These instructions provide information for installation, electrical connection, process con-
nection and calibration of 102 Differential Pressure Switches.
Process pressure is sensed by a piston assembly. The piston responds to differential
pressure and moves a lever connected to a torsionally stiff cross-shaft. One end of the
cross-shaft is connected to a lever that is biased by the range spring. The other end has a
lever that actuates (deactuates) an electrical switching element.
NOTE: If you suspect that a product is defective, contact the factory or the SOR
