If you want to know exactly what power your machine has, Hoppe offers a compact and precise power measurement system that meets all requirements for upcoming emission savings. It serves as the basis for fleet digitalization and performance monitoring.

your machine´s power

  • System with highest measuring accuracy (< 0.5% at all load levels)
  • Calculates averages per hour, per day, and for a user-defined period
  • Generates „heavy run alarm“ or „torque alarm“ with respect to the customer‘s settings
  • Calibrated sensors with self-validation by software in operation
  • Maintenance free and easy calibration by crew
  • For solid and hollow shaft sizes > 150 mm ø and speed up to 800 rpm

MEASURING PRINCIPLE

  • Based on two acoustic vibrating wire sensors
  • The sensors operate with a natural frequency of 600 Hz
  • Due to their orientation, one sensor is stretched and the other is compressed when the shaft is twisted by torque
  • In addition, the shaft rotation is measured with a gyroscope, an accelerometer and a Hall sensor
  • The product of the mechanical torsion and the shaft speed is the shaft power
  • The system is delivered fully calibrated from the factory
