A load cell is an electronic device (transducer) that is used to convert a force into an electrical signal. This conversion is indirect and happens in two stages. Through a mechanical arrangement, the force being sensed deforms a strain gauge. The strain gauge converts the deformation (strain) to electrical signals. A load cell usually consists of four strain gauges in a Wheatstone bridge configuration. Load cells of one or two strain gauges are also available. The electrical signal output is typically in the order of a few millivolts and requires amplification by an instrumentation amplifier before it can be used. The output of the transducer is plugged into an algorithm to calculate the force applied to the transducer.
Sensitivity (mV/V) = Full Scale Output (mV) / Excitation Voltage (V)
mV = milli Volt
V = Volts
Standard sensitivities are 2 mV/V and 3 mV/V
Example:
For a load cell with 10V excitation has 20 mV full scale output, sensitivity is 20mV / 10V i.e. 2mV/V.

∙ 14y agoLoad sensitivity is the ability to sense and to compensate for changes in the load. A voltage regulator, for instance, provides a current flow into a node of a circuit and monitors the voltage at the node. If the circuit connected to that node (the load) were to start drawing more current, the voltage at that node would drop. The regulator would sense this and compensate by providing more current, restoring the voltage to the correct value.

How many types of load cell?
I think there are 4 types of load cells they are Pancake Load CellS ,Beam Load CellLoad, ButtonSingle and Point Load Cell.
Which is better Compression load cell or double ended shear beam load cell?
Dear actually it depend on its application. Where do you want to use them.. Compression Load Cell is considered as one of the best and long performance load cell. and Double Ended shear beam load cell is widely known for its smooth operations.
What are input impedance in a load cell?
The resistance measured across the excitation terminals of the load cell, when the output terminals are open.
What is pneumatic load cell?
Pneumatic Load Cells - this is another type of a mechanical load cell. It has a wide weight range and a high accuracy. On the plus side they are intrinsically safe and it contains no fluids but on the downside they have a slow response rate and they need to be cleaned regular with dry air. These types of load cells are usually used in the food industry and hazardous areas.
How to find out the output voltage across the load cell?
by connecting a multimeter u can measure

What is compressive and tension load cell?
In compressive load cell weight is applied on load cell and it gets compressed. Due to this compression we can measure the applied load. You can check out at http://www.adiartech.com/compression90210.html and in tension load cell see this link that i came across http://www.adiartech.com/loadcells.html
What is a pressductor?
load cell
What is the input and output of a load cell?
The input of a load cell is the force or weight applied to it. The output of a load cell is an electrical signal, typically in the form of voltage or current, that is proportional to the applied force or weight.
Easy way to learn how the human cell works?
the human cell secretes,excretes,respires.reproduces,shows sensitivity
What are input impedance in a load cell?
The resistance measured across the excitation terminals of the load cell, when the output terminals are open.
What disorder by reduced sensitivity of insulin's target cell?
types II diabetes
Does a 357 rifle have a strong recoil?
Depends on your sensitivity to recoil and the type of rifle and load used. Generally, not bad at all.
What does the term load cell mean?
A load cell is a transducer which converts force into a measurable electrical output. Although there are many varieties of load cells, strain gage based load cells are the most commonly used type.
What does load cell used?
It used loads for it.
