Honeywell Thermal Solutions FSG L404F1375 Pressure and Limit Controller

Pressure and Limit Controller from Honeywell Thermal Solutions, model FSG L404F1375, provides reliable safety and precise control for steam, air, and non-corrosive fluids. This Pressure and Limit Controller uses an adjustable subtractive differential and a diaphragm-operated mechanism to maintain accurate limits within a 5 to 50 PSI operating range and a 6 to 14 PSI differential.

With SPDT two-circuit contacts and rugged 1/4" female threaded connections, it is UL and CSA approved for industrial use. The unit covers a wide operating temperature from -35 to 150°F and features auto-recycle snap-action switching that makes R-W on pressure rise, delivering consistent cycle control in demanding environments.
