产品描述

LIMITED STOCK AVAILABLE. This item is being discontinued.
Please see the PSW-150 Series as a possible substitute.

PSW141 Series low differential pressure switches operate on the capacitive principle and are capable of sensing very low positive or negative pressures. In a capacitive cell, a very lightweight, responsive diaphragm deflects slightly when pressure is applied. This deflection results in a change in capacitance which is then detected and processed by solid state circuitry. Reliability and long life are inherent advantages of this design.
