Instrumentation designed to measure crankshaft distortion and signal preventative action

Designed to work with WebMap2 software, the WDS measures crankshaft distortion due to bearing misalignment and enables corrective action prior to shaft or bearing failure. It is portable and easy to use, making for an accurate and reliable method to monitor and analyze trends in crankshaft web deflection measurements.

Crankshaft Operation

The Web Deflection System (WDS) is composed of a Display Unit, Deflection Measuring Head with extensions and adjusting hardware, Angle Measuring Head, connecting cables, and carrying case. A small transducer located within the Deflection Measuring Head measures minute deflections occurring within the webs of the crankshaft. Indicators on the Deflection Measuring Head assist with the proper installation between the throws or webs of the crankshaft. The Angle Measuring Head attaches to the crankshaft, to provide the angle reference for each measurement. The Display Unit provides remote indication of both deflection and angle of rotation. Separate buttons zero the deflection reading and preset the angular position. The display will also change color whenever the deflection exceeds selected limits.

Common Applications

  • Diesel engines
  • Gas engine compressors and reciprocating pumps
  • Marine propulsion engines and locomotives
  • Electrically driven gas compressors
  • Water and sewage pumping engines
  • Chemical plants
  • Pipeline compressor stations
  • Oil fields
  • Gas gathering networks
  • Aboard ships and on offshore platforms

WebMap2 Software Compatible

Combined with WebMap2 software, the WDS allows the user to automate data collection and more perform analysis easily. The WDS can then monitor and analyze trends in crankshaft web deflection as part of a comprehensive maintenance program. The WDS provides a steady stream of data, which is monitored by the PC and captured every 10 degrees of rotation. Data can be stored and reviewed for later use.
