Dwyer Instruments 1950-00-2F Differential Pressure Switch

The Dwyer Instruments 1950-00-2F Differential Pressure Switch is a device that detects a differential pressure and actuates an electrical circuit when the pressure difference reaches its set point. The model is identified as 1950-00-2F and is rated for operation at 480Vac, enabling it to switch high-voltage circuits. The switch provides a contact-based output suitable for driving relays, controllers, or alarms in automated systems that monitor pressure differentials. By responding to the pressure difference between two points, it enables control actions and signaling in systems where differential pressure is a critical parameter. Because it is a switch, it can be wired to standard control hardware to implement automatic responses without requiring power in the sensing path. The unit is manufactured by Dwyer Instruments, a recognized name in pressure sensing and control products.
