Current Transformers are similar to Donut Current transformers, except that
the Transformers have terminals instead of secondary leads. These are ideal for
use with a digital AC Ammeter, and can be conveniently mounted to a panel or
fixture.
Current Transducers monitor high AC Current signals and emit a 4-20 mA
signal. This signal can be sent over long distances (up to 1000') to a digital
Process Indicator in a remote location.
