Vibration measurements - Import export

EWS takes measures against vibrations in deep drilling procedures Deep drilling procedures with drilling rods with a long overhang are one of the most demanding tasks in cutting technologies. What influences vibration, what amplitudes does it create, what is the effect of superimposed vibration and when are uncontrollable resonances encountered? All these are questions that are difficult to answer using theory alone. These findings formed the basis for the new development of EWS Rigid. The objective was to create a drilling holder with a passive damping system to counteract the vibrations that are created. This involves using variable vibration dampers with linear degrees of freedom in a floating mounting inside the cutter carrier. The damper position is set using a radially mounted setscrew, which allows optimum vibration conditions to be created. The improvement in surface qualities of bores is significant, as is the increase in the service life of cutter tools.

Inductive displacement sensors using the principle of the differential transformer (LVDT) can be used to measure displacement and, indirectly, magnitudes that can be converted into displacements such as force, pressure, strain, torque, vibration and so forth. Thanks to the high quality of their measurements, their high protection and long service life, these sensors are used in many technologies (industry, research, development, etc.). Applications include measuring, controlling, regulating and monitoring both slow and fast movements between machine parts, measurements of position and positional changes of components and structural foundations, servo regulators, valve and robot controllers, growth measurements and so on. Their design is robust - the internal coils and electronics are potted - as a result of which the sensors can easily withstand shock and vibration.

With an extended measuring range up to 45mm, the new eddy current sensor series completes the product portfolio of eddylab GmbH and at the same time combines all advantages of a non-contact eddy current measuring principle: With wear-free distance and displacement measurement, eddy current sensors are characterized by highest precision and dynamics. The new T14/T20/T40 series can withstand extreme temperatures in a range of -40...+150 °C without any problems and is insensitive to external influences such as dirt and dust. The new sensors with measuring ranges between 14 mm and 45 mm are also extremely compact and robust. This makes them ideal for use in difficult industrial environments or vibration measurements with larger amplitudes. Together with the TX electronics from eddylab GmbH and the eddy current software eddyMOTION, measurement data can be analyzed, visualized, and documented.

Displacement and all mechanical values which can be converted to displacements (e.g. compressive and tensile force, strain, torque and vibration) may be measured by this DC/DC displacement sensor. Typical application areas are the measurement of displacement and strain on machines, servo systems, vehicles, on test plants, in civil engineering and tunnel construction. An integrated maintenance-free electronic and a high-level DC output signal provide an easy handling without any problems. Displacement sensors of series 87240 convert a displacement into an analog electrical signal. They consist of a differential transformer with moveable core, an oscillator and a demodulator. These components are integrated and encapsulated in a cylindrical housing made of stainless steel. The sensors are energized by DC voltage, which is converted to AC by the oscillator and brought to the primary coil of differential transformer.

Linear displacements and mechanical values which can be converted to displacements (e.g. compressive and tensile force, strain, torque and vibration) may be measured by these DC/DC displacement sensors. The probe tip of these sensors is pushed onto the measuring object by a spring. This makes it possible to use these sensors were a mechanical modification of the measurement object (mounting hole) is not allowed or difficult. Output voltage as function of the displacement with the impedance as parameter. Sensors of series 87350 generally consist of an oscillator, a demodulator and a transformer with moveable core. They are energized by DC voltage. The oscillator uses this DC voltage to generate the carrier frequency, which is needed for the operation of the sensor. Dependent on the position of the core, which is made of ferromagnetic material, voltages are induced by the two secondary coils of the transformer.

It is increasingly important to make provisions and to keep one’s own machines in good condition. This reduces downtimes and prevents a decline in production. Our seamless diagnostics helps to ensure that machines run fault-free and enables advance planning of maintenance or repair work. The experts from LDW bring their equipment to the customer to inspect the machine on site. From partial discharge measurement through to vibration measurement – we clearly identify what technical state a machine is in. This allows downtimes to be planned ahead and ensures the efficient repair of the respective component.Diagnostics at our works in Bremen is even more effective, because we can directly consult an expert from the mechanical construction, electrical calculation or the R&D department for an assessment if necessary. The customers are provided with a comprehensive protocol after the measurements have been carried out. We then recommend the next steps for a repair or continued operation.

When using vibration transmitters, the vibration evaluation and the fault switch-off are outsourced, i.e. the alarm thresholds are parameterised in a separate evaluation unit or in a PLC that can record the trend development. Transmitters are current loop powered and output a normalised current signal corresponding to the vibration, which is then scaled in the system controller. The vibration transmitters of the 64x series are available with different measuring ranges and quantities (vibration velocity according to ISO 10816, vibration acceleration and vibration displacement, among others) that are related to the respective application. — Vibration transmitter with current output corresponding to the peak value of the vibration velocity — Measuring range 0 ... 12.7 mm/s — Output range 4 ... 20 mA — Frequency range 3 ... 1,000 Hz — 2-pin connection socket on top For an individual offer, please contact us directly.
