Yokogawa ALE111-S51 Level Transmitter | Capacitance, 4-20mA, General Purpose

Yokogawa ALE111-S51 Level Transmitter | Capacitance, 4-20mA, General Purpose

Yokogawa ALE111-S51 level transmitter specifications. Capacitance type, 4-20mA output, general purpose, for liquids/solids.

Product Overview

The Yokogawa ALE111-S51 is a capacitance-type level transmitter designed for continuous level measurement of liquids, slurries, and granular solids in bins, tanks, or silos. It operates by detecting changes in capacitance between an insulated probe and the vessel wall. It provides a standard 4-20mA output signal proportional to the measured level and is built for general-purpose industrial applications.

Important Notes

1. Performance depends on the dielectric constant (DK) of the measured material; low DK materials may require special probes

2. Probe must be selected based on media properties, vessel geometry, and process conditions

3. Coating or buildup on the probe can affect measurement accuracy

4. Not suitable for highly conductive or adhesive materials without special probe design

5. Calibration is required for the specific vessel and material
