The Dwyer Instruments 3000-0C Photohelic Pressure Switch is a pressure-triggered switch that actuates an electrical output when the sensed pressure reaches its preset setpoint. Designed for use in systems that require reliable pressure monitoring and automatic control, it provides a switch signal suitable for relays, alarms, or interlocks in industrial or process environments. With the model number 3000-0C, this device belongs to Dwyer’s Photohelic line and is intended for integration into pneumatic or fluid pressure control schemes where a defined pressure threshold is used to initiate a control action.
