Omron D6F-PH Differential Pressure Sensor

Omron D6F-PH Series Differential Pressure Sensor is a new type of MEMS chip with I²C 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.

The D6F-PH is a thermal flow-type sensor meaning it is capable of measuring with superior sensitivity and reproducibility in low pressure environments and with a wider pressure range than the commonly-used capacitance-type and piezoelectric-type differential pressure sensors. Embedded ASICs carry out digital correction (linearity and temperature correction) making the D6F-PH more precise and less influenced by temperature than conventional analog output sensors.

The D6F-PH will make it possible to optimize business and household air conditioning and ventilation control in order to maximize energy efficiency, and also, for example, increase the accuracy of gas flow control and monitoring in digital medical equipment such as anesthetic machines and respirators.
