5.1 Filter cover
For particularly rough operating conditions, the sensor protection can be improved
by using ifm accessories.
• The filter cover can be replaced with a cover cap with a tube fitting and a vent
tube that ends in a protected and dry area.
• The filter cover can be replaced with a closed cover cap.
When the closed cover cap is used, the measurement may deviate due to
fluctuations of the atmospheric pressure and pressure fluctuations inside
the unit (because there is no pressure compensation of the measuring cell
to the environment) (Δ 10 K ≤ 30 mbar).
