Application

Position monitoring for reservoir crest control.

Key Requirements

  • Non-contact sensor to monitor the position of reservoir floodgates
  • Highly accurate linear output to provide fine control of the reservoir water level
  • Compact housing that has immunity to adverse weather conditions
  • Broad range parameters to compensate for poor electrical supply within remote site installations
  • Standard industrial output signal that will interface with existing control systems

Solution

ASM PMIS3 POSIMAG magnetic scale position sensor with the following key features;

  • Magnetically coupled non-contact read head and coded tape provide for a wear free extended service life
  • Up to 5 micro-metre linear resolution over a distance of up to 50m, with a sensor to tape side tolerance of only +/- 1mm
  • 35mm x 25mm x 10mm, IP67 corrosion resistant die cast zinc housing that can operate in temperatures ranging between -40 to +85 degrees C
  • 10 to 30 VDC supply range with EMC protection in accordance with DIN EN 61326
  • Choice of incremental push-pull output or RS422 output to allow for connection to standard industrial control devices
