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 switch control. 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 phototransistor-actuated DPDT relays for low and high limit control.
• Continuous Pressure Indication: Provides uninterrupted pressure readings, even during power loss, ensuring consistent monitoring.
• Easy Set Point Adjustment: Features user-friendly knobs on the gage face for straightforward set point configuration.
• Minimal Deadband: Offers a deadband of less than 1% of full scale, ensuring precise control and reducing the risk of system oscillation.
• Flexible Mounting Options: Can be flush-mounted in a 4-13/16″ (122 mm) hole or surface-mounted using the provided hardware.
