Kele carries duct static pressure sensors and pressure accessories to fit your specifications.
Duct static pressure switch.
On a call for full pressure the fan runs at full speed.
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.
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.
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.
Belimo offers a broad range of air duct sensors covering all standard measurement values.
Kele is the leading supplier of building automation products.
These sensors can be used to measure static pressure in a large range of liquids and gases.
The dwyer model 1900 5 mr manual reset pressure switch is designed to monitor duct static and shut down the blower when excess pressure occurs.
Duct static control specifications are taken directly from vendors standard specifications.
Pl liquid pressure sensors switches monitor flow and prove pumps chillers and valves.
Order the a 399 duct pressure kit separately.
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.
An air switch senses positive negative or differential air pressure and actuates an internal switch.
Rely on grainger for a wide range of duct pressure switch options.
Duct pressure switches automatically start and stop auxiliary devices like electronic air cleaners duct heaters humidifiers exhaust fans and duct booster fans.
An optional discharge air static high limit reduces the fan speed if discharge static pressure increases above its setpoint.
Rely on grainger for a wide range of duct pressure switch options.
Temperature humidity dew point co voc s pressure and low temperature limit detection.
Switch contacts are spdt with solder type connections.
As duct static pressure increases the supply fan speed reduces.
Duct pressure switches automatically start and stop auxiliary devices like electronic air cleaners duct heaters humidifiers exhaust fans and duct booster fans.
Static pressure is a drag literally.
The model 1900 5 mr measures static pressure only not differential pressure.
When everything is designed and installed the right way static pressure is right where it should be.
With over 1 8 million parts in stock kele makes it easy to avoid project delays.
Hvac systems regardless of size are designed to move a certain amount of air.
