1. INTRODUCTION
This user manual provides information on product features and guides you through all the basic
functions of the DPT-4001.
1.1. DESCRIPTION
The
DPT-4001
differential pressure transducer sensor operates on the capacitance principal and is
capable of sensing ultra low differential pressures. In the capacitance cell, a very lightweight,
responsive diaphragm deflects a small amount when pressure is applied. This deflection results in a
change in capacitance, which is then detected and processed electronically into an output signal linear to
the differential pressure.
The DPT-4001 can be configured as a Unipolar device (positive differential
pressure only) or a Bipolar device (positive and negative differential pressures). A power indicator
illuminates when power is attached correctly.
