Load Cell


 

Product Specification:

 

A load cell is a transducer that is used to convert a force into electrical signal. This conversion is indirect and happens in two stages. Through a mechanical arrangement, the force being sensed deforms a strain gauge. The strain gauge converts the deformation (strain) to electrical signals. A load cell usually consists of four strain gauges in a Wheatstone bridge configuration. Load cells of one strain gauge (quarter bridge) or two strain gauges (half bridge) are also available. The electrical signal output is typically in the order of a few millivolts and requires amplification by an instrumentation amplifier before it can be used. The output of the transducer is plugged into an algorithm to calculate the force applied to the transducer."

 

Double Ended Shear Beam:

This is constructed from electro less nickel plated heat treated tool steel suitable for harsh applications. Cup and steel ball mounted mechanism is self-restoring and self-centering. Transient voltage protection is provided for protection against lightning and line voltage faults.
