Force, Flex, Vibration Sensors

Clear

Flexiforce Pressure Sensor - 25lbs.

Code: SKU-000236

This is a piezoresistive force sensor from Tekscan. The harder you press, the lower the sensor’s resistance. Pressing hard, the resistance changes from infinite to ~300k. The sensor itself is thin and flexible, but the resistance does not change while being flexed.

Force-Sensing Resistor - 0.2" / 5mm Circle

Code: SEN-10039

This force-sensing resistor (FSR) from Interlink Electronics is a passive component that exhibits a decrease in resistance when there is an increase in the force applied to the 0.2" / 5mm active area, allowing you to create a sensor that is able to detect force or pressure. It can sense an applie...

Load Cell - 5kg, Straight Bar (TAL220B)

Code: SKU-004851

This straight bar load cell (sometimes called a strain gauge) can translate up to 5kg of pressure (force) into an electrical signal. Each load cell is able to measure the electrical resistance that changes in response to, and proportional of, the strain (e.g. pressure or force) applied to the bar.

Load Sensor - 50kg

Code: SKU-000630

This load sensor, sometimes called a strain gauge, is the same one found in digital bathroom scales (you know, the ones you use in January for your New Year’s resolutions, and then forget about a month later). This sensor can measure up to about 110 pounds.

Piezo Vibration Sensor - Large with Mass

Code: SKU-000350

This basic piezo sensor from Measurement Specialties is often used for flex, touch, vibration and shock measurements. A small AC and large voltage (up to +/-90V) is created when the film moves back and forth. A simple resistor should get the voltage down to ADC levels.

Piezo Vibration Sensor - Large PVDF Piezo Polymer Film

Code: SEN-10084

This piezo sensor can be used for measurement of shock, vibration, flex and touch. When bent or moved the piezoelectric material produces a large AC voltage up to +/-90V at low current. Suitable for use with analogue to digital converters on microcontrollers when a resistor is used.
