Pressure Sensor using Nano Strain Gauge

Principle of pressure measurements using strain gauge

Pressure is the force applied by a fluid or a solid to the surface of an object per unit area.
There are three types of pressure measurement: absolute (relative to the space), manometry (relative to atmospheric pressure) or differential (relative to a specific reference pressure).
The strain gauges allow realizing those three types of pressure measurement no matter if the pressures are low or high.
The pressure causes the deformation of an object. It is through this distortion, resulting into a resistance variation of the strain gauges, that the pressure will be measured.
This part is usually a membrane or a diaphragm which will bulge according to the difference of pressure between the outside and the inside of the sensor.

The strain gauges provide the link between the deformation of the diaphragm and the pressure measurement.

Sensor pressure using nano strain gauges

Nano strain gauge allow you to optimize the production of your sensors of pressure.

Their miniaturized active area allows you to realize very located pressure measurement on small part, difficult to access or narrow conducts.
Their high sensitivity (G=30), to measure very low pressure and so to build high precision sensors of pressure.
And their low power consumption, to make autonomous sensors.

Examples: pressure measurement

Pressure measurement in tanks is very common in the control of the manufacturing process in the food or pharmaceutical industry
Pressure measurement in silos allows manufacturers to manage better their stocks
Blood pressure measurement requires the use of strain gauges in catheters.
