MNS2-9-W2-CM-020 Current Transducers: Application Field and Working Principle

A current transducer is a device that can measure current by converting it into an analog or digital signal. The MNS2-9-W2-CM-020 current transducer is one of the most efficient and cost-effective current transducers currently available on the market today. This current transducer is designed for low level current measurements from 1mA up to 2000A in both AC and DC input ranges. Its wide input range and small size make it ideal for a variety of applications, such as industrial and power system monitoring, data acquisition, instrumentation, and controlling.

The MNS2-9-W2-CM-020 is a linear and temperature compensated integrative Hall effect current transducer. It consists of a magnetic-type fluxgate sensing element, a signal conditioning processor, a linearized output amplifier, a galvanic isolation amplifier, and additional circuitry. It has a 90VAC/750V peak withstand voltage (note that the peak withstand voltage should be less than 1500Vrms for 2000A accuracy); a programmable output signal range of 0-20mA, 4-20mA, 0-1V, 0-5V, or 0-10V; an accuracy of +/- 0.5% of reading (measurements at 2000A); and a working temperature range of -40 to 85 degrees Celsius. In addition, it has a maximum frequency response of DC to 200KHz.

The working principle of the MNS2-9-W2-CM-020 current transducer is based on the magnetic fluxgate principle. It uses a precisely controlled magnetic field to measure current. The transducer has three coils: a primary winding, a secondary winding, and a fluxgate winding. The current passing through the primary winding generates a magnetic field in the fluxgate winding. This field is detected by the secondary winding which generates a current proportional to the field strength. This output signal is then processed by the transducer’s signal conditioning circuitry and linearized output amplifier.

The MNS2-9-W2-CM-020 current transducer is an ideal solution for industrial and power system monitoring, data acquisition, instrumentation, and controlling. With its linear and temperature compensated design, it offers a reliable, accurate, and cost-effective solution for current measurements from mA to kA ranges. Its wide input range and small size make it an ideal choice for a variety of applications.
