GENERAL DESCRIPTION
The pressure switch, model PDD, is a cost effective, electronic pressure switch with digital indication of actual pressure. One or two switch points, on/off-switch delay, and hysteresis are within the programing parameters. A piezoresistive ceramic sensor is used for high cycle life and the sensors can be used where high switching accuracy is needed. Long term stability, repeatability, and a compact robust design makes the PDD an ideal sensor for use in many OEM applications. Common applications include: compressor monitoring, installations, the machinery industry, and pumps.
