Pressure sensor
Load cells are used in all applications where you need to measure a load or force. Everything from weighing a truck (on a weighbridge) to measuring the force required to insert one component into another. Load cells (or force sensors) are often used in conjunction with LVDT displacement transducers, allowing the properties of a test specimen to be measured (i.e., how far it extends for a given force).
Pressure sensors are devices that convert the pressure of a liquid or gas into an electrical signal. The air line you use to inflate your car tires at the gas station, or the blood pressure monitor your doctor uses, both contain pressure sensors. There are many different types of pressure sensors, but ours work with a strain gauge that measures the deflection of a membrane under pressure changes.
