Duct Static Pressure Switch

The switch must be manually reset before the system can start again.

Duct static pressure switch.

An air switch senses positive negative or differential air pressure and actuates an internal switch. 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. Pl liquid pressure sensors switches monitor flow and prove pumps chillers and valves. With over 1 8 million parts in stock kele makes it easy to avoid project delays.

Duct pressure switches automatically start and stop auxiliary devices like electronic air cleaners duct heaters humidifiers exhaust fans and duct booster fans. Temperature humidity dew point co voc s pressure and low temperature limit detection. Rely on grainger for a wide range of duct pressure switch options. As duct static pressure increases the supply fan speed reduces.

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. Rely on grainger for a wide range of duct pressure switch options. The model 1900 5 mr measures static pressure only not differential pressure. An air switch senses positive negative or differential air pressure and actuates an internal switch.

Kele is the leading supplier of building automation products. Order the a 399 duct pressure kit separately. 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.

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 pressure switches automatically start and stop auxiliary devices like electronic air cleaners duct heaters humidifiers exhaust fans and duct booster fans. These sensors can be used to measure static pressure in a large range of liquids and gases. Kele carries duct static pressure sensors and pressure accessories to fit your specifications.

Hvac systems regardless of size are designed to move a certain amount of air. An optional discharge air static high limit reduces the fan speed if discharge static pressure increases above its setpoint. 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. Ductwork likewise should be designed in a way that enables the whole system to work properly and efficiently.

Static pressure is a drag literally. Switch contacts are spdt with solder type connections.
