Load cells are transducers for force and load measurement, often with mounting packaging.

Impedance matching networks are electrical circuits which, when connected between two networks, match the output impedance of the source (the first network) to the input impedance of the load (the receiving or second network).

Force and load sensors covers electrical sensing devices used to measure tension, compression, and shear forces

Electronic loads and load banks are used to test electrical and electronic equipment.

Loading arms are used to load liquids into tanks, trucks, railcars, and other vehicles.

Bulk materials loaders and unloaders are used to fill and remove powders, granular substances and other bulk solids from bags, bins, boxes, carts, drums, hoppers, railcars, trucks, and silos.

Network load balancers are components that distribute interactive traffic across a number of hosts using dynamically updated rules for load balancing, while providing a single system image to the client system
