Keller PD39X Series Differential Pressure Transmitter

Keller PD39X Series Differential Pressure Transmitter

Quick Overview

The Keller PD39X series differential pressure transducer is designed to indirectly measure differential pressure by using two absolute pressure sensors providing a more robust sensor in relation to unbalanced pressures that transducers using a single sensor. Differential pressure ranges between 0-3 and 0-300 bar are available with output signal options of 4-20mA and 0-10V. These units also have an RS485 output in addition to the standard analogue outputs. Typical error band ≤0,05 %FS typ. (linearity, hysteresis, repeatability and temperature effect

Piezoresistive Differential Pressure Transmitters based on two Absolute Sensors

In applications where the differential pressure is more than 5% of the maximum standard pressure range, differential pressure measurement with two absolute pressure sensors offers major advantages over conventional methods of differential pressure measurement (such as the Series PD-10).

The Series PD-39 X does not measure the differential pressure directly - instead, it uses two absolute pressure sensors to take the measurement indirectly. As well as reducing costs, this differential pressure transmitter is also more robust in relation to unbalanced (one-sided) overloading. The differential pressure range should be at least 5% of the standard pressure range. Each pressure side has two pressure connections, so the PD-39 X is easy to use in pressure lines.

Each Series 30 transmitter also integrates a digital interface (RS485 half duplex) which you can make use of: Connect the transmitter to a PC or Laptop via the converter K106 (RS232-RS485). Two programs are offered: READ 30 and PROG30.
