, Measuring devices
Transducers are devices that are able to convert energy from one to another,
meaning that some transducers can convert electrical energy into mechanical
energy, and vice versa. But there are also transducers that does both. These
devices are used for measurements or information transfer.
The measurement devices are:

Multi-meters
Data logger
