Dwyer Series 43000-0 Capsu-Photohelic Pressure Switch Gage 0-.5" w.c.

Model	Description
43000-0	Pressure Switch/Gage, Range 0-.5" w.c.

Lo-Limit and Hi-Limit Control, Aluminum Case

Capsu-Photohelic Switch/Gages function as versatile, highly repeatable pressure switches combined with a precise pressure gage employing the time-proven Magnehelic gage design. The Capsu-Photohelic switch/gage employs an encapsulated sensing element for use with both liquids and gases at pressures to 500 psig. Two phototransistor actuated, DPDT relays are included for low/high limit control. Easy to adjust set point indicators are controlled by knobs located on the gage face. Individual set point deadband is one pointer width - less than 1% of full scale. Set points can be interlocked to provide variable deadband - ideal for control of pumps, etc.

Dual Set Point Switching for Enhanced Control

The Series 43000-0 features highly reliable DPDT snap switches for dual set points, optimizing both alerting and control in industrial applications. Its instantaneous mechanical response allows for quick switching, making it indispensable in safety-critical systems. The analog display delivers precise, easy-to-read outputs, ensuring operators can monitor pressure changes effectively.

Rugged and Versatile Industrial Design

Constructed from die-cast aluminum and finished with black baked enamel, this gage resists harsh conditions. The panel-mount design and IP54 front protection allow for surface or flush installation in various industrial settings. Accessories include mounting brackets and wiring instructions, simplifying the setup wherever pressure monitoring is required.

Effortless OperationNo Power Supply Needed

Operating solely via mechanical action, the Capsu-Photohelic gage does not require an external power supply. With an accuracy of 2% of full scale and a sealed neoprene construction, users benefit from reliable measurement of air and compatible gases, minimizing maintenance and power concerns.

FAQs of Dwyer Series 43000-0 Capsu-Photohelic Pressure Switch Gage 0-.5" w.c.:

Q: How does the Dwyer Series 43000-0 Pressure Switch Gage operate without an external power supply?

A: This pressure switch gage uses a fully mechanical, electromechanical design, relying on inherent pressure changes to actuate its DPDT snap switches and analog indication. Therefore, no external electrical power source is required for normal operation.

Q: What is the recommended process for installing the Series 43000-0 gage?

A: For best performance, panel mounting is preferred but surface mounting is also supported. Use the supplied mounting brackets and wiring instructions, and connect the 1/8" female NPT pressure ports to your compatible air or gas lines. Ensure the enclosures IP54-rated front is not exposed directly to liquids.

Q: When should I use this Capsu-Photohelic Pressure Switch Gage?

A: This gage is ideal for monitoring and controlling low differential pressure events (0 to 0.5" w.c.) in HVAC, clean room, filtration, or industrial automation setups where quick, reliable mechanical switching is needed.

Q: Where is Series 43000-0 best suited for installation?

A: This model is suitable for indoor industrial environments across India where air or compatible gases need monitoring, and where panel or surface mounting is practical. Its rugged aluminum case and clear acrylic dial ensure durability and visibility.

Q: What are the key benefits of having dual DPDT snap switches in this gage?

A: Dual set point DPDT snap switches allow users to set two independent switching thresholds, offering versatile control and alerting options for safety or process automation, all in one device.

Q: How accurate is the pressure measurement on this model?

A: The Series 43000-0 delivers high accuracy within 2% of full scale, making it suitable for applications where precise differential pressure monitoring is essential.

Q: Which accessories come with the Dwyer Series 43000-0 and how do they facilitate usage?

A: Each unit is supplied with mounting brackets and comprehensive wiring instructions, enabling straightforward installation and quick setup, even for panel-mount configurations.
