Duct Static Pressure Sensor Symbol

All electric ddc duct static pressure control the controller uses a static pressure sensor located in the supply duct at the end of the longest run to modulate the supply fan to control duct static pressure.

Duct static pressure sensor symbol.

On a call for full pressure the fan runs at full speed.

As duct static pressure increases the supply fan speed reduces. Kele carries duct static pressure sensors and pressure accessories to fit your specifications.

Vav damper positions vs. 32003169 001 static pressure probe. The probe has two orifices vertically opposite each other that cancel out any airflow induced errors. Temperature humidity dew point co voc s pressure and low temperature limit detection.

This is an indicator that the static pressure set point is too high 2. Duct sizing 13 8 1 constant friction loss method 14 8 2 velocity reduction method 17 8 3 static regain method 19 9 0. There are eight zones that this air handler serves and all of the dampers are less than 50 open during this day. When measuring static pressure the unit of measurement used is inches of water column which is often shown as an abbreviation such as in.

Static pressure is exerted equally on all sides of a duct system. 7 2 maintaining neutral pressure 13 8 0. The touch interface allows for quick and easy menu driven. Belimo offers a broad range of air duct sensors covering all standard measurement values.

Time too high duct static pressure set point. Exhaust duct up ct ct m mvd 48 a f f. The following air sensor symbols snap to all horizontal ducts from the ductwork symbols. The static pressure probe is designed to pick up static pressure in a duct plenum air handler or other hvac equipment.

With over 1 8 million parts in stock kele makes it easy to avoid project delays. Duct construction reinforcement 20 9 1 duct sheet metal thickness 20 9 2 duct hanger spacing 21 10 0. Recommended practices for ducting layout 21 10 1 zoning 22. This pressure is similar to that found by blowing up a balloon.

The heart of the unit is a micro machined silicon pressure sensor with excellent accuracy repeatability and stability.
