An example of an electrical force gauge is an "electronic scale". One or more electrical load cells (commonly referred to as "weigh bars") are used to support a vertical or horizontal "live load" and are solid-state potentiometers which have variable internal resistance proportional to the load they are subjected to and deflected by.
A 'brake' dynamometer applies variable load on the prime mover (PM) and measures the PM's ability to move or hold the RPM as related to the "braking force" applied. It is usually connected to a computer that records applied braking torque and calculates engine power output based on information from a "load cell" or "strain gauge" and a speed ...
Single Point load cells; used in small to medium platform scales with platform sizes of 200x200mm up to 1200x1200 mm. Planar Beam load cells; used in low profile solutions where space is limited, like medical scales and retail scales. Bending Beam load cells; used in pallet, platform and small hopper scales.
A Safe Load Indicator (SLI) or an Automatic Safe Load Indicator (ASLI) is a device which is installed on mobile or portal cranes to alert the operator if the lift is exceeding the safe operating range of the machinery. [1] In some cases, the device will physically lock the machinery in circumstances it determines to be unsafe.
A machine-tool dynamometer is a multi-component dynamometer that is used to measure forces during the use of the machine tool. Empirical calculations of these forces can be cross-checked and verified experimentally using these machine tool dynamometers .
Greco-Roman Trispastos ("Three-pulley-crane"), a simple crane type (150 kg load) A crane for lifting heavy loads was developed by the Ancient Greeks in the late 6th century BC. [7] The archaeological record shows that no later than c. 515 BC distinctive cuttings for both lifting tongs and lewis irons begin to appear on stone blocks of Greek ...
A chassis dynamometer, informally referred to as a rolling road [1] or a dyno, is a mechanical device that uses one or more fixed roller assemblies to simulate different road conditions within a controlled environment, and is used for a wide variety of vehicle testing and development purposes. All Wheel Drive Chassis Dynamometer
"Dynamo Electric Machine" (end view, partly section, U.S. patent 284,110) A dynamo is an electrical generator that creates direct current using a commutator.Dynamos were the first electrical generators capable of delivering power for industry, and the foundation upon which many other later electric-power conversion devices were based, including the electric motor, the alternating-current ...
