TC Fluid Control Magnetostrictive Level Sensor

Description

TC Fluid Control Magnetostrictive sensors are used for the high-accuracy, continuous level measurement of liquids and are based on determining the position of a magnetic float according to the magnetostrictive measuring principle.

TC Fluid Control Magnetostrictive Applications

• High-accuracy level measurement for almost all liquid media
• Chemical industry, petrochemical industry, natural gas, offshore, shipbuilding, machine building, power generating equipment, power stations
• Process water and drinking water treatment, food and beverage industry, pharmaceutical industry

Features

• Process and system-specific solutions possible
• Operating limits: Operating temperature: T = -90 … +400 °C, Working pressure: P = Vacuum to 100 bar, Limit S. G.: ? ? 400 kg/m³
• Resolution < 0.1 mm
• Wide variety of different electrical connections, process connections and materials
• Explosion-protected versions
• Large scope of application due to the simple, proven functional principle
• Process connection, guide tube and float from stainless steel 1.4571, 1.4435, 1.4539 or plastic
• For harsh operating conditions, long service life
• Continuous measurement of levels, independent of physical and chemical changes of the media such as: Foaming, conductivity, dielectric constant, pressure, vacuum, temperature, vapours, condensation, bubble formation, boiling effects, density change
• Signal transmission over long distances
• Simple installation and commissioning, onetime calibration only, no recalibration
• Level displayed proportional to volume or height
• Parallel measurement of interface layer and overall level possible via HART® interface

TC Fluid Control Magnetostrictive Options

• Customised solutions
• Process connection, guide tube material and float from special steel, titanium, Hastelloy (others on request)
• In combination with limit switch, stepless setting of the limit values over the entire measuring range

Design and operating principle

• The measuring process is triggered by a current impulse. This current produces a circular magnetic field (3) along a wire (1) made of magnetostrictive material fixed in the guide
• At the point being measured (liquid level) there is a float with permanent magnets (4) acting as a position
• The interaction of both magnetic fields generates a mechanical torsion wave (5) in the
• This is converted into an electrical signal at the end of the wire in the sensor housing (2) by a piezoceramic converter.
• The measured propagation delay enables the origination point, and thus the float position, to be determined with high
