Omron D6F-PH Differential Pressure Sensor
Omron D6F-PH Series Differential Pressure Sensor is a new type of MEMS chip with I ²C digital output. Using Omron proprietary MEMS mass flow technology, the sensor features a redesigned internal flow path that produces low flow, high velocity/high impedance for a differential pressure output. Because the sensor is not sensitive to variations in bypass tube length, D6F is ideal for HVAC applications which involve field-installed damper controls. SUBSCRIPTION CENTER - Mouser's Newest...

Spend Your Time Engineering, Not on Differential Equations
with something as simple as a spring-mass-damper system, for example, users must draw the free body diagram and then generate the governing equations between the physical components. Next, users must derive the differential equations for the system, convert them to integral form, and, finally, break
