| Kele RPS | Pressure | Pressure Accessories

Duct pressure sensors A-301-K and A-302-K are used with pressure transmitters and pressure switches. Two sensors are required to monitor pressure across coils, filters, blowers, etc. The A-301-K and A-302-K have four radial sensing holes and 4" ( cm) insertion depth. The A-308-K should be used only where accuracy is not critical.

8 Automated Building Applications - Pressure Sensors - The ...

Differential pressure sensors are also used to measure the relative pressure differences between duct air and room air. Air pressure differences can cause various issues in a building, normally attributed to either a positive or negative air pressure difference. For example, a negative air pressure in one part of a building will cause air currents, as the relatively higher pressures find their ...
