Loadstar’s iLoad Mini sensor is based on the same Capacitive Technology as the iLoad and iLoad Pro sensors. However, it differs in one important respect–the Mini outputs a square wave whose frequency is proportional to the applied load.
The Mini, the smallest sensor currently offered by Loadstar Sensors, is a small circular sensor with a diameter of just 1.25 in. and has a load button on top of the sensor with a threaded stud in the middle, allowing it to measure push or pull load. It has three threaded holes on the bottom of the sensor to easily mount the sensor with commonly available hardware.
Unlike conventional resistive sensors based on either strain gauges or piezo-resistive techniques, Loadstar’s breakthrough patented technology harnesses changes in capacitance to measure loads quickly and accurately. In the Mini, the change in capacitance is converted into a change in frequency of the output signal.
The sensor accepts a 5V DC input and outputs a TTL square wave whose frequency is proportional to the applied load. Most data acquisition systems, microprocessors and microcontrollers have the capability to measure the frequency of the signal. Measures up to 10 lbs. capacity with an accuracy of 2 percent of full output.
Power requirement: regulated 5 V at 10 mA.
