Current Transducers : L18P020S05 Application Field and Working Principle

Current transducers, ranging from simple, off-the-shelf commercial solutions to complex, precisely calibrated laboratory instruments, are essential devices found in almost any industrial facility. In particular, the L18P020S05 current transducer, manufactured by Gefran, is a popular choice for precise, reliable current measurements in small to large amplitude applications. This article will discuss the application field and working principle of the Gefran L18P020S05 current transducer.

The L18P020S05 is available in either 4 ma or 20 ma input ranges and has a maximum operating current of 7 amps. It can be used in a wide variety of applications, including motor control, HVAC systems, automotive electronics, home appliances, industrial process monitoring, and lighting applications. This makes it ideal for any situation in which accurate, repeatable and reliable current measurements are required.

The L18P020S05 is a linear current transducer which works by sensing the level of current passing through the sensing circuit and converting it into an output voltage. The conversion takes place through a voltage is generated through the Hall effect. The Hall effect is a phenomenon where a voltage is generated by a current flowing through a sensor when placed in a magnetic field perpendicular to the direction of the current flow. This voltage is then proportional to the strength of the current flow.

The L18P020S05 has a variable linearity range of 0.5-1%. This means that the output voltage will be most accurate between 0.5% and 1% of the input range (e.g., 4ma or 20mA). Beyond this range, the output voltage will become less accurate with larger amplitudes. In addition, the output voltage is only valid if the sensing current is in the specified range – if the current is outside of the specified range, the output voltage will be clipped and not represent an accurate measurement.

The L18P020S05 also has a high frequency response range of 25 kHz to 250 kHz, meaning that it can accurately measure signals with frequencies up to 250 kHz. Additionally, it has a low-drift error of 0.05%/degrees Celsius, meaning that its output will remain consistent and stable over varying temperatures. These two features make the L18P020S05 especially suitable for applications where fast, precise and repeatable current measurements are required over varying conditions.

In summary, the Gefran L18P020S05 current transducer is a popular choice for applications requiring precise, repeatable and reliable current measurements over a wide range of operating conditions. It is available in either 4mA or 20mA input ranges and offers a variable linearity range of 0.5-1%, as well as a high frequency response of 25 kHz to 250 kHz. Additionally, it has a low drift error of 0.05%/degrees Celsius. All of these features make the L18P020S05 an ideal choice for industrial applications in which accurate and reliable current measurements are required.
