We would like to introduce you to our very-popular ProBalance system. It is a low-cost, quick and easy to install continuous power cylinder pressure monitoring system. On a typical 12 cylinder engine, ProBalance can reduce balancing time from 1 to 1 ½ hours to 5-10 minutes, along with providing your Operations Team 24/7 alerts when the engine needs attention with alarms for out of balance conditions, detonation, misfires and erratic combustion.

To balance an engine, the operator simply carries the Snapshot Tablet (hand-held) with him on the engine. The Snapshot tablet displays live, continuous balance information for the engine. While making adjustments of the fuel flow for an out-of-balance cylinder, the operator can immediately see the results of the adjustment across the entire engine.

ProBalance BCM

The Balance Control Module (BCM) is a 12” x 10” x 6” enclosure that can be mounted at the UCP. The BCM has a 7” touchscreen that displays engine balance live. The BCM local display shows the engine’s balance plot indicating each cylinder’s deviation from engine average.



ProBalance ECM

The Engine Cylinder Modules (ECMs) are magnetically mounted and connected with a single, armored cable (one for each engine side for “V” configurations). Other than the 24 VDC to be supplied by the customer along with the dual port Kiene valves and pressure sensors (if not already installed), installation of the Machinery Monitoring Systems ProBalance system can typically be done within a day.

When is an engine considered balanced? 

The widely accepted technique for measuring engine balance is to compare each individual cylinder’s average peak firing pressure (PFP) against the entire engine’s average peak firing pressure. The individual cylinder pressure difference from the average is divided by the engine average. The resulting number is that cylinder’s balance percent. Most companies agree that a 5% balance is a good target for an engine in good mechanical condition and torque loaded to at least 90%. ProBalance provides continuous engine balancing data giving you the option to respond quickly to a need for balancing adjustments. In addition the system monitors and can alert the operators for misfires and detonations.
