F-4103 Series Spring Biased Comparators

 

U.S. Patent No. 4,315,520
Airtrol Components F-4103 Series spring biased comparators are essentially a regulator with an adjustable bias (positive or negative), and a control or pilot input. Standard units offer a 1:1 ratio, plus or minus the initial bias. Special 3:1 and 5:1 ratio units are also available. Perfect for HVAC applications, and unique control applications requiring a positive or negative offset. Non-rising stem is available with an attractive knob, plain (allowing installation of OEM knobs) or flush for "back panel" installations.
