2. Pressure switch - Wikipedia

   en.wikipedia.org/wiki/Pressure_switch

   A pressure switch will have a hysteresis, that is, a differential range around its setpoint, known as the switch's deadband, inside which small changes of pressure do not influence the state of the contacts. Some types allow adjustment of the differential. [1] The pressure-sensing element of a pressure switch may be arranged to respond to the ...

3. Air purge system - Wikipedia

   en.wikipedia.org/wiki/Air_purge_system

   Pressure switches are also used to indicate blower failure. The differential pressure trip is connected to the inlet and the outlet of the main filter of the air blower. Failure is indicated by a decrease in the differential pressure. The low-pressure trip connects to the main filter outlet.

4. DP cell - Wikipedia

   en.wikipedia.org/wiki/Dp_cell

   A DP cell is a device that measures the differential pressure between two inputs. [1]Example: To measure the pressure difference between a container (or vessel) and the surrounding atmosphere, you may connect 'Hi' port of the DP-cell to a fitting that enters the vessel, using suitable tubing.

5. Blower door - Wikipedia

   en.wikipedia.org/wiki/Blower_door

   An alternative approach to the multi-point procedure is to only measure fan airflow and building pressure differential at a single test point, such as 50 Pa, and then use an assumed pressure exponent, n Building in the analysis and generation of blower door metrics. This method is preferred by some for two main reasons: (1) measuring and ...

6. Pressure measurement - Wikipedia

   en.wikipedia.org/wiki/Pressure_measurement

   Differential pressure is the difference in pressure between two points. Differential pressure sensors are used to measure many properties, such as pressure drops across oil filters or air filters, fluid levels (by comparing the pressure above and below the liquid) or flow rates (by measuring the change in pressure across a restriction ...
