Hydraulic Load Cell Definition

Miniature load cell hydraulic cells are force balance devices measuring weight as a change in pressure of the internal filling fluid.

Hydraulic load cell definition.

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. As the force increases the pressure of the hydraulic fluid increases. As the force applied to the load cell increases the electrical signal changes proportionally. All hydraulic scale types consist of one or more load cells and a means of translating the resultant pressure into a visible mass indication.

It converts a force such as tension compression pressure or torque into an electrical signal that can be measured and standardized. This pressure can be locally indicated or transmitted for remote indication or control. A load cell is a force transducer. A load cell is typically little more than a piston or diaphragm with a small oil filled compression chamber.

Hydraulic load cell applications can include tank bin and hopper weighing. 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. Compression load cell systems. In contrast to other solutions hydraulic load cells are safe from damage caused by lightning strikes or other electrical surges.
