Dwyer 1950 Differential Pressure Switch is an explosion proof* pressure switch for air and compatible, non-combustible gasses. The Dwyer 1950 is often considered an upgrade to the low cost Dwyer 1900 Series Differential Pressure Switch as it has a more rugged and IP54 style housing.
*IMPORTANT. Note that, although explosion proof for some international markets, the Dwyer 1950 is not compliant to ATEX standards for use in European hazardous areas. The 1950 has a simple, power free (dry contact) switch. If you require an ATEX compliant unit, consider the Dwyer 1950G ATEX Differential Pressure Switch (requires 24V supply) or the Exia and Exd compliant Pyropress PERSEUS Pressure Switch with volt free/dry contact that Fluidic offer.
Fluidic can supply the Dwyer 1950 switch pre-set, against a calibrated reference, to suit user requirements.
