Hydraulic Load Cell Principle

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.

Hydraulic load cell principle.

Hydraulic load cells miniature load cell hydraulic cells are force balance devices measuring weight as a change in pressure of the internal filling fluid. Hydraulic load cell principle common principle of hydraulic load cell when a force is applied on a liquid medium contained in a confined space the pressure of the liquid increases. As the force increases the pressure of the hydraulic fluid increases. The working principle of a compression load cell a load cell is a transducer that measures force and outputs this force as an electrical signal.

Most load cells use a strain gauge to detect measurements but hydraulic and pneumatic load cells are also available. When a force is applied on a liquid medium contained in a confined space the pressure of the liquid increases. This pressure can be locally indicated or transmitted for remote indication or control. 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.

When a force is applied on a liquid medium contained in a confined space the pressure of the liquid increases. This increase of the liquid is proportional to the applied force. This increase in pressure of the liquid is proportional to the appilied force. Load cells are a type of transducer that determine the level of force applied to them and output this information as an electrical signal.

Principle of hydraulic load cell. This increase in pressure of the liquid is proportional to the applied force. A load cell is a force transducer. Hence a measure of the increase in pressure of the liquid becomes a measure of the applied force when calibrated.

Basic priniple of hydraulic load cell when a force is applied on a liquid medium contained in a confined space the pressure of the liquid increases. It converts a force such as tension compression pressure or torque into an electrical signal that can be measured and standardized. Description of hydraulic load cell. The majority of load cells measure force using a strain gauge though versions using pneumatic or hydraulic systems are also available.

Hence a measure of the increase in pressure of the liquid becomes a measure of the appilied force when calibrated. The most common types of load cell used are hydraulic pneumatic and strain gauge.
