PDA Pressure Sensor with Ceramic Element

Brand: KOBOLD Instruments, Inc.

KOBOLD pressure transmitter series PDA are cost effective electronic pressure transmitters with digital indication of actual pressure. An analogue output (0)4-20 mA is available for remote transmission of the measured value.

The device is also available with a switch output as well. 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.
