Discover how electron beam welding, glass-to-metal feed-throughs, and all-welded 316L stainless steel construction give Whitman Controls’ W117 Ultra Pure series a hermetic seal verified at 4×10⁻⁹ Std CC/sec — eliminating off-gassing, internal corrosion, and ingress failure in semiconductor, aerospace, medical, and subsea applications.

Discover how helium leak testing — using mass spectrometry to detect leaks as small as 4×10⁻⁹ Std CC/sec — provides orders-of-magnitude greater hermetic integrity than standard O-ring seals, and why the Whitman Controls W117 Ultra Pure series meets this standard for semiconductor, medical, and aerospace applications.

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.
