The customer told us that the DA/DS series Bourdon tube pressure switch is the best pressure switch. The Mercoid DA/DS series is one of the most extensive pressure switch series in the world. The DA/DS series has extremely high sensitivity and good repeatability. The DA type is equipped with two external adjustment devices, one for setting the high voltage operating point and one for setting the low voltage operating point. The dead zone, the difference between the high and low setting values, is an adjustable full-size. The DS model is equipped with a separate external adjustment setting operating point. For mercury free switches, choose quick action switches or sealed quick action switches. Sealed mercury switches can also be provided.

●  On/off indication (except hermetically sealed snap switch models) gives operator clear indication of state of switched equipment that could be located in another location

●  Adjustable or fixed deadband supports control applications by reducing equipment wear-out by unnecessary recycling

●  External switch setpoint adjustments reduces set-up time

●  Pressure ranges of full vacuum to 8000 psig gives application designers the ability to specify standard equipment, simplifying install and training, and reducing servicing costs

●  UL listed, CSA approved many models FM approved to support rigorous process applications and regulations

●  General purpose, weatherproof or explosion-proof enclosures for a variety of indoor or outdoor environments meeting the needs of multiple applications and uses
