OUTLINE
1
The ProcessX V5 series transmitter accurately measures the differential pressure, level of liquid,
gauge pressure or absolute pressure, and transmits a proportional current signal of 4 to 20 mA DC.
This transmitter can be used for flowrate, level, density measurement and other application using
differential pressure measurement.
The transmitter utilizes a unique micromachined capacitive silicon sensor with state-of-the-art
microprocessor technology to provide exceptional performances and functionnalities.
The transmitter is compact and light, provide high accuracy and reliability.
Transmitter settings (such as range and damping time constant, etc.) can be changed from an
HHC (Hand Held Communicator) or with an optional LCD digital display.
Local digital adjustment of zero and span are possible from outside screw on the electronic housing.
Measuring principle
The operating principle of the ProcessX V5 series transmitter is shown in the below block diagram.
The input pressure is changed into an electrostatic capacitance in the detecting unit.
The change proportional to the pressure undergoes conditioning and amplification in the trans-
mission unit, and is then output as a current of 4 to 20 mA DC
