1. INTRODUCTION
The DFT Series, Differential Pressure Transmitter - Fixed Range can accurately
measure negative, positive, combination of both (compound), or differential pressure mainly
applied to air and neutral gases. The DFT Series is not position sensitive and can be
mounted in any orientation without compromising accuracy. The DFT series has a
lightweight, compact and simplified design makes it suitable for industrial applications.

 Air and Neutral Gases
 HVAC Applications
 Clean Room Applications
 Filter Status
 Duct Static Pressure
 Fan and Blower Pressure
 Paint Shops
 Dust Collectors
 Bubbler Systems
 Cabinet Purging
