Force senor, Flex sensor, pressure Sensors at affordable cost - Xbotics
This straight bar load cell (sometimes called a strain gauge) can translate up to 5 kg 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.
The MPX10DP is a dual-port uncompensated silicon Pressure Sensor for environmental control systems and level indicators. The MPX10 series silicon piezoresistive pressure sensor provides a very accurate and linear voltage output, directly proportional to the applied pressure.
