The ExaktGroup is an unique platform on which technical specialists cooperate. The aim of the Group is to deliver a seamless scope of Products and Services for the installation, maintenance and repair of rotating machinery. The Group is formed by companies performing services in the field of Alignment, In-Situ Machining and Propulsion&Hydraulics.
Vibration measurement; linear vibration, impact/mobility tests, modal analyses and Operational Deflection Shape (ODS).
Rotational vibration measurement with speed pick-up (gear or flywheel) or shaft encoder.
Noise; airborne and structure borne noise (ABN and SBN).
Torque / power measurement on rotating shafts via strain gauge sensor and telemetry transition.
On-site balancing of rotating equipmen
Performing measurements of dynamic parameters like pressures, stresses, temperatures, vibrations etc.
Instrumentation of (engine) parts with custom made sensors like fuel injectors needle lift, cylinder heads with pressure and temperature sensors, stress or movements sensors in mechanical structures like thrusters housings etc.
Providing expertise in instrumentation, sensor selection, calibration, measurement possibilities.
Give independent evaluation of data with recommendation.
Time based dynamic measurements. Signals like pressures, temperatures, strain/stress and/or voltages recorded in time domain.
Crank angle based dynamic measurements of pressures (combustion, fuel, injection, rail, etc.) injector needle lift, strain/stress, voltages.
Engine performance measurement; multiple signals of engine/turbo performance indicators.
Flow measurement (water/oil) with ultrasonic clamp-on meter and fuel consumption measurements with Coriolis mass flow meters.
