Endress+Hauser FEI50H 52028260 Liquid Level Sensor

The Endress+Hauser FEI50H 52028260 (FW-V 01.03.02, HW-V 02.01) is a capacitive electronic insert that works with the Liquicap M FMI51/FMI52 series to measure the level of liquid in industrial tanks all the time. This HART-enabled 4-20 mA transmitter works best with conductive liquids (≥100 µS/cm) and has immunity to buildup and interface detection for reliable automation control.

It can handle process pressures up to 100 bar and temperatures from -80°C to 200°C, making it perfect for chemical, food, and marine uses.

Key Features of Endress+Hauser FEI50H Liquid Level Sensor

-> The FEI50H has HART protocol for digital communication, which lets FieldCare software do remote diagnostics and configuration.

-> Its design doesn’t depend on the probe, so it works well with different dielectric constants, emulsions, and foams.

-> Small electronics that are easy to calibrate when wet for adjusting empty and full tanks.

-> ATEX/IECEx approvals for dangerous places (II 1/2 G Ex ia IIC T6).

-> Output that is resistant to noise (Ueff <2.2 mV) for stable signals in noisy places.

Technical Specifications of FEI50H Endress

Part number 52028260 specifies the FEI50H insert with firmware 01.03.02 and hardware 02.01, compatible with rod or rope probes up to 4m length. Power supply ranges 12-36 VDC, with span calibration from 25-4000 pF.​

Benefits:

• With the function switch, you can set the wet calibration to 4 mA (empty) and 20 mA (full), which cuts down on downtime.
• ART simulation helps with proof-testing, which increases safety in SIL applications.
• Its strong construction cuts down on maintenance and supports predictive analytics for process improvement.

Application in Industry:

• Put the FEI50H Liquicap M in storage tanks, reactors, and separators to keep them from overflowing, protect them from running dry, and keep track of your inventory.
• It does well in thick, sticky, or coating media without needing to be recalibrated.
• It keeps an eye on fuel, ballast, and chemical levels in marine and automation setups like ndmarinetech.com inventories.
