Dwyer Instruments 1910-0 Electrical Differential Pressure Switch

The Dwyer Instruments 1910-0 Electrical Differential Pressure Switch is a differential pressure sensing switch that activates when the differential reaches 10 psi, providing a switchable electrical signal at that moment. It is rated for 480 VAC and up to 15 A, enabling direct interfacing with power and control circuits in systems that require immediate response to pressure changes. The unit detects pressure differences across a sensing port and closes or opens an electrical circuit accordingly, making it a straightforward choice for signaling, alarms, or control relays driven by pressure conditions. Key specifications include a 10 psi differential setpoint and a 480 VAC, 15 A electrical rating, with the model designation 1910-0 from Dwyer Instruments. This compact, robust switch is designed to operate in environments where monitoring pressure differentials is essential to maintain system performance and safety.
