1. INTRODUCTION
This user manual provides information on product features and guides you through all basic functions.
1.1. DESCRIPTION
The
FIT-1003M
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). The measured process air velocity/volume is independently indicated on a front panel mounted
magnehelic pressure gauge scaled in both cfm and fpm. This independent readout allows for quick and
immediate indication of Flow and Velocity and verification that the electronic transducer is operating
effectively. An integral red LED indicator verifies proper power supply wiring orientation.
