Endress+Hauser FMB50 Static Pressure Level Transmitter

1. General Description

The Endress+Hauser FMB50 is a hydrostatic level sensor. Also called the Endress Hauser FMB50, Endress+Hauser FMB50 level transmitter, and Deltapilot FMB50.

This sensor measures hydrostatic pressure in liquids and thick media. This device measures levels well. It uses a hydrostatic pressure sensor to give stable and accurate readings in tanks, vessels, and process systems.

The Endress Hauser Deltapilot M FMB50-F9J6/0 Hydrostatic Sensor and Endress+Hauser Deltapilot FMB50-AA21SA1MGEUPJB3U Hydrostatic Pressure Sensor represent common configurations of this series. Users typically employ these transmitters in process and hygienic applications, supporting hydrostatic level measurement with pressure sensors for reliable, maintenance-friendly operation.

Engineers design the Endress Hauser level transmitter FMB50 with hermetically sealed, corrosion-resistant materials and robust process connections. As a level probe from Endress+Hauser's Deltapilot family, it provides reliable liquid level and fill level sensing. It offers great stability, durability, and easy installation.
