The Current Sensor 2 Amp, designated as WBI342U01-S, converts DC input current into load-independent output signals of DC 0–5V or 0–10V. By employing the electromagnetic isolation principle, this sensor performs real-time measurement of DC current from electrical networks or circuits.
Benefits:
* Provides complete galvanic isolation between input and output.
* Ensures high measurement accuracy.
* Exhibits minimal drift caused by temperature variations.
* Operates efficiently over a wide temperature range.
Primary Accuracy Test Procedure:
1. Use an output monitoring meter, denoted as V1, to measure the output of the signal power source instrument. Select any input value within the transducer's measurement range, denoted as Ir (for example, an input value of 5A corresponding to an output range of 0–5V).
Calculate the expected output value, Uz, using the formula:
Uz = 5V × Ir / 5A
2. Use another output monitoring meter, designated as V2, to measure the output voltage Uo produced by the transducer.
Calculate the basic introduced error, γ, of the transducer using the following equation:
γ = (Uo − Uz) / 5V × 100
The accuracy of the Current Sensor can be verified through this straightforward testing procedure. By using output monitoring meters, the sensor's output can be compared with calculated values based on the input current. Any deviation can then be used to calculate the introduced error, providing insight into the sensor's performance and accuracy.
Whether used in industrial processes, energy management, or control systems, the Current Sensor 2 Amp – WBI342U01-S provides a reliable solution for precise current measurement, helping ensure the accuracy and stability of monitoring and control operations.
