Vibration Monitoring

The art of measuring low-frequency vibrations

Rotor blades in wind turbines are growing longer – but also slower.

Multimegawatt wind turbines turn even more slowly. This means that reproducible low-frequency vibration monitoring will gain in importance not only for the main rotor but also for the slow-operating gearbox components and roller bearings. Reliably measuring low frequencies, however, can be rather tricky.

VIBGUARD® XP with 20 synchronous channels

At the WINDENERGY tradeshow in Hamburg PRÜFTECHNIK Condition Monitoring presents VIBGUARD® XP, a new version of the proven Online Condition Monitoring system VIBGUARD® which is especially suited for the wind industry. VIBGUARD® XP fits perfectly

Visitors of the Maintain in Munich early June can rejoice.  PRÜFTECHNIK will be showing RS5, the new sensor for its proven measurement system OPTALIGN Smart RS.

Monitran’s MTN/1100-R accelerometers are ideal for long-term vibration monitoring in harsh radiation environments. 
Monitran, a leader in the development and manufacture of transducers for the measurement of vibration, proximity and displacement, has launched the MTN/1100-R series of radiation-resistant constant current accelerometers.
Developed for use in nuclear power stations, the sensors, which are top-entry and sealed to IP67, have a radiation resistance of 10Mrads and are well-suited for long-term vibration monitoring in a variety of harsh radiation environments.
Andy Anthony, Managing Director of Monitran, comments: “As a manufacturer of sensors, and with our talented engineering department, we pride ourselves on being able to develop and make fit-for-purpose sensors, whatever the requirements.”

Monitran's new hand-held meter, the MTN/VM220, is ideal for detecting the early signs of component wear or failure in pumps, motors, gearboxes and other mechanical assemblies.

Southern Manufacturing & Electronics, Farnborough, United Kingdom – Monitran, a leader in the development and manufacture of transducers for the measurement of vibration, proximity and displacement, has launched the MTN/VM220; a compact, handheld meter for measuring vibration and temperature levels.

The MTN/VM220 conforms to ISO10816-3 and is ideal for detecting the early signs of component wear or failure in machinery, motors, gearboxes, pumps and other mechanical assemblies. The meter includes a crisp, colour LCD display and has the ability to store up to 100 readings (temperature and acceleration, velocity or displacement) against a real-time clock.

Measuring just 122 x 78 x 28mm, the MTN/VM220 has an easy-to-grip, tough rubberised case and a long-life rechargeable battery. It is supplied with a probe into which is integrated a dual-output, general purpose sensor, the MTN/2200T, which has default sensitivities of 100mV/g and 10mV/oC. Also included are a magnetic base and spike (for use with the probe), a coiled cable (0.5m nominal to 2m extended) with a 4-pin Lumberg connector at each end, and a universal (battery) charger; all in a foam-lined and durable carry case.

Andy Anthony, Monitran's Managing Director, comments: "We're extremely pleased with the look, feel and performance of our new vibration meter. Also, having hinted late last year that the meter was to be launched at Southern Manufacturing & Electronics, we've already received enquiries and advance orders from customers in the UK and abroad."

The MTN/VM220 is available immediately.
