8820-21 & 8822-23 Infrared Probes

The LED Source Probe emits an invisible beam of light in the infrared spectrum. These emissions are sent out of a series of pulses at a fixed rate of speed. The phototransistor receiver probe (or element) detects these emissions. The receiving circuit is synchronous with the pulse rate of the source probe. This feature significantly reduces false signals from external light sources.

8820 LED (light emitting diode) probe and 8821 receiver (phototransistor) replacement probes for formerly used 8800 Sensitron back pressure controller.
