Neodyn 182P NEMA 4 and 13 Vacuum Switch – Tamper Resistant

Neodyn 182P NEMA 4 and 13 Vacuum Switch is a compact and versatile instrument engineered to suit numerous industrial applications. At the heart of this device is the efficient Nega-Rate® Belleville disc spring, a mechanism designed to provide exceptional stability in set points even under challenging conditions.

Description

Reliability and precision are paramount in vacuum monitoring, and the Neodyn 182P delivers on both fronts. This vacuum switch utilizes a snap-action electrical switch recognized by major safety organizations, ensuring it meets rigorous industrial standards. The robust housing is rated for NEMA 4 and 13, making it suitable for environments where protection against dust, water, and coolants is required.

Nega-Rate® Technology The defining feature of the 182P series is the Nega-Rate® Belleville disc spring. This technology eliminates the “trace” or “drift” often associated with traditional sensing elements, ensuring that the switch activates precisely when required.

Tamper-Resistant Architecture Process integrity is maintained through a smart mechanical design. While the unit allows for precise calibration via a 1/8″ allen wrench through the port, the adjustment mechanism is concealed upon installation. This tamper-resistant feature ensures that once your vacuum parameters are set, they remain fixed, reducing the risk of operator error or accidental modification.

Installation Flexibility Weighing approximately 8 ounces, this lightweight unit is easy to integrate into existing piping systems. It features a standard 1/4 NPT Male pressure connection and a 1/2 NPT male conduit connection with pre-wired leads, facilitating quick and secure electrical hookups.
