OTT SE 200

OTT SE 200 float-operated shaft encoder water level sensor

The OTT SE 200 float-operated shaft encoder level sensor provides proven water level measurements in continuous, unattended monitoring in ground and surface water applications. A measured value is being calculated via internal processing and is available via the interfaces SDI-12 and 4 ... 20 mA.
  • Surface water, Groundwater
  • Water level
  • Float-operated Shaft Encoder
  • Continuous water level measurement - for use with external data logger
  • ±30 m
  • No
  • SDI-12 or 4 ...20 mA
  • Easily mounts into a 4, 5 or 6-inch pipe with optional pipe mount kit
  • 4 ... 20 mA signal or serial data interface SDI-12 available
  • Improved resolution by allocation of 4 ... 20 mA signal to the actually required measuring range possible
  • Simple system integration with standard signal 4 ... 20 mA
  • Variable: can be supplied with float cable or beaded cable

For water level measurement of:

  • Streams, rivers, channels, or canals
  • Groundwater wells
