The Condition Monitoring Pod (CMP)

The CMP is an all-in-one oil sight glass thanks to their multi-use functions. It has a 3D sight glass for checking the oil level, colour and clarity. It also includes a visible magnetic plug inside the glass to capture wear debris and make it easily visible. A built-in sampling valve with an attached pilot tube for live-zone oil sampling. The CMP is made of Tritan co-polyester.


It includes:

  • a 3D sight glass offering a 360-degree view (for checking colour and clarity, oil level and foaming, wear debris or corrosion),

  • a built-in oil sampling port (with attached pilot tube for live-zone oil sampling),

  • an easy-to-remove magnetic plug (to capture wear debris and make it easily visible),

  • a corrosion/ varnish inspection probe,

  • and quick lubricant access point for syringe sampling.


Early Fault Detection

Early detection of machine faults and abnormal wear is key machine reliability. The failure development period begins with ”P”, the point of first detection, and ends with “F”, the state of operational failure. The longer the PF interval the greater the likelihood a failure can be detected before expensive collateral damage and unscheduled downtime occurs. The CMP enables daily inspections across numerous critical parameters. This capability delivers a huge benefit over less frequent oil sampling and other condition monitoring activities (vibe, thermography, acoustics, etc.). 


Best applications include:

  • gearboxes,

  • bearing oil sumps,

  • hydraulic reservoirs,

  • compressor oil reservoirs,

  • turbine-generator

  • main oil tanks and

  • paper machine central reservoirs.


Comprehensive Inspection 

Most sight glass level gauges are used only to confirm oil volume. Many root causes and symptoms of machine failure are missed due to the limited ability of these sight glasses. The CMP is a multi-parameter inspection pod that greatly modernizes and expands daily one-minute inspections. 

The magnetic plug picks up any metal findings and wear debris.

CONDITION MONITORING POD (CMP) INSTALLATION

Filter cart OilSafe

A step-by-step installation guide for the Condition Monitoring Pod (CMP).


The Condition Monitoring Pod is a multi-parameter device for expanding daily lubricant inspections. The CMP is a visible inspection window providing a method of inspecting machine health without the need for laboratory analysis.  Below you'll find a detailed description on how to install a Condition Monitoring Pod (CMP).


Before beginning installation you will need to have the following material on hand:


  • a pipe bender for 3/16” or ¼” diameter pipe, 
  • a 2" and ¾” pipe wrench, 
  • PTFE thread sealing tape, 
  • oil rags
  • and whatever equipment your facility uses to remove oil from the machinery on which the CMP will be installed. In most cases a filter or transfer cart would be best.

  • Identify a porthole on the machine that has positioned at the oil level.
  • Do not install the Conditon Monitoring Pod (CMP) below the oil level or on pressurized systems. 
  • Drop the machines oil level below the porthole, using established best practice procedures for your facility. This will prevent spillage during the CMP installation. 
  • Tightly thread the reducer into the machine's porthole using a two and three quarter inch wrench and enough pipe thread sealing tape to prevent leakage, and thread the CMP into the reducer.

  • If the sampling port is not at a convenient location when fully tightened, use the supplied shims between the reducer and the CMP to reorient the sampling port. In this example the sampling port will be installed facing upward.  
  • With the CMP threaded onto the reducer and the sampling port properly oriented, note the downward direction for bending the pilot tube. Remove the CMP from the reducer being mindful of any shims that may have been used using the appropriate pipe bender.
  • Bend the pilot tube in the direction noted in the previous step.
  • Choose a bend location and angle that place the pilot tubes tip within the machine and below the oil level for proper sampling. Tightly thread the CMP into the reducer using shims and enough sealing tape to prevent leakage. Use the sampling port as leverage to achieve enough torque if necessary

  • Loosen the lock nut and rotate the sight glass so that the magnetic plug is at the bottom and the corrosion indicator rod is at the top can tighten the lock nut. 
  • Do not use sealing tape or thread locker on the lock nut. 
  • Replenish the machine with oil so that the oil is level with the crosshairs on the sight glass. 
  • Again using established best practice procedures for your facility

FAQ Condition Monitoring Pod (CMP)

What machine port hole diameters can be used with the CMP?

The CMP is currently designed for the following port sizes:

NPT : 0.5", 0.75", 1", 1.25", 1.5"
BSPP : 0.5", 0.75", 1"
Metric : 0.5" ((M20x1.5)

You may use additional bushings to expand the thread diameter but not to reduce it.
Reducing the diameter will cause errors in oil level measurement.

How does the CMP detect varnish?

The CMP comes with a Steel Corrosion Indicator (a Copper Corrosion Indicator is also available). If varnish is observed on the Corrosion Indicator through the Sight Glass, this is an indicator of a current or potential varnish problem. Varnish on the Corrosion Indicator = Varnish on the Inside of your Machine.

Is the CMP compatible with synthetic lubricants such as polyalphaolefins (PAO) and phosphate esters?

The materials used in the CMP are compatible with mineral oils and most synthetic lubricants (e.g., PAO). Certain synthetics, such as phosphate esters, may exhibit marginal incompatibility. When in doubt it is recommended that compatibility be confirmed by contacting the lubricant supplier or performing compatibility tests in the laboratory.

Will the CMP leak if the oil sump is overfilled causing the sight glass to be completely filled with oil?

In normal use the CMP will not leak if filled above the oil level, however it is not recommended that this be a standard practice. This is also dependent on the tightness of the CMP threads and use of thread sealer.

How far below the oil level should the tip of the pilot tube be located?

The Pilot Tube tip should never rise above the oil level during standard operating conditions. If this level is not known then it is best to bend the Pilot Tube as far down as possible without interfering with internal machine components or hindering installation.

Can the CMP be exposed to high pressure washing?

The CMP can be exposed to high pressure washing but it is not advised to spray the CMP directly with wash fluids at close range.

Can I install the CMP without lowering the oil level in my sump first?

Yes it is possible but not advised due to the amount of oil that might be lost and the associated hazard of leakage.

How often should I inspect oil conditions through the CMP?

We advise daily inspections of the CMP for early detection of problems with the oil and machine.

Won’t the threaded ports on the Sight Glass be potential contaminant entry points?

We estimate that at least ninety-five percent of the inspections of the magnet and corrosion indicators can be done without exposing the oil to the atmosphere (e.g., visually through the sight glass). The only time the magnet or indicator needs to be removed is when a real issue has been observed (as viewed through the sealed sight glass). If such an issue exists, either related to a problem with the oil (e.g., varnish or loss of corrosion suppression) or the machine (e.g., abnormal wear), we believe that early detection commands a far higher premium than a minor and temporary exposure of the oil to atmospheric contaminants.
