RT 500

Current Sensors Overview

The RT 500 is a current sensor manufactured by LEM USA Inc., designed for the measurement of alternating current (AC). It utilizes transformer technology to provide electrical isolation between the primary conductor and the secondary circuit. The device features a bidirectional output configuration, allowing it to accurately track both positive and negative current cycles. It operates within a temperature range of -10°C to 65°C and supports free-hanging installation methods. The sensor delivers a ratiometric voltage output proportional to the measured current.

Current Sensors Procurement Notes

Verify the specific datasheet version when sourcing this component, as manufacturer documentation may vary over time. Confirm that the application environment remains within the specified operating temperature limits of -10°C to 65°C. Ensure the power supply voltage matches the requirements for the ratiometric output stage. Check for any updated replacement recommendations from LEM USA Inc. prior to finalizing procurement decisions.

Current Sensors Selection Notes

Select the RT 500 specifically for applications requiring isolated AC current measurement with bidirectional output. This model is suitable where transformer-based sensing offers advantages over Hall effect sensors in terms of drift characteristics. Consider the free-hanging mounting style when designing the mechanical enclosure. Verify that the required bandwidth and accuracy meet the system specifications before choosing this part number.

Current Sensors Part Context

The RT 500 belongs to the broader category of current sensors produced by LEM USA Inc. It is distinct from the company's Hall effect series, such as the LF or HAC models, by utilizing transformer technology. This places it in a specific niche for AC measurements where low drift and high linearity are prioritized. It serves as an alternative to other transformer-based sensors in industrial automation and power electronics sectors.
