Duct Static Pressure Switch

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.

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. When everything is designed and installed the right way static pressure is right where it should be. Temperature humidity dew point co voc s pressure and low temperature limit detection. An optional discharge air static high limit reduces the fan speed if discharge static pressure increases above its setpoint.

Ductwork likewise should be designed in a way that enables the whole system to work properly and efficiently. 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. Static pressure is a drag literally. Order the a 399 duct pressure kit separately.

An air switch senses positive negative or differential air pressure and actuates an internal switch. Duct pressure switches automatically start and stop auxiliary devices like electronic air cleaners duct heaters humidifiers exhaust fans and duct booster fans. Belimo offers a broad range of air duct sensors covering all standard measurement values. Kele carries duct static pressure sensors and pressure accessories to fit your specifications.

The switch must be manually reset before the system can start again. The model 1900 5 mr measures static pressure only not differential pressure. On a call for full pressure the fan runs at full speed. Pl liquid pressure sensors switches monitor flow and prove pumps chillers and valves.

Kele is the leading supplier of building automation products. With over 1 8 million parts in stock kele makes it easy to avoid project delays. These sensors can be used to measure static pressure in a large range of liquids and gases. 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.

Hvac systems regardless of size are designed to move a certain amount of air. An air switch senses positive negative or differential air pressure and actuates an internal switch. Duct static control specifications are taken directly from vendors standard specifications. Switch contacts are spdt with solder type connections.

Rely on grainger for a wide range of duct pressure switch options. As duct static pressure increases the supply fan speed reduces.
