You can know the load on an electric motor by measuring the electric current going to the motor (Amps). But, this is not the best way to do it since a lightly-loaded motor doesn't use the electricity very efficiently. (In technical terms, the power factor is low.)

A better way to know the load is to measure the motor power. (Power is measured in Horsepower or Watts.) Motor power gives you a straight line so it works well even when the motor is lightly loaded.

The Power Sensors that we make measure the motor load (Horsepower or Watts) and send a signal to meters or computers. The operator can see what the status is on the meter or, the computer can make decisions.
