Description
Neodyn 181P NEMA 4X and 13 Adjustable Vacuum Switch represents a high standard in process instrumentation, combining rugged construction with precision engineering. It is specifically built to handle the rigors of industrial settings where accuracy and longevity are paramount.
Stability via Nega-Rate® Technology The defining feature of the 181P series is the utilization of the Nega-Rate® Belleville disc spring. Unlike traditional sensing elements that may drift over time or react poorly to mechanical shock, this disc spring ensures that the set point remains stable. This inherent vibration resistance makes the switch particularly effective in applications involving pumps, compressors, or heavy machinery where movement is constant.
Versatile Adjustment and Control Process control often requires fine-tuning. This switch is equipped with an internal, slotted adjustment wheel, allowing technicians to calibrate the device precisely to the application’s needs. Furthermore, the unit offers a selectable deadband feature, which can be preset at the factory, providing engineers with customizable control over the switching differential.
Robust and Certified Construction Safety and compliance are critical in industrial facility design. The 181P carries electrical listings from Underwriters Laboratories, Inc., CSA International, and FM Approval. The housing is designed to meet NEMA 4X and 13 standards, ensuring protection against corrosion, water ingress, and dust, making it suitable for both indoor and outdoor use in harsh conditions.
