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
