CR4420S-75

Current transducers are devices used to accurately measure and convert a current to an equivalent voltage signal. The CR4420S-75 is a commonly used current transducer from Techsource Sensor that is commonly used in industrial applications. It is designed to sense DC current up to 75A and output a corresponding voltage signal. This section will discuss the application field of the CR4420S-75 device, as well as its working principle.

Application Field

The CR4420S-75 current transducer is commonly used in industrial settings for the measurement of electrical currents. From gas and water industries to automotive, the device is capable of accurately and reliably detecting DC currents in those fields. The device also features a wide input range, from -75A to +75A, which allows for a large variety of applications. It can be used to monitor and control large motors, detecting and compensating thermoresistors, and monitoring current in hard to reach areas.

Working Principle

The CR4420S-75 current transducer works by using a Hall-effect sensor. This sensor consists of three main components: the sensing element which detects the current, the amplifier which amplifies the detected signal, and the output stage which is responsible for transforming the detected signal into a usable output. The Hall-effect sensor is activated by the magnetic field created by the current it is sensing, and then produces an output voltage signal proportional to the detected current. The amplifier amplifies this output voltage signal and sends it to the output stage, where the signal is converted into a usable voltage output.

The device also features a small built-in voltage regulator and an LED indicator for status monitoring. The voltage regulator ensures that the output voltage is within the specified range regardless of any external electrical noise. The LED indicator is used to indicate the status of the device, so that the user knows if it is running correctly or not. Additionally, the device is also designed to provide accurate and reliable readings in temperatures ranging from -40°C to +85°C.

Conclusion

The CR4420S-75 current transducer from Techsource Sensor is a widely used and reliable current measuring device in industrial settings. It uses a Hall-effect sensor and its own internal voltage regulator to provide accurate readings in a wide temperature range. With its wide input range, it can be used in many applications, from monitoring large motors to detecting and compensating thermoresistors. The device also features a LED indicator for easy status monitoring. All of these features make the CR4420S-75 an ideal device for accurate current measurements in industrial settings.
