E3 Modulevel? Level Transmitter

Product Description:

The Digital E3Modulevel? is an advanced intrinsically safe two-wire instrument that utilizes the simple principle of buoyancy to detect liquid level changes and convert them into a stable output signal. The connecting piece between the level sensing element and the output electronics provides a simple mechanical design and structure. The vertical installation design of the transmitter allows the instrument···

Working Principle:

(1) The change in buoyancy caused by the liquid level variation acts on a spring-supported displacer, causing the core within the Linear Variable Differential Transformer (LVDT) to move vertically.

(2) As the position of the core changes with the liquid level, an induced voltage is generated in the secondary coil of the LVDT. This voltage signal is processed by the circuit and converted into a 4-20 mA current signal output. The sealed tube acts as an isolation barrier between the LVDT and the process medium.
