The Digital ES II and Analog EZ Modulevels are advanced, intrinsically safe two-wire or four-wire instruments utilizing simple buoyancy principle to detect and convert liquid level changes into a stable 4–20 mA output signal. The linkage between the level sensing element and output electronics provides a sim-ple mechanical design and construction. The vertical in-line design of the transmitter results in low instru-ment weight and simplified installation. The instrument comes in a variety of configurations and pressure ratings for varied applications.
The Digital ES II Modulevel has microprocessor-based electronics with HART compatible output, in addition to the standard 4–20 mA output, while the Analog EZ Modulevel provides a simple 4–20 mA output signal.

Changing buoyancy forces caused by liquid level change acting upon the spring supported displacer cause vertical motion of a core within a linear variable differential transformer.
As the core position changes with liquid level, voltages | ||||
are induced across the secondary windings of the | ||||
LVDT. These signals are processed in the electronic | ||||
circuitry and used to control the | current | in | the | |
4–20 mA current loop. The enclosing tube acts as a | ||||
static isolation barrier between the | LVDT | and | the | A P P L I C A T I O N S |
process media. | |||||
