It converts a force such as tension compression pressure or torque into an electrical signal that can be measured and standardized.
Hydraulic load cell definition.
A load cell is typically little more than a piston or diaphragm with a small oil filled compression chamber.
Crown compression load cells often called pancake load cells are designed to give precise readings when compressed by a bulk tank deadline anchor or in other weight indication applications hydraulic compression load cells are ideally used in instances where electrical load cells may cause sparks and be potential explosion hazards.
In contrast to other solutions hydraulic load cells are safe from damage caused by lightning strikes or other electrical surges.
Miniature load cell hydraulic cells are force balance devices measuring weight as a change in pressure of the internal filling fluid.
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.
A load cell is a force transducer.
Hydraulic load cell applications can include tank bin and hopper weighing.
Compression load cell systems.
This pressure can be locally indicated or transmitted for remote indication or control.
All hydraulic scale types consist of one or more load cells and a means of translating the resultant pressure into a visible mass indication.
The most common types of load cell used are hydraulic pneumatic and strain gauge.
As the force increases the pressure of the hydraulic fluid increases.
