Dwyer A-489 static pressure tip is suitable for use with manometers, gauges, controllers and pressure switches for monitoring static pressure drop across cooling coils, air filters, discharge pressures & blower inputs.
Features:
- Dwyer A-489 static pressure tip comes with a mounting flange having dual screws and an integral rubber gasket for simplifying duct mounting & hassle-free maintenance.
- It features stainless steel construction to offer high strength and withstand abrasive industrial conditions.
- This unit has an angled tip having a 4-inch insertion depth and four radial sensing holes of 0.040 inches.
Frequently Asked Questions:
Q. How do you use a static pressure tip?
A. To gain access to the air stream, install a test port. Directly place the static pressure tip's pointed end into the airflow. Another pressure in the duct system known as velocity pressure is split up by the pointed tip and directed away from the nearby tiny holes.
Q. What is the difference between a static pressure sensor and a differential pressure sensor?
A. A differential pressure sensor, often known as a DP sensor, is a unique kind of pressure sensor that gauges the difference in pressure between two ports on a device. It is distinct from a static or absolute pressure sensor that uses a single port to measure pressure.
Q. How do you increase static pressure in HVAC?
A. Static pressure will rise with more obstructions or faster air, which includes control dampers. Your dampers could not open or close as needed if the duct is under too much pressure.
