A. Product Overview
The RDCL RDCLFS1000 Magnetoresistive Float Level Transmitter continuously measures liquid levels using a magnetic float and magnetoresistive sensing technology. As the liquid rises or falls, the float moves along the probe. Internal sensing elements detect the changing magnetic field and convert the float position into a proportional electrical signal.
The float does not contact the internal electronics. A 4 to 20 mA output connects to compatible PLCs, indicators and monitoring systems.
Material choices include stainless steel 304, stainless steel 316, F4 and polypropylene for compatible water, chemical and storage applications.

B. Working Principle
The RDCLFS1000 uses the magnetoresistive effect: sensing element resistance changes with the magnetic field of a permanent magnet inside the float. Electronics detect its movement and calculate liquid level.
Step-by-Step Working Process
Magnetic Float Movement: A buoyant float containing a permanent magnet moves vertically along the sensing probe as liquid rises or falls.
Magnetic Field Detection: The magnet's position changes relative to magnetoresistive sensing elements inside the probe.
Resistance Variation: The sensing elements respond to the changing magnetic field through variations in electrical resistance.
Signal Processing: Internal electronics interpret these resistance changes to determine the float position and corresponding liquid level.
Analog Signal Conversion: The calculated level is converted into a standard 4 to 20 mA signal representing the configured measurement range.
Continuous Level Monitoring: The signal can be transmitted to a compatible PLC, indicator, data acquisition system or industrial monitoring equipment.
This provides continuous measurement without direct contact between the float and sensing electronics.
C. Why Is the RDCLFS1000 Magnetoresistive Float Level Transmitter Used?
The RDCLFS1000 provides continuous level readings in industrial tanks, storage vessels and automated processes.
Key Benefits
Continuous Liquid Level Measurement: Monitors liquid level changes throughout the configured span, rather than only indicating high or low levels.
High Measurement Sensitivity: Magnetoresistive sensors detect changes in magnetic float position to support accurate measurement.
Standard Industrial Output: A 4 to 20 mA signal connects to compatible PLC analog inputs, controllers, process indicators and monitoring systems.
Wide Measuring Range: Options from 0.3 to 6 meters serve different tank sizes and industrial liquid storage requirements.
Stable Performance: The sensing design is intended to provide stable level readings and resistance to electromagnetic interference in industrial environments.
Multiple Material Options: Stainless steel 304, stainless steel 316, F4 and polypropylene offer choices for different liquids, subject to chemical compatibility.
Response to Level Changes: Float movement is detected electronically as the liquid level rises or falls.
Industrial Protection: The IP65 enclosure rating provides protection against dust ingress and water jets under specified conditions.
Low Power Consumption: Magnetoresistive sensing elements generally require relatively little electrical power.
Automation Compatibility: Continuous level data can support pump control, tank inventory monitoring and alarms through an external controller.
