Neodyn 131P NEMA 4X and 13 Pressure Switch – Adjustable Deadband

Neodyn 131P NEMA 4X and 13 Pressure Switch is a compact, adjustable instrument engineered specifically for pneumatic or low impulse hydraulic process applications. Designed to deliver consistent performance in demanding environments, this switch utilizes the efficient Nega-Rate® Belleville disc spring sensing mechanism, which ensures superior set point stability and exceptional vibration resistance.

Description

Neodyn 131P NEMA 4X and 13 Pressure Switch offers a versatile solution for industrial pressure monitoring, combining rugged protection with flexible control options. Its compact footprint allows for easy integration into tight spaces, making it an ideal choice for skid-mounted systems and complex machinery.

Nega-Rate® Technology Reliability is the cornerstone of the 131P design. It utilizes the proprietary Nega-Rate® Belleville disc spring, a mechanism that eliminates the drift often associated with standard sensing elements. This ensures that the switch maintains its set point accuracy over time, even in environments subject to mechanical shock and vibration inherent in hydraulic and pneumatic systems.

Selectable Deadband Control For advanced process optimization, the 131P series features a selectable deadband. This allows engineers to preset the differential to match specific system dynamics, reducing rapid cycling and extending the lifespan of connected equipment such as pumps and compressors.

Robust and Secure Construction The unit is designed with an internal, slotted adjustment wheel, providing a secure method for calibration that prevents accidental changes during operation. The electrical assembly is a snap-action switch recognized by Underwriters’ Laboratories, Inc. and CSA International, guaranteeing compliance with rigorous industrial safety standards.
