CS Instruments Residual Oil Content Measurement OILCHECK According To ISO 8573 - Stationary Solution

The residual oil content sensor OIL check measures the vaporous residual oil content in the compressed air. By means of a sample taking a representative part volume flow is taken from the compressed air and led to the OIL check.

Description

The residual oil content sensor OIL check measures the vaporous residual oil content in the compressed air. By means of a sample taking a representative part volume flow is taken from the compressed air and led to the OIL check. Due to the continuous measurement threshold value exceeding will be recognized immediately and remedial actions can be initiated to ensure oil-free compressed air.

CS Instruments

CS Instruments GmbH & Co. KG with locations in 24955 Harrislee and 78052 Villingen-Schwenningen/ Tannheim, is managed by Dipl. Eng. (FH) Wolfgang Blessing as sole Managing Director.

CS Instruments GmbH was established in the year 2002 by Christian Schuldt and Wolfgang Blessing as equal shareholders/Managing Directors.

Wolfgang Blessing already was sound a specialist on the sector of compressed air technology resp. industrial measurement technology long before the establishment of CS Instruments GmbH in the year 2002. Prior to the foundation of CS Instruments GmbH Dipl. Ing. (FH) Wolfgang Blessing acted for more than 10 years as primarily responsible product manager for industrial measurement technology at a worldwide known manufacturer of measuring instruments for compressed air and gases in the Black Forest. The technical knowledge and experience matched with the long-term practical knowledge was the corner stone for the success of CS Instruments.

Features

  • Permanent, highly precise residual oil measurement (oil
    vapour) with PID sensor (photo-ionic-detector)
  • Ideal for mobile measurement: The PID sensor is ready for
    measurement within about 30 minutes
  • Measuring results with long-term stability due to automatic
    zero point calibration. The integrated mini catalyst reliably
    generates a defi ned reference gas for zero point calibration
  • In contrast to measuring systems which generate the “zero
    air” or reference gas by means of active carbon fi lters and
    which are therefore dependent on the ageing and saturation
    of the active carbon fi lters, the mini catalyst generates the
    “zero air” without ageing or wear. There is no change of
    active carbon fi lters necessary
  • Easy sampling via PTFE hose or stainless steel pipe

Applications

  • Measuring compressed air quality
