Dwyer Series 43002 Capsu-Photohelic Pressure Switch Gage0-2.0" w.c.

Model	Description
43002	Pressure Switch/Gage, Range 0-.2.0" 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.

Equipped with mounting hardware and a comprehensive instruction manual, the unit requires no external power for switching and can be reset both manually and automatically.

FAQs of Dwyer Series 43002 Capsu-Photohelic Pressure Switch Gage 0-2.0" w.c.:

Q: How is the Dwyer Series 43002 Capsu-Photohelic Pressure Switch Gage installed?

A: The Series 43002 is installed using the provided mounting hardware and can be either panel or surface mounted. For piping, it features two 1/8" NPT female process connections, making integration easy for air or compatible gas pressure measurements.

Q: What types of applications benefit most from this pressure switch gage?

A: This gage is ideal for HVAC systems, clean room monitoring, filtration equipment, and process industries that require precise low differential pressure control and monitoring of non-combustible gases.

Q: When should the manual or automatic reset options be used?

A: Use the manual reset when a process requires deliberate operator intervention after a setpoint trip. The automatic reset is suitable for continuous monitoring applications where the switch needs to respond instantly to changing pressure conditions without manual resetting.

Q: Where can the Series 43002 be operated safely?

A: It is designed for indoor use only, within environments covered by the NEMA 4X protection rating, and operates efficiently in temperatures ranging from 20 to 120F (-6 to 49C).

Q: What is the process of setting pressure setpoints on this gage?

A: Pressure setpoints are configured using the adjustable dials on the front analog display (Photohelic scale). These setpoints correspond to the desired switch activation points and are factory calibrated for ease of setup.

Q: What maintenance is required for the Capsu-Photohelic Pressure Switch Gage?

A: Routine visual inspection for leaks or physical damage is recommended. Calibration is provided by the factory, but periodic functional checks in accordance with application requirements help maintain accuracy.

Q: How does this gage benefit industrial operations?

A: It offers instantaneous switch response, robust construction, reliable accuracy (2% full scale), and dual switch control. This enhances system safety, ensures efficient process control, and reduces downtime due to its low maintenance demands.
