FAQs of Dwyer ADPS-03-2-N Adjustable Differential Pressure Switch:

Q: How do I adjust the set point on the ADPS-03-2-N differential pressure switch?

A: You can adjust the set point by turning the knob located beneath the cover. This allows pressure adjustment within the 0.05 to 0.25 in WC (12 to 62 Pa) range, ensuring the switch operates according to your systems requirements.

Q: What types of media can the Dwyer ADPS-03-2-N measure?

A: This model is designed to measure differential pressure of air and compatible gases, making it suitable for HVAC systems, industrial air handling, and similar applications.

Q: Where is the ADPS-03-2-N typically installed?

A: It is intended for wall or panel mounting, with all necessary accessories included. The enclosures compact size and IP54 rating allow for placement in industrial environments where dust and moisture protection is beneficial.

Q: What is the process for connecting the pressure lines to the switch?

A: Attach the two provided plastic tubes to the barbed fittings, accepting 6 mm outer diameter tubing. Connect one to the high-pressure (HI) port and the other to the low-pressure (LO) port to allow the device to monitor the pressure differential.

Q: What are the benefits of using the ADPS-03-2-N in industrial applications?

A: The switch offers dependable switching action, adjustable set points, and resilient ABS construction. Its compact design, ease of installation, and reliability make it an excellent choice for industrial and automation systems.

Q: How is electrical connectivity handled for this pressure switch?

A: The ADPS-03-2-N uses a SPDT snap switch rated 5A at 250 VAC, allowing integration with various control systems for monitoring or safety shutdown applications.

Q: When should the ADPS-03-2-N pressure switch be used instead of a pressure sensor with display?

A: This switch is ideal when only a switching response is needed, rather than continuous monitoring or reporting. It offers cost effectiveness and simplicity for safety triggers or control logic in ventilation or filter monitoring applications.
