Digital Pressure Transmitter Model PDA

Description

The KOBOLD pressure sensor, model PDA, is a cost
effective electronic pressure transmitter with digital indication
of actual pressure. An analog output of 0(4)-20 mA is available
for remote transmission of the measured value. A switch
output is also available. A piezoresistive sensor is used and
the PDA offers high switching accuracy. Long term stability,
repeatability, and a compact, rugged design makes the PDA
an ideal sensor for use in many OEM applications. Common
applications include: compressor monitoring, installations in
the machinery industry, and pumps.
