E4 Modulevel® Liquid Level Displacer Transmitter
The E4 Modulevel® is a 4-20 mA float level transmitter designed for continuous level measurement of liquids and slurries in industrial processes. Thanks to LVDT technology, the device provides stable and accurate measurements even in the presence of turbulence, foam and boiling. It also supports interface measurement and density control.
About product
The E4 Modulevel® is a two-wire, loop-powered measuring device that uses the simple buoyancy principle to detect changes in liquid level and convert them into a stable output signal. The mechanical connection between the level sensing element and the output electronics ensures a simple and robust design. The vertical linear design of the transducer reduces its weight and simplifies installation. The device is available in various configurations and pressure versions for a wide range of applications.
Principle of operation
The buoyancy force changes caused by fluctuations in the liquid level act on a float suspended by a spring, causing the core in the linear differential transformer (LVDT) to move vertically.
As the core changes position in accordance with the liquid level, voltages are induced in the secondary windings of the LVDT. The resulting signals are processed by electronic circuitry and used to control the current in the 4-20 mA loop. The protective tube acts as a static isolation barrier between the LVDT and the process medium.
