Hydraulic load cells measure weight as a change in pressure of the internal fluid.
Hydraulic load cell definition.
All hydraulic scale types consist of one or more load cells and a means of translating the resultant pressure into a visible mass indication.
A load cell is a force transducer.
Compression load cell systems.
It converts a force such as tension compression pressure or torque into an electrical signal that can be measured and standardized.
Miniature load cell hydraulic cells are force balance devices measuring weight as a change in pressure of the internal filling fluid.
As the force increases the pressure of the hydraulic fluid increases.
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.
The most common types of load cell used are hydraulic pneumatic and strain gauge.
This pressure can be locally indicated or transmitted for remote indication or control.
In contrast to other solutions hydraulic load cells are safe from damage caused by lightning strikes or other electrical surges.
As the force applied to the load cell increases the electrical signal changes proportionally.
Hydraulic load cell applications can include tank bin and hopper weighing.
