No floats, no buoyancy, no moving parts — vibrating fork level switches use resonance frequency shifts to detect liquids, powders, and granules with maintenance-free reliability. Here’s how Whitman Controls’ L90, L91, and L92 series handle everything from aggressive chemical liquids to bulk solids across temperatures up to 482°F and pressures to 218 PSI.

Diaphragm, piston, or capsule; the sensing element inside your pressure switch determines everything from surge tolerance to contamination risk. Here’s how to match Whitman Controls’ P117, J705, and W117 series to your system pressure, media compatibility, and set point requirements before the wrong choice becomes a field failure.

Too little deadband and your switch chatters itself to failure. Too much and your process drifts beyond safe limits. Here’s what engineers need to know about differential, hysteresis, and how Whitman Controls’ P88G, J205G, and P605 series are matched to the right balance for pumps, hydraulic rigs, and high-spike industrial environments.
