Current transducers are increasingly utilized in industrial, commercial, and domestic applications. The CR4220S-100 is one such model of current transducer. This guide will cover the relevant application field and the working principle of the CR4220S-100.

Application Field

The CR4220S-100 is a special type of current transducer, designed to be used with low voltage - up to 100VAC. It mainly functions as an integrated monitoring device, featuring display of both current and voltage values in digital format. Additionally, the model further provides adjustable "critical peak" threshold adjustments and selectable alarm output via a digital interface. The CR4220S-100 is suitable for applications which require monitoring and reporting of specified current and/or voltage levels.

This transducer can be used in a wide range of settings, from commercial to domestic; from industrial to medical. Additionally, it is able to work with many instruments and systems, that have to do with voltage and current measurements. Examples include: medical equipment for monitoring blood pressure; high-voltage electric equipment; energy-efficiency system installations; home security systems; and more. Different settings take advantage of various features of the CR4220S-100, from displaying real-time readings, to displaying peak values.

Working Principle

The CR4220S-100 uses an electrical-optical system to convert an electrical signal to a digital output. This type of current transducer includes a current sensor (usually an integrated circuit (IC) based on Hall effect technology), LED light source, optical modulator, encoder/decoder and interface. The core of the transducer is the current sensor, which measures the electrical current with a specific current to voltage ratio. Using current to voltage conversion, the signal is converted to an equivalent voltage signal, which is then used to control the LED device embedded in the opto-electronic device. As the LED is triggered, light from the LED is modulated onto a specific optical pattern based on the input voltage. This combined light from the LED and optical modulator is then divided into two separate optical patterns, one for powering the device and the other for storing the measurements. The output is then decoded back into a digital format and passed onto the interface.

The main features that make the CR4220S-100 stand out are its precision and versatility. Its opto-electric system ensures that the measurements are accurate and reliable. Additionally, it is designed to be compatible with multiple types and models of instruments and systems. The model combines a wide range of features into one convenient device.

In summary, the CR4220S-100 is a versatile current transducer that is capable of delivering reliable, accurate, and easy-to-grasp readings. It is suitable for various settings and is able to work with various instruments and systems. With its opto-electric system, it is designed to be a reliable and precise monitoring device.
