1. INTRODUCTION
This user manual provides information on product features and guides you through all basic functions.
1.1. DESCRIPTION
The
FT-1003
Air Volume 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
velocity pressure. The electronic signal is then sent to the square root extractor/multiplier, which
converts the velocity pressure signal into an analog output signal linear to velocity (fpm) or volume
(cfm).
An integral red LED indicator verifies proper power supply wiring orientation.
