Wika Model DW03UN Low Range Differential Pressure Switch

By using a diaphragm measuring system, the model DW03UN 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.
