Pressure switch GENERAL CHARACTERISTICS ££ The pressure switches PSV4 series use, as sensitive element, a diaphragm or a piston depending on the measuring range. An electrical contact, SPDT type, is activated when the set value is reached. The adjusting screw is mounted on the head of the instruments, you can set the calibration value, within the entire measuring range. Appropriate mechanical stops protect the electrical contact from excess of pressure. The electrical connections is realized via a DIN-43650 plug with IP65 degree of protection. These pressure switches are used in hydraulic and pneumatic equipment, in the industrial plants, pumps, machine tools etc.. • Pressure control from 0.2 to 400 bar. • SPDT contact. • Easy to use and adjust.
