Wika Models DW & DW10 Stainless Steel Differential Pressure Switch

Stainless Steel Differential Pressure switch for medium/high setting ranges model DW and for for low setting ranges model DW10

By using a diaphragm measuring system, the model DW differential pressure switch is extremely robust and guarantees optimal operating characteristics and the highest measuring performances, with repeatability lower than 1 % of span. 

The process connection with a centre distance of 54 mm lower mount allows an easy and comfortable mounting of a standard valve manifold.
