Inductive slot sensors – small, low price and versatile.
 
 

 
 Precise position detection for instrumentation.
  • Standardised housing for easy installation.
  • Approvals to ATEX and IECEx.
  • Namur interface.
  • Wide temperature range.

Applications
Applications for slot sensors can be found on measuring devices or instruments for metering pressures and flow rates. The sensors can be installed individually and ensure wear-free and non-contact switching. The sensor target
can be made of different materials.

Typical applications:
In a meter the sensor detects slots in a disc. In a vane-type flow meter the pointer counterweight position is detected by slot sensors.

Versions
The new inductive slot sensors are approved for Category 1 ATEX gas and dust areas. The sensors can be operated outside ATEX areas with 24 V.

Applications:
fittings, measurement devices, valve boxes
