Dwyer Instruments ADPS-08-2-N Pressure Switch
The Dwyer Instruments ADPS-08-2-N is a precision-engineered differential pressure switch designed for monitoring pressure, vacuum, and differential pressure in HVAC and automation systems. Operating within a range of 0.08" to 1.2" W.C., this adjustable switch is optimized for air and non-combustible gases, making it essential for filter monitoring, fan status indication, and frost protection in heat exchangers. The unit features an SPDT switch (Single Pole Double Throw) configuration, allowing for versatile wiring to trigger alarms or control fans based on setpoint thresholds. Its compact housing includes a 5/16" O.D. tubing connection, compatible with standard 1/4" I.D. tubing, and requires vertical mounting for accurate sensing and calibration. The silicone diaphragm and glass-filled polycarbonate body ensure durability in demanding commercial environments, while the easy-to-access adjustment knob allows for precise field tuning of the setpoint across the specified pressure range.
Key Technical Benefits:
- Field Adjustable Setpoint: Integrated adjustment knob allows for precise calibration between 0.08" and 1.2" w.c. without external gauges.
- Versatile SPDT Logic: Simplifies integration into Building Automation Systems (BAS) for normally open or normally closed configurations.
- Standardized Plumbing: Features dual 5/16" O.D. pressure ports that seamlessly interface with 1/4" I.D. flexible tubing.
- Industrial Durability: Rated for up to 10,000 cycles with a robust silicone diaphragm and flame-retardant housing.
- Compact Form Factor: Designed for modern air handling units where mounting space is limited but accuracy is critical.
Professional Insights & Common Questions:
How do I handle mounting orientation for the ADPS series?
To maintain the stated setpoint accuracy, the ADPS-08-2-N must be installed with the diaphragm in a vertical position. If mounted horizontally, the weight of the internals may cause a slight shift in the switching pressure setpoint.
Which gases are compatible with this differential pressure switch?
This device is rated specifically for air and non-combustible gases. Using this with corrosive or flammable media will result in diaphragm failure and potential safety hazards.
What is the maximum pressure rating for this switch?
The unit is designed for low-pressure applications with a maximum pressure rating of 40" w.c. (10 kPa). Exceeding this limit can cause permanent deformation of the internal silicone sensing element.
