Dwyer Series 1620 Single and Dual Pressure Switch 1626-1

Dwyer Series 1620 Single and Dual Pressure Switch 1626-1,
On the Series 1620 Single and Dual Pressure Switch our old faithful switch design
is still best where highest precision combined with diaphragm sealed leak proof
construction and mounting simplicity are required. 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. Model 1627
can therefore provide dual control when required. It can set to open or close two
independent electrical circuits, each preset for its own actuation pressure. Both units
have diaphragm sealed motion take outs providing maximum protection against
leakage.
