Leaders in

With more than 50 years´experience Geislinger is one of the leading experts in providing solutions to control torsional vibrations. Every Geislinger product is tailor-made and thus perfectly suited to the application it is designed for.


The Geislinger Monitoring system GMS is a torsional vibration measurement and monitoring system for large diesel engines.

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


Reliable sensors in combination with sturdy measuring gears detect torsional vibrations precisely 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 colour 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 carrying out an overhaul.

    • 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.
    • Axial Vibration Monitoring: This option, available for 2-stroke applications only, reduces the number of monitoring systems, minimizing additional costs.
    • Coupling Monitoring: Static and dynamic twists are calculated; both the power transmitted and torque are displayed.
    • Power Monitoring: Engine output and shaft line vibrations are displayed to optimize fuel consumption and increase the propulsion safety level.
    • Multiple Product Monitoring: Multiple Geislinger products can be monitored on one or several engines. Double-engine Monitoring: Two engines can bemonitored simultaneously with only one system unit.
    • Self-monitoring system unit with a malfunction alarm
    • IP54 (display unit, front only) and IP67 (junction box)
    • 6 digital inputs and 4 analogue inputs
    • USB 2.0 for data acquisition and programming
    • Ethernet connection(1 GB/s) for ship network integration
    • Modbus and CAN interfaces for integration into AMS
    • 4 potential-free relay switches for alarm output
    • Analogue Output (4 – 20 mA)
    • TFT colour display, touch-button operation
    • ISO-fitting dimensions 192 x 147 mm
