Flow sensors offer low-cost implementatino
Omron's D6F series of MEMS flow sensors uses an element called a thermopile that converts thermal energy into electrical energy.
Omron Electronic Components has released the D6F series of MEMS flow sensors which have the ability to measure flow speed from 1mm/s to 40m/s.
This is the industry's first flow sensor to use an element called a thermopile that converts thermal energy into electrical energy.
This new method delivers a variety of advantages, including low-cost implementation (no adjusting required), low power consumption, accurate measurement and high sensitivity.
Conventional flow sensors use a resistance measurement method by tracking the electrical resistance change of a material due to changes in temperature.
This method requires a labor-intensive adjustment of the resistance balance.
The D6F operates from -10 to 60C with a supply voltage of 12 to 24V dc while consuming just 15mA.
It has an integral orifice with an analogue output of 1 to 5V dc and measures 15 x 20 x 60mm.
The D6F series is ideal for oxygen concentrators, inhaled anesthetics, heliox, CPAP, and ventilator applications.
"Omron's engineering team overcame many obstacles developing the D6F MEMS sensors, bringing the latest thermopile technology to designers while delivering compact, low-cost, high precision air flow sensors", said Cami Marsh, Omron Electronic Components.
