  • OIL SAMPLING OBJECTIVES

    Objectives to strategic sampling

    Maximize data density

    Minimize data disturbance

    Maintain proper frequency

    Strategic sampling considerations

    Sampling location

  • OIL SAMPLING PORTS

    Protective cap seals against dirt and moisture

    Cap connected to sample port with heavy brass chain to prevent loss

    Sample directly from lubricating oil while equipment is running

    Minimizes introduction of contamination into system

    Used in conjunction with proper accessories sample ports are adaptable to pressure, static, and vacuum locations

  • PITOT TUBES

    Pitot tubes are used for non-pressurized applications

    Complete assembly consists of a test port and sampling tube

    Available in various lengths and thread configurations

    Liquid level gauge ports for fluid level visibility

  • VACUUM PUMP

    Plastic tubing should not be in

    contact with the oil

    A vacuum pump is used to

    extract sample. Care must be

    taken to ensure that the

    internals of the pump are not

    contaminated with oil, dirt,

    water, etc.

  • SAMPLING METHODS - STATIC

    Sample while equipment is running and at typical operating temperatures.

    For reservoir sampling a rod can be used with new tubing to achieve consistent sampling location. Cut tubing length such that sample is pulled approximately in the middle of the reservoir avoiding the walls and bottom of

    reservoir.

    Difficult to keep rod clean between each oil sample as oil will attract dirt.

    Acceptable Not Acceptable

  • STATIC OIL SAMPLING DROP TUBE

    Drop Tube

    Best Applications Tank and reservoir sampling

    Crankcase oils, if a live zone sampling port is not

    available

    Equipment where trending particle counts and

    moisture level are not important.

    Subject to Safety Issues not recommended when exposed

    to rotating components

    Can Introduce Contaminates into Sample and System

    Difficult in Consistency of oil sample location

    Effective for Chemical Analysis

    Better Options are Available

  • DRAIN PORT SAMPLING

    Most common method utilized

    Typically, only port available for pulling

    sample.

    Particulates & water settle to the
