The Dwyer Instruments 43300-30CM Capsu-Photohelic® Switch/Gage is a versatile and highly repeatable pressure switch combined with a precise analog pressure gauge. Utilizing the time-proven Magnehelic® gage design, this instrument provides accurate pressure measurement and control in demanding industrial applications. With an encapsulated sensing element, it is suitable for use with both liquids and gases at pressures up to 300 psi (20.7 bar). The optional cast brass case ensures durability and compatibility with water or water-based liquids.
Key Features & Highlights
- Dual Functionality: Combines a precise pressure gauge with two phototransistor-actuated DPDT relays for low/high limit control.
- Wide Pressure Range: Measures and controls pressures from 0 to 300 psi (0 to 20.7 bar) with a 1/4 NPT connection.
- Encapsulated Sensing Element: Designed for use with both liquids and gases, offering versatility across various media.
- Easy Adjustable Set Points: Knobs on the gauge face allow for simple adjustment of set point indicators.
- Narrow Deadband: Individual set point deadband is less than 1% of full scale, ensuring precise control.
- Interlock Capability: Set points can be interlocked to provide variable deadband, ideal for pump control and other applications.
- Rugged Construction: Optional cast brass case provides durability and resistance to harsh environments.
Applications
The Dwyer Instruments 43300-30CM is ideal for industrial processes requiring reliable pressure monitoring and control. Common applications include pump control, HVAC systems, hydraulic and pneumatic systems, and general industrial pressure measurement where both indication and switching are needed.
