbody Radiance Display (WATTS/CM²/STERADIAN) of actual temperature can be monitored at from the front panel LCD display BBRD.
