This product is a special order item which can’t be returned or cancelled.
Tested being installed in thousands of pipelines and processing plants around the world. A magnetically actuated switching design gives superior performance. There are no bellows, springs, or seals to fail. Instead, a free-swinging vane attracts a magnet within the solid metal switch body, actuating a snap switch by means of a simple lever arm.
Used to monitor unattended equipment and protect it from costly damage. Utilizes a rugged, hermetically sealed reed switch which is encapsulated in a polypropylene switch housing that fits into a standard heavy duty leak proof brass body or optional 303 Stainless Steel body.
Flowing medium presses against the paddle of the flow switch. The paddle is fitted to one end of a balance arm which is in direct contact with a pre-stressed leaf spring; at the other end of the balance arm is a permanent magnet. The magnet actuates a reed contact located within a moveable plastic housing.
