Neodyn 122P NEMA 4X, 7, 9 and 13 Pressure Switch – Internal Adjustment

Neodyn 122P NEMA 4X, 7, 9 and 13 Pressure Switch is a compact, adjustable instrument engineered specifically for low to mid-range process applications. Designed to withstand harsh industrial environments, this switch combines a robust 316 stainless steel body with a wide selection of wetted materials, making it an ideal choice for demanding chemical process applications. Its internal adjustment mechanism allows for secure set point configuration while maintaining the integrity of the explosion-proof enclosure.

Description

Neodyn 122P Series sets the standard for reliability in hazardous locations. At the heart of this device is the efficient Nega-Rate® Belleville disc spring, a technology that provides exceptional set point stability and vibration resistance. This snap-action mechanism ensures that the Neodyn 122P NEMA 4X, 7, 9 and 13 Pressure Switch delivers accurate repeatability, eliminating the drift often associated with conventional tracing elements.

Optimized for Chemical Compatibility

Engineers often face challenges when selecting switches for aggressive media. The 122P addresses this with a wide selection of wetted materials and a durable 316 stainless steel exterior and interior. Coupled with hermetically sealed, explosion-proof electrical assemblies, this switch offers complete atmospheric protection. The internal, slotted adjustment nut with a range scale facilitates precise field calibration without exposing the internal components to the environment, ensuring safety and longevity in volatile zones.
