Piezo Sensor Applications

Piezo sensors are used to measure the change in pressure, acceleration or strain by converting them into electrical charge. They offer very high sensitivity which makes them very well suited to applications within patient monitoring.  Piezo Sensor Applications Piezo sensors are used for...

What is a Linear Potentiometer?

Linear potentiometers are often rod actuated and connected to an internal slider or wiper carrier. The rod will be connected to a device or object which requires measurement. The linear potentiometer proportionally divides an applied regulated voltage over its operational range and provides a...

What is an LVDT?

LVDT stands for Linear Variable Differential Transformer, the device is constructed of a primary coil, one or two secondary coils, a ferromagnetic core (or slug), a tube or bobbin, a shield and a shaft. The ferromagnetic core is attached to a moving object and moves in a linear motion within the...

What is a Strain Gauge?

The resistance of a strain gauge changes when force is applied and this change will give a different electrical output. Strain gauges use this method to measure pressure, force, weight and tension. When external forces are applied to a stationary object there are two forces present; stress and...
