Discover how the Whitman Controls W117 Series — with all-welded 316L stainless steel construction, electron beam welding, and helium leak testing to 4×10⁻⁹ Std CC/sec — delivers zero-contamination pressure and vacuum monitoring for semiconductor ALD equipment, medical radiography, and aerospace electron beam welding chambers.

Discover how Whitman Controls’ L95 hydrostatic and L96 capacitance level transmitters deliver real-time chemical inventory data — enabling predictive replenishment, early leak detection, and precision process control in aggressive, pressurized, and ultra-pure chemical storage environments.

Not all industrial enclosures offer the same protection. NEMA 4, 4X, and 6 ratings each serve a distinct purpose — from handling heavy washdowns to resisting corrosive chemicals and surviving full submersion. Understanding the difference ensures your sensors and switches are built to last in the environments they actually operate in.

Hysteresis in industrial pressure switches defines the lag between a switch’s actuation set point and its reset point also known as the deadband or differential. Understanding and correctly specifying this differential is critical for preventing system chatter, extending motor life, and ensuring reliable performance in demanding applications. Learn how Whitman Controls engineers predictable, repeatable hysteresis into every pressure and vacuum switch, from field-adjustable models like the P117 and J205 series to severe-duty piston-actuated switches that withstand spikes up to 9,000 PSIG.

Discover how Whitman Controls’ L95 hydrostatic and L96 capacitance level transmitters deliver real-time chemical inventory data — enabling predictive replenishment, early leak detection, and precision process control in aggressive, pressurized, and ultra-pure chemical storage environments.

Discover how Whitman Controls’ L30 series multi-level switches consolidate up to six discrete level points onto a single center shaft — replacing multiple individual sensors, reducing spare parts inventory by up to 16%, and delivering layered low-level warnings, emergency cut-outs, and overflow protection through one tank connection.

Discover how to choose between vertical and side-mount liquid level switches — comparing the Whitman Controls L20, L30, L60, and L54/L55 series across tank geometry, pressure ratings, material compatibility, and multi-point control requirements to find the right orientation for your specific industrial application.

Nuisance trips in industrial automation cost more than downtime — they cause alarm fatigue, mechanical wear, and safety blind spots. This guide covers five proven engineering strategies to reduce false actuations: from tuning hysteresis and adding signal delays to choosing the right sensor technology and transitioning to predictive monitoring.

In industrial tank management, a hydrostatic pressure sensor is one of the most reliable tools for determining liquid volume. Unlike ultrasonic or radar sensors that measure from the top down, a hydrostatic sensor like the Whitman L95 Series measures the weight of the liquid column above it. This guide covers how to convert raw pressure readings into accurate volume data — from calculating liquid height and accounting for specific gravity, to applying the right tank geometry formula and scaling signals in PLCs and panel meters.

The industrial world is moving from reactive maintenance to predictive intelligence.
