Description
Fischer NR56 – Level transmitter with magnetic reed, monitoring foam in fire engines etc
Accurate, liquid level switch with LED indicator, for conductive liquid, contaminated liquids
Make: Fischer Messtechnik (Germany)
Model: NR56
Fischer NR56 is especially designed level sensor transmitter with magnetic reed switch, for foam level monitoring in fire engines.
Working Principle:
Fischer tank level sensor NR56 consists of a foam sensor with probe road of 250 to 1400 mm length. A floating magnet moves freely on NR56 probe.
NR56 consists of probe head with screw-in thread for probe mounting, an integrated measurement amplifier and cable junction. Stainless steel and plastics are used as materials in contact with liquid. The output signal proportional to filling level height get transformed by measuring amplifier to standard electrical signal. EA01 or EA14F or other display monitor can be used to readout corresponding tank level.
