A load Phidget load cell is a force sensing device/module accurately designed metal structure, with a trivial element known strain gauges mounted in exact locations on the device. Load cells are also designed to record/measure a particular force while ignoring external force applied to the system. The electrical signal input induced by the load cell is very minimum and requires a specialized amplification. Providentially, Phidget bridge interfaces will always perform all the system amplification and measurement of all electrical output. If you are to buy a load cell, try to assess the compatibility and connection tabs for more details and its purpose.
Load cells are also customized to measure force in a unidirectional. Most of the market designs always measure force in other directions; however, the sensor sensitivity can vary. It is also wise to understand that most operating cells can induce compression, giving tension output.
Uses of Load Cell
The application of load cell is widely used in kitchen and jewelry scales. The cell is mounted by fixing or mounting down the cell’s end where the wires are fixed and the applying force on the other end in the opposite direction of the system’s arrow. The external force is not that important, as this load design helps measure the shearing effect on the scale beam and not the bending beam. If you try to mount a sizable platform on the system, the load cell will provide an accurate reading despite the system’s position.
Connection
In order to connect a load cell, you need a power source that will drive the cell to produce a small connecting or differential voltage when operating under strain. If you read the input signal, the board or the amplifier is required, but this extension should be accurate or customized to give a high reading scale from an analog-to-digital system. You can read more about the system’s connectivity and usage by checking the compatibility and connection tab.
Before buying or installing your Phidget load cell, try to calibrate your device; you can find more calibration information on setting or calibrate your device in the load cell primer. You should also try to look for the original user’s guide for all bridge interface systems to understand power usage, connection ability, and system compatibility. In conclusion, with the number of designs out there, you need to scrutinize all the options available and pick something that fits your system applications.
