Duct Static Pressure Sensors

Static pressure sensors the a 300 series sensors are used with pressure transmitters and pressure switches to sense duct pressures.

Duct static pressure sensors.

The h port senses total pressure and the l port senses static pressure the difference between these signals is differential or velocity pressure. These sensor are normally used in conjunction with the vav 1000 2000 and 3000 series vav terminal controllers for individual zone control in hvac systems. Two sensors are required to monitor pressure across coils filters blowers etc. 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.

Kele carries duct static pressure sensors and pressure accessories to fit your specifications. Air handler filter pressure sensor duct static pressure sensor this air handler provides air to ddc variable air volume systems. A 301 and a 302 have four radial sensing holes and 4 10 2 cm insertion depth. The pressure sensors shown in the photo filter pressure sensor and low static pressure and two additional pressure sensors.

So the air flow provided by the air handlers will modulate based on what the need of the vav boxes require and what the duct static pressure sensor is reading. Duct static sensors pressure kele. Temperature humidity dew point co voc s pressure and low temperature limit detection.
