1540 Side Mounted Pneumatic Level Switch

1540 is a horizontally mounted, floatoperated level switch suitable for plant and OEM applications where pneumatic valve operation is required to signal presence or absence of liquid at a discrete level. The float arm moves a magnet which in turn moves a shuttle that either blocks or allows pilot pressure to pass and operate ancillary equipment. Actuation (deactuation) can be reversed by rotating the unit 180 degrees or switching inlet connections. The supply media must be filtered and oil free. Air is the usual media; however, any dry, filtered gas can be used.
