Dwyer Series 1620 Single and Dual Pressure Switch
Dwyer, Pressure Instruments, Pressure Switch
Dwyer Series 1620 Single and Dual Pressure Switch
The Dwyer Series 1620 Single and Dual Pressure Switch is the best when the highest precision combined with diaphragm sealed leak-proof construction and mounting simplicity is required. The Dwyer Model 1626 and 1627 differential pressure switches are identical in design and construction, except that Model 1626 has a single electric switch and Model 1627 has dual electric switches.
A Dwyer Model 1627 Dual Pressure Switch can provide dual control when required and can be set to open or close two independent electrical circuits, each preset for its own actuation pressure.
Both Dwyer Series 1620 Pressure Switch models have diaphragm sealed motion take outs providing maximum protection against leakage.
