The advanced air-purge technology provides the ultimate,
excellent anti-environmental performance.

This air-purge system dramatically increases the resistance to environment by supplying air to the sensor body to raise the inner pressure and preventing foreign objects from invading from outside. It exhibits strong performance in severe environments where liquids such as permeable oil, coolant liquids and cutting fluids spill over the detector.
