Dwyer Instruments Series 3000 Photohelic Pressure Switch Gage Model 3006

Dwyer Instruments Series 3000 Photohelic® Pressure Switch/Gage Model 3006

The Dwyer Instruments Series 3000 Photohelic® Pressure Switch/Gage Model 3006 is a versatile instrument that combines precise pressure measurement with reliable switching capabilities. Designed for monitoring and controlling positive, negative, or differential pressures of air and compatible gases, this device is ideal for applications such as fan and damper control, environmental pollution control, pneumatic conveying, air conditioning systems, and clean rooms.

Key Features

• Dual Functionality: Integrates a highly accurate pressure gage with two adjustable pressure switches, allowing for continuous monitoring and control within a single unit.
• Accurate Measurement: Provides pressure readings with an accuracy of ±2% of full scale at 70°F (21.1°C), ensuring reliable performance in critical applications.
• Adjustable Setpoints: Features easy-to-use knobs on the gage face for setting high and low pressure limits, facilitating quick adjustments without the need for disassembly.
• Independent Gage Operation: The gage continues to display accurate pressure readings even if power to the electrical components is interrupted, ensuring continuous monitoring.
• Robust Construction: Built to withstand pressures from -20″ Hg to 25 psig (-0.677 to 1.72 bar), with optional configurations available for higher pressure limits.
