Model 2PSVac
Solon Model 2PS Vacuum Switch
The 2PS employs Solon's unique, rugged, and sensitive switching mechanism. Unlike most "inline" vacuum switch designs, the Solon mechanism is frictionless and amplifies the movement of the sensing element. This results in improved life, repeatability, and lower deadbands. The 2PS mechanism can be supplied with one S.P.D.T. electric switch or two S.P.D.T. electric switches that are independently adjustable. The unit can be supplied with no housing,
or enclosed in a rugged die cast NEMA 4X, 12 and 13 housing. With the cover of the enclosure removed, the terminals of the electric switch(es), and the adjustment(s) are exposed for easy wiring and adjustment of the vacuum setting. The die cast cover is equipped with captive stainless steel screws that retain the cover gasket when the cover is removed. Other useful options can easily be specified with this model. See the Special Features section on page 2 for special
wetted materials and options for particular applications.
OTHER 2PS MODELS ARE AVAILABLE
The modular design of pressure-sensing elements used in the 2PS series switches allows a variety of models for different pressure applications. These applications include High Pressure, Differential Pressure, Vacuum, and Vacuum-Pressure models using diaphragms, bellows, and pistons for actuation.
