Series DA/DS Bourdon Tube Pressure Switch

The Mercoid DA/DS Series is one of the world’s broadest lines of pressure switches.

The DA/DS Series has extremely high sensitivity and great repeatability.

The DA Models are equipped with two external adjustments, one for setting high pressure operating point, the other for setting low pressure operating point.

Deadband, the difference between high and low set points, is adjustable over the full-scale.

The DS Models are equipped with a single external adjustment for setting operating point only.

For mercury-free switches, choose between the snap action switch or hermetically sealed snap action switch.

Hermetically sealed mercury switch also available
