3 in 1 Instrument: Gage, Switch and Transmitter, Square Root Output for Flow
Differential Pressure Controllers are available in 3-in-1 instruments that have a digital display gage, control relay switches, and a transmitter with current output.
 
Features
  • 3-in-1 instrument allows the reduction of several instruments with one product, saving inventory, installation time and money
  • Full scale accuracy of 1.5% even on extremely low ranges, and 0.5% for ranges above 5 in w.c. provide for greater measurement precision
  • Secure menu program provides access to device operation only for the right skill level
Product Applications
  • SCFM flow in ducts
  • Filter status
  • Static pressures in ducts or buildings
  • Damper control
  • Fan control
