Current transducers are responsible for providing DC current and voltage output that are directly proportionate to the AC input current. AC current transducers typically have an input that is designed to isolate the power source in a transducer and act as the main transformer for electronics.
AC Current Transducers Are Typically Divided Into Two Main Types
Absolute Average Measuring Transducer
This type of transducer is RMS calibrated and this means that it delivers a value measurement format that is calibrated to RMS values. These are often the inexpensive version of transducers because they work to convert the AC energy into DC current and the output calibration is designed to match the root mean square of the sine wave input. This type of transducer is adequate for a variety of equipment that is not typically sensitive. If there is a need for regular power output in which the wave shape can be distorted, this can provide decent power generation without the option for completely consistent results. With harmonic discontinuities that can occur, these types of transducers can sometimes create error messages on sensitive medical equipment and some electronics. For running most types of heavy machinery and for a variety of industrial tasks, this measuring type can be extremely useful and also quite inexpensive to utilize.
True RMS Transducers
This style of transducer calculates the RMS value based on the current input and then provides a DC output which is proportional to the value of that input. It is very little in the way of distortion and this device will always produce the same current output based on the settings associate don the model. These are the types of systems that are perfect for running more sensitive equipment and for providing consistency in results. If you regularly experience power fluctuations that could damage sensitive equipment, these types of transducers are often the better choice for managing current and for handling more sensitive equipment.
Both of these transducer types can be particularly effective at running a variety of machinery and electronics. Whether you need to handle output conversion for motor technology, heavy equipment or electronics, these are transformer devices that can have their own individual uses and their own benefits. Saving money from a true RMS transducer can often be wise if you are going to be running equipment that does not require extensive precision in its power input. Opting for True RMS is often a requirement for any type of highly sensitive equipment.
