TC Fluid Control Reed-chain Level Sensor

TC Fluid Control Reed-chain Level Sensor

The model FLR sensors with reed-chain technology are used for level measurement in liquid media. They work on the float principle with magnetic transmission.

The float's magnetic system in the guide tube actuates a resistance measuring chain that corresponds to a 3-wire potentiometer circuit. The measurement voltage generated by this is proportional to the fill level.

The measurement voltage is very finely-stepped due to the contact separation of the measuring chain and is thus virtually continuous. Resolutions between 5 and 18 mm are available depending on the requirements.

Features

Features

  • Process- and system-specific solutions possible
  • Operating limits:
    - Operating temperature: T = -80 ... +200 °C
    - Operating pressure: P = Vacuum to 80 bar
    - Limit density: ρ ≥ 400 kg/m3

  • Process connection, guide tube and float from stainless steel 1.4571 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, 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 necessary
  • Level displayed proportional to volume or height
  • High repeatability
  • Interface measurement and overall level from ∆ density 50 kg/m³
  • Level sensors with reed-chain technology qualify as passive electrical equipment in accordance with DIN IEC 60079-11 and can be installed in “zone 1” hazardous areas without certification, so long as the equipment is operated in a certified intrinsically safe circuit with a minimum explosion protection of EEx ib.
