Current Transducers – HLSR 20-P/SP33

Current transducers are devices that input an electrical current from an AC/DC network, measure the electric current, and convert readings to an analog or digital signal. The HLSR 20-P/SP33 is a current transducer manufactured by Sensomag. It is a precision current transducer designed to measure AC and DC currents up to 100 A as well as pulsating alternating currents with frequency components up to 100 kHz. The HLSR 20-P/SP33 also offers a high sensitivity and a high degree of accuracy for current measurements.

Application Field

The HLSR 20-P/SP33 is designed for use in a variety of applications, such as measuring the electric current on motorized systems, transformers, generators, and other electrical devices. It can also be used to monitor the power consumption of large industrial plants and provide power factor correction. The sensor is also used in the electric vehicle charging industry to monitor successfully the charging and discharging currents of electrical vehicles. It is also used in research and development as well as classrooms and laboratories.

Working Principle

The HLSR 20-P/SP33 works by measuring current using a Rogowski coil which is mounted around the current carrying conductor. The electrical current flowing through the conductor generates a magnetic field in the coil, which induces an electric voltage. This voltage is measured and converted into an analog signal with a signal conditioner. The analog signal is sent to a device, such as a PLC or a data logger, which can analyze the signal.

The transducer has a wide range of input currents which makes it suitable for a variety of applications. It also has a high resolution, which allows it to measure very small currents. In addition, the operating temperature range is very wide, allowing it to be used in both cold and hot environments. This makes it suitable for use in a range of different industries. The HLSR 20-P/SP33 is also very compact, which makes it easy to install and transport.

The sensor uses a solid-state design so that it can be used outdoors even in harsh conditions. It is constructed with UL and CE certified components and is CE marked, which ensures that it meets the European safety standards. It is reliable and resistant to both short and long-term overloads which makes it ideal for high-current applications. The device also features an integrated lightning protection circuit for additional safety.

Conclusion

The HLSR 20-P/SP33 is a precision current transducer designed for use in a variety of applications, including motorized systems, transformers, generators, and other electrical devices. It features a wide range of input currents, a high resolution, a wide operating temperature range, and a compact design. It also features UL and CE certified components and an integrated lightning protection circuit for added safety. All of these features make the HLSR 20-P/SP33 a reliable and robust current transducer.
