LMK 858 Hydrostatic Level Transmitter

The Hydrostatic Level Sensor | Transmitter LMK 858 has been developed for continuous level measurement in aggressive media. Usage in more viscous media, for example sludge, is possible because of the semi-flush diaphragm. The basic element is a mechanically robust and highly overloaded capacitive ceramic sensor; the transmitters are among others suited for the measurement of low filling heights with good long term stability. In order to facilitate stock-keeping and maintenance the transmitter head is plugged to the cable assembly with a connector and can be changed easily.

Features of the LMK 858 include:

  • Diameter 45 mm
  • Transmitter head and cable assembly plugged
  • Nominal pressure ranges: 0 to 40 cmWC up to 0 to 100 mWC (0 to 40 mbar up to 0 to 10 bar)
  • Output 4 – 20mA or Volts
  • Sensor technology: thick film/ceramic, capacitive
  • Accuracy: <±0.175%
  • Good long term stability
  • Cable protection with PVC pipe possible
  • Customer specific versions available

General Applications:

  • Level monitoring in open tanks with low filling heights
  • Depth or level measurement in wells and open waters
  • Ground water level measurement
  • Sewage treatment, water supply
  • Chemical and pharmaceutical industries
