PDD Electronic Pressure Switch

Brand: KOBOLD Instruments, Inc.

KOBOLD pressure sensors/switches series PDD are cost effective electronic pressure switches with digital indication of actual pressure. Two switch points, on-/off-switch delay and hysteresis are programmable within the measuring range.

A piezo resistive ceramic sensor is used.

The units can be used where high switching accuracy is needed. Long term stability, repeatability and the compact and robust design make them ideal for use in OEM applications.
