The iLoad Mini Pro Series load cell is designed for applications where size is a major constraint. The iLoad Mini Pro is only 2.0″ in diameter and outputs a 5V TTL square wave whose frequency
is proportional to applied loads.

Loadstar’s iLoad Mini Pro load cells are similar to the iLoad Mini load cells in almost every respect, but are meant for higher capacity applications. They come in the dome version for compression force measurements and in the threaded stud version for tension force measurements and for universal (compression and tension force) measurements.
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.

If one wants an analog (0.5 V—4.5V or 2mV/V) or digital USB out put from the iLoad Mini the DQ-1000A, DQ1000U or DQ-4000U are available options.
