Current transducers are components designed to measure and monitor the amount of current in an electrical circuit. CR4150-25 is a current transducer that can be used to measure and monitor both the amount of current in an electrical circuit and the transformer core temperatures. It consists of a core temperature sensor, a current transformer and a signal output transformer.

The core temperature sensor enables the CR4150-25 to be used in applications with high temperature requirements. The current transformer detects the relative differences in frequency in the electrical signal and transmits this signal to the output transformer. The signal output transformer steps the AC electrical signal down, enabling the readings to be displayed on a digital display or transmitted to a computer system.

The CR4150-25 is specifically designed for applications where real-time current measurements are needed. Examples of this may include industrial machinery that requires continuous monitoring, power electronics in test laboratories or medical equipment. The performance of the CR4150-25 is optimized for measuring currents from 0.1A to 25A with 0.01% accuracy.

The working principle of the CR4150-25 is based on the Faraday’s law of induction. The amount of current passing through a conductor generates a magnetic field, which in turn induces an AC voltage in the transformer. To measure the current, the voltage output from the transformer is compared to a reference value. This reference can either be pre-calibrated or take as a percentage of the input current.

In order to work correctly, the CR4150-25 also needs to be correctly connected to the transformer, with the conductor carrying the current being connected to the primary winding. The secondary winding should be terminated in a low-impedance load in order to maintain the correct signal-to-noise ratio.

In addition to measuring the current, the CR4150-25 can also be used for monitoring the temperature of the transformer core. When the temperature reaches a critical point, an alarm can be triggered to alert the user. This is useful in potentially hazardous scenarios, such as electrical faults or a build-up of heat.

The CR4150-25 is a robust, reliable and cost-effective current transducer that can be used to measure and monitor both the amount of current and the temperature of a transformer core. It is easy to install and can be used in a variety of industrial, laboratory and medical applications where real-time current measurements are required.
