Pressure Switches Line Guide
Better under pressure. For years, manufacturers and operators of heavy-duty equipment have trusted Honeywell pressure and vacuum switches. They’re proven under pressure, in applications constantly under attack from chemical splashes, performance spikes and other harsh environments. These switches sense a change in the pressure or vacuum, opening or closing an electrical circuit when the designated point is reached.
Honeywell offers an impressive line:
Feature set points ranging from 0.5 psi to 3000 psi. These rugged components have enhanced repeatability of set points and wide media capability. Potential applications include transmissions, hydraulics, brakes, power steering, fuel pressure, oxygen concentrators, dental air, generators/compressors, and pool/spa water pressure.
