project description and objective
Project Description and Objective

The purpose of this project is to monitor the health of the main crank bearing on RIT’s Dresser-Rand ESH-1 compressor. This will be done through recording vibration measurements via wireless sensor technology.

previous work
Previous Work
  • Team 12453 installed a range of sensors on the compressor and expanded the capabilities of the data acquisition (DAQ) system

Pugh Chart for Mounting Sensor on Shaft
  • Drill and Tap is the chosen method
  • Glue and Wax are clearly inferior options
  • Welding is roughly on par
    • However, welding is not practical

  • Option 1: Commercial Off The Shelf
  • Option 2: Develop In-House with PCB Mounted Accelerometer
  • Option 3: Develop In-House with Commercial Accelerometer

Option 3 was chosen due to expert reccommedation

test rig
Test Rig
  • In order to validate the wireless signal transmission on the rotating shaft, a model test facility will be constructed
  • 1:1 scale for shaft diameter and rotational speed
  • Bearing configuration will not be identical to actual compressor for the sake of simplicity
