Section 2 - Introduction

The FMA1000 series industrial air velocity/temperature transmitter/indicator
measures and displays air velocity mass flow and air temperature of clean air
flows in ducts & pipes, while producing very little pressure drop in the flow
stream. The FMA1000 series can be used in research & development labs,
HVAC applications, and other manufacturing processes. The sensor design is
based on three RTD elements, one measures the air temperature and the other
two measure the air velocity. The air velocity is measured based on the heat
loss from the RTD velocity sensor as it cools down by the air flow.
The FMA1000 series offers many standard features such as dual display of
air velocity & temperature, two analog outputs corresponding to air velocity
& temperature, high & low voltage alarm outputs for air velocity, USB PC
interface with a Windows based PC interface software. The FMA1000 displays
the air velocity in feet per minute (FPM), meter per second (m/s), miles per
hour (MPH), and kilometer per hour (Km/h). The air temperature is displayed
in ºF & ºC.
The sensor probe is 12" long as standard. The 304 Stainless steel sensor tubing
is provided with inch marks for ease of insertion depths. The sensor probe
comes in four different versions as follows:
• Fixed probe mount
• Right angle probe mount
• Remote probe
• Fixed short probe, 3.75" Long
