Duct Static Pressure Switch

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

Duct static pressure switch.

Rely on grainger for a wide range of duct pressure switch options. An optional discharge air static high limit reduces the fan speed if discharge static pressure increases above its setpoint. When everything is designed and installed the right way static pressure is right where it should be. As duct static pressure increases the supply fan speed reduces.

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. Temperature humidity dew point co voc s pressure and low temperature limit detection. An air switch senses positive negative or differential air pressure and actuates an internal switch. Switch contacts are spdt with solder type connections.

Duct pressure switches automatically start and stop auxiliary devices like electronic air cleaners duct heaters humidifiers exhaust fans and duct booster fans. With over 1 8 million parts in stock kele makes it easy to avoid project delays. Static pressure is a drag literally. Duct static control specifications are taken directly from vendors standard specifications.

Kele carries duct static pressure sensors and pressure accessories to fit your specifications. Air dp sensors switches air dp switches for fan proving single or multi range air dp sensors for dirty filter monitoring and air flow or pressure control. Order the a 399 duct pressure kit separately. Rely on grainger for a wide range of duct pressure switch options.

Ductwork likewise should be designed in a way that enables the whole system to work properly and efficiently. An air switch senses positive negative or differential air pressure and actuates an internal switch. Belimo offers a broad range of air duct sensors covering all standard measurement values. Static pressure sensors are for use with pressure gages switches transmitters and other controllers to pick up or sense static pressure drop across air filters and cooling coils blower input and discharge pressures etc.

To maintain the static pressure set point the supply fan will modulate appropriately but the set point is usually determined based on design conditions before the building is ever built. These sensors can be used to measure static pressure in a large range of liquids and gases. Duct pressure switches automatically start and stop auxiliary devices like electronic air cleaners duct heaters humidifiers exhaust fans and duct booster fans. Pl liquid pressure sensors switches monitor flow and prove pumps chillers and valves.

Hvac systems regardless of size are designed to move a certain amount of air. Kele is the leading supplier of building automation products.
