# Current Converter

The passage of electric charge is known as electric current. The ampere (A), which is one coulomb of cost per second, is the SI unit of electric current.

## Electric current measurement units

Amperes, milliamperes, kiloamperes, megaamperes, biots, abamperes, statamperes, and coulombs per second are all units of electric current.

## What is the conversion of frequency to current?

The pulse or frequency outputs from the various sensors and transmitters used to determine speed and flow are frequently transformed into a current or voltage signal to interface with a control system.

The required speed or flow signal is converted by frequency to current converters or frequency to mA converters into a corresponding current signal, typically 4-20 mA. Galvanic isolation is frequently used in these devices to reduce signal noise, and transients are often present in rotating machinery and heavy motor applications. More advanced solutions typically offer additional device capability to satisfy the interface needs of increasingly sophisticated applications.

A selection of frequency to current converters from PR Electronics are available with relay or NPN/PNP outputs in addition to or simultaneously with the analogue outputs. To address the interface issues of existing and upcoming applications, pulse division and multiplication options are now offered.

## What is a conversion from frequency to voltage?

The signal is converted to a corresponding voltage, typically 2-10 V depending on the interface requirements, via a process known as frequency to voltage conversion. The range of devices from PR Electronics is flexible enough to convert frequencies to voltage or current inside the same machine.

## What is the conversion of frequency to frequency?

For some applications, modifying a frequency signal to fit the needs of the downstream device is necessary. Gearing or response times may be to blame, in which case frequency division or buffering may be required. Using a frequency output as a frequency or time base generator is also possible.
