Dwyer Instruments Series 3000 Photohelic® Pressure Switch/Gage Model 3015

The Dwyer Instruments Series 3000 Photohelic® Pressure Switch/Gage Model 3015 is a versatile device that combines precise pressure measurement with reliable switching capabilities. Designed for monitoring and controlling differential pressure, it is suitable for various applications, including fan and damper control, environmental pollution control, pneumatic conveying, air conditioning systems, and clean rooms.

Key Features

• Dual Functionality: Integrates a differential pressure gage with low and high set-point controls, allowing for continuous pressure monitoring and control.
• Uninterrupted Gage Reading: The gage reading remains accurate and unaffected by switch operations, ensuring reliable pressure indication even during power loss.
• External Adjustments: Zero and range adjustments are accessible externally, eliminating the need for disassembly during routine service.
• Solid-State Design: Employs solid-state technology for switching, accommodating high cycle rate applications without degradation.
• Easy Installation: Can be flush-mounted in a 4-13/16″ (122 mm) hole or surface-mounted using the provided hardware.
