When a force is applied on a liquid medium contained in a confined space the pressure of the liquid increases.
Hydraulic load cell principle.
When a force is applied on a liquid medium contained in a confined space the pressure of the liquid increases.
Description of hydraulic load cell.
As the force increases the pressure of the hydraulic fluid increases.
The most common types of load cell used are hydraulic pneumatic and strain gauge.
This increase of the liquid is proportional to the applied force.
Hydraulic load cells they are force balance devices measuring weight as a change in pressure of the internal filling fluid.
This pressure can be locally indicated or transmitted for remote indication or control.
Principle of hydraulic load cell.
Strain gauge load cells.
Load cells are a type of transducer that determine the level of force applied to them and output this information as an electrical signal.
Hence a measure of the increase in pressure of the liquid becomes a measure of the appilied force when calibrated.
Most load cells use a strain gauge to detect measurements but hydraulic and pneumatic load cells are also available.
Hydraulic load cells miniature load cell hydraulic cells are force balance devices measuring weight as a change in pressure of the internal filling fluid.
The majority of load cells measure force using a strain gauge though versions using pneumatic or hydraulic systems are also available.
As the force applied to the load cell increases the electrical signal changes proportionally.

A load cell is a force transducer.
In hydraulic load cell a load or force acting on a loading head is transferred to a piston that in turn compresses a filling fluid confined within an elastomeric diaphragm chamber.
It converts a force such as tension compression pressure or torque into an electrical signal that can be measured and standardized.
In a rolling diaphragm type hydraulic force sensors a load or force acting on a loading head is transferred to a piston that in turn compresses a filling fluid confined within an elastomeric diaphragm chamber.
Hence a measure of the increase in pressure of the liquid becomes a measure of the applied force when calibrated.
This increase in pressure of the liquid is proportional to the applied force.
