Digital ES and Analog EZ Modulevels are advanced, intrin-sically safe two-wire instruments, utilizing simple buoyancyprinciple to detect and convert liquid level changes into astable 4–20 mA output signal. The linkage between the levelsensing element and output electronics greatly simplifiesmechanical design and construction. The in-line verticaldesign of the transmitter reduces instrument weight andsimplifies installation.

The Digital ES Modulevel has microprocessor-based elec-tronics with HART compatible output, in addition to thestandard 4–20 mA DC output. The Analog EZ Modulevelprovides a 4–20 mA DC output only.

Digital ES Modulevel Features

Digital ES and Analog EZ Modulevel Features

Principle of operation

Liquid level change acts upon the spring supported displac-er causing vertical motion of a core within a linear variabledifferential transformer (LVDT).

The enclosing tube acts as a static isolation barrier betweenthe LVDT and the process media. As the core positionchanges with liquid level, voltages are induced in the sec-ondary windings of the LVDT. These signals are processedin the electronic circuitry and used to control the current inthe 4–20 mA output current loop.

Digital ES transmitters add the HART output in addition tothe analog 4–20 mA DC output.

These units have been tested to EN 50081-2 and EN 50082-2 andare in compliance with the EMC Directive 89/336/EEC.

➀ These performance characteristics appy to units measuring liquid level; interface measurement units may not exhibit the same perfor-mance.

➁ Minimum temperatures given are for carbon steel construction materials. Complete stainless steel is recommended for lower processtemperatures. Maximum temperatures given are based on ambient temperatures up to +120° F (+49° C) on models without cooling fins.Higher ambient temperatures require reduced process temperatures.
