Dwyer Instruments pressure and vacuum switches are used for providing electrical feedback in response to the rise and fall in pressure levels. The brand's DA Series pressure sensors feature a visible calibrated dial that eliminates the need to open the device in dangerous conditions and an adjustable / fixed deadband rated at 0.04 & 0.05 minimum & maximum set points, respectively. These units come with an external switch setpoint for quickly making adjustments and an explosion- & weather-proof housing to facilitate easy accessibility of electrical connections. Choose from a wide range of these switches available in pressure ratings ranging from 5 to 100 psi on Raptor Supplies, an authorised Dwyer Instruments distributor.
