A monitoring system that continuously monitors torsional vibrations.

Geislinger Monitoring

If the safety limits are exceeded, an alarm is triggered. The Geislinger Monitoring System (GMS) can also be used for measuring vibrations, oil pressure, oil temperature, detecting misfiring and for power monitoring. By detecting critical overloads, damage to the damper, coupling or other drive train components can be avoided.

The Geislinger Monitoring is usually used in conjunction with Geislinger Torsional Vibration Dampers and Torsional Elastic Couplings. Its main task is to monitor the components and recognize functional deviations.

The GMS Mark 5 provides additional features and can monitor multiple parameters simultaneously. The advanced user interface provides a fast and better insight into the condition of Geislinger products and thus helps to save costs.

It provides an easy-to-use USB interface for data acquisition. Intuitive operation by just pressing a single touch-button co-operates with the robust design and guarantees reliable operating, even under the roughest conditions.

Reliable sensors in combination with sturdy measuring gears precisely detect torsional vibrations in couplings, dampers, camshafts, and drive shafts. Customized algorithms filter and calculate static and dynamic twists between the elements as well as the vibratory angle. The calculated torsional vibration values are shown on the color display as figures, bar graphs, or as FFT analyzed values. If the operating limit is exceeded, an alarm is activated.

The system features internal data recording; from this valuable information, Geislinger specialists can evaluate if the damper or coupling is functioning correctly. The statement issued can be used as an official service document. It is recognized by classification societies and can also prevent the necessity of carrying out an overhaul.

applications

  • Misfiring (free-end) Monitoring: If a cylinder misfires, the alarm signal can be used as a warning to reduce the engine load or to disengage a clutch to avoid excessive vibration levels and further subsequent damage.
  • Damper Monitoring: Ensures trouble free operation of Geislinger Dampers.
  • Oil Pressure and Temperature Monitoring: Sensors inside the Geislinger oil supply are available as an option for 2 stroke applications.
  • Coupling Monitoring: Static and dynamic twists are calculated; both the power transmitted and the torque are displayed.
  • Multiple Product Monitoring: Multiple Geislinger products can be monitored on one or several engines.
  • Double-engine Monitoring: Two engines can be monitored simultaneously with only one system unit.
