Dwyer Instruments DA-7031-153-4 | Pressure Switch | 1-35 PSIG;SPDT;120-240V AC;brass;bottom mount;1/4" NPT M
Consumers claim that the best pressure switches available are the Series DA/DS Bourdon Tube Pressure Switches. One of the largest ranges of pressure switches available worldwide is the Mercoid DA/DS Series. The sensitivity and repeatability of the DA/DS Series are exceptionally excellent. Two external modifications are available for the DA Models: one for adjusting the operating point at high pressure and the other for adjusting the operating point at low pressure. Over the whole range, the deadband—the difference between the high and low setpoints—can be changed. Only one external adjustment is available for establishing the operating point on the DS Models. We have the snap action switch available for mercury-free switches. There is also a mercury switch that is hermetically sealed.
