Current transducers are devices that convert current into a proportional electrical signal. They are used in a variety of applications for monitoring, control, and testing of electrical systems. The CR4420S-30 is a popular example of a current transducer used in the industrial environment. This article will discuss the application field and working principle of the CR4420S-30 current transducer.

The CR4420S-30 is an AC current transducer that is ideal for monitoring and controlling a range of electrical systems, including power distribution, control circuit protection, heating and cooling systems, lighting control systems, and even automotive systems. It can measure up to 30 Amps of current and has an accuracy of 0.2%. The transducer is also equipped with overload protection, and it has a rapid response time of less than 200 milliseconds.

In terms of its application field, the CR4420S-30 can be used in a variety of industrial and commercial settings. It is well-suited for use in automated manufacturing, power distribution, and any other applications where accurate current measurement is important. It is also suitable for use in hazardous environments, as it has a safety approved rating of Class II Division 1.

As far as its working principle is concerned, the CR4420S-30 works by converting the measured current into an electrical signal. This is done through a process known as magneto-striction. When the measured current is applied to the transducer, the internal magnets rotate and push against a set of coils. This causes the signal coil to vibrate, which in turn generates an electrical voltage proportional to the measured current. This voltage is then amplified and sent to an analog to digital converter, which then produces a digital output representing the magnitude and direction of the measured current.

The CR4420S-30 is a reliable and accurate current transducer that is well-suited for use in a variety of industrial and commercial applications. Its magneto-striction based working principle provides fast response times and excellent accuracy, and it is also equipped with overload protection for added safety. It is an essential tool for accurate and reliable current measurement in any application.
