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 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. 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. 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. fittings, measurement devices, valve boxes
