Duct Static Pressure Switch

Duct pressure switches automatically start and stop auxiliary devices like electronic air cleaners duct heaters humidifiers exhaust fans and duct booster fans.

Duct static pressure switch.

Static pressure is a drag literally. 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. Rely on grainger for a wide range of duct pressure switch options. Pl liquid pressure sensors switches monitor flow and prove pumps chillers and valves.

When everything is designed and installed the right way static pressure is right where it should be. An optional discharge air static high limit reduces the fan speed if discharge static pressure increases above its setpoint. Hvac systems regardless of size are designed to move a certain amount of air. Duct pressure switches automatically start and stop auxiliary devices like electronic air cleaners duct heaters humidifiers exhaust fans and duct booster fans.

The model 1900 5 mr measures static pressure only not differential pressure. Order the a 399 duct pressure kit separately. Belimo offers a broad range of air duct sensors covering all standard measurement values. On a call for full pressure the fan runs at full speed.

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. With over 1 8 million parts in stock kele makes it easy to avoid project delays. Kele carries duct static pressure sensors and pressure accessories to fit your specifications. An air switch senses positive negative or differential air pressure and actuates an internal switch.

Ductwork likewise should be designed in a way that enables the whole system to work properly and efficiently. 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. 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. Switch contacts are spdt with solder type connections.

As duct static pressure increases the supply fan speed reduces. These sensors can be used to measure static pressure in a large range of liquids and gases. Temperature humidity dew point co voc s pressure and low temperature limit detection. The switch must be manually reset before the system can start again.

Rely on grainger for a wide range of duct pressure switch options. Duct static control specifications are taken directly from vendors standard specifications.
