Learn how to calibrate temperature probe switches for industrial ovens step by step — from setting up a dry block calibrator to identifying actuation points and making field adjustments. Whitman Controls explains best practices for high-temperature environments.
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.
