Current transducers, which are also known as current transformers, are used to derive an electrical signal from an electrical current. The SI8513-B-GM is a current transducer developed by Siemens which is specifically designed for measuring, monitoring and controlling currents. It is used to accurately measure low and high current values and display them as an analog signal.

The SI8513-B-GM is equipped with a galvanically isolated amplifier that allows it to measure the current without risk of short circuit or overload. The instrument requires an external power supply for operation, and it is typically supplied with either twin or single ended inputs, depending on the application. The SI8513-B-GM is available with a wide range of resolutions, from 0.1 to 10 mA/bit, and it is suitable for current measurements from 0.1 mA to 10 A. The instrument also features a low temporal resolution, meaning it can accurately measure fast changes of current.

The SI8513-B-GM has a wide range of application fields, such as in solar installations, windpower plants, hydroelectric power plants, and in industrial automation, motor drives, and power electronics. In these applications, the transducer can be used to monitor and control currents in the power conversion system, as well as to accurately measure instantaneous changes of current.

The working principle of the SI8513-B-GM is based on the Hall Effect. As current passes through the transformer, it creates a magnetic field which is detected by a Hall Effect magnetic field sensor. The output of the sensor is then amplified, converted into an analog signal, and sent to a controller. The controller can then be used to measure and control the current.

The SI8513-B-GM is a highly-accurate and reliable current transducer which provides a safe and efficient way to measure and monitor electrical current. Its wide range of applications and features make it an ideal solution for monitoring and controlling currents in industrial automation, motor drives, and power conversion systems. Furthermore, its low temporal resolution makes it suitable for accurately measuring rapid changes of current.
