Air Operated Sensor and Switch
What is an Air Part Sensing Device?
Low-Cost, Medium Speed, Non-Contact Detection. The Jet-Tron Detector (Model 8900) is a low-cost, air-operated control unit that detects any solid object without physically contacting it. It can detect any material which is capable of interrupting a small low-pressure stream of air. Any solid object which interrupts the air stream will cause a change in air pressure on the diaphragm. This, in turn, changes the state of the contacts of an internal micro switch.
8902 Jet-Tron
Entire kit, part number 8900, featuring flow
control valve, sensor, fittings and air lines.
The reaction time of the air operated Jet-Tron Detector is slower than electronic detection devices; however, it is more than adequate for such applications as parts feeding, broken tool detection, on/off control of conveyors and auxiliary processing equipment, and most limit switching.
The Jet-Tron is ideal for detecting glass and other transparent or translucent materials which are not efficiently sensed by some types of electronic detectors.
