Description
Neodyn 180P NEMA 4 and 13 Vacuum Pressure Switch stands out as a heavy-duty solution for vacuum monitoring. Unlike lighter compact switches, this unit is constructed for durability and ease of field serviceability, featuring a concealed adjustment mechanism that protects settings from accidental changes while remaining accessible for authorized personnel.
Nega-Rate® Technology for Stability The 180P utilizes the proprietary Nega-Rate® Belleville disc spring system. This snap-action mechanism eliminates the drift and instability often found in standard diaphragm or piston switches. It ensures that the switch actuates precisely at the defined set point, providing reliable feedback to control systems and alarms.
Weatherproof and Robust Construction Engineered for versatility, the enclosure meets NEMA 4 and 13 standards, providing protection against windblown dust, rain, splashing water, and hose-directed water. This makes the 180P suitable for installation in washdown areas or outdoor plants without the need for additional protective housing.
User-Friendly Adjustment Calibrating the 180P is straightforward thanks to its concealed wrench flat adjustment design, which includes a visible range scale. This allows technicians to set the vacuum threshold accurately without guessing. Additionally, the electrical connection is facilitated by a 1/2 NPT female conduit connection leading to an internal terminal block, simplifying wiring and maintenance compared to pre-wired lead models.
