Svantek SVAN 974 – Class 1 Vibration Meter and FFT Analyser
The Svantek SVAN 974 is an advanced class 1 vibration meter and FFT analyser, designed for general vibration measurements and machine condition monitoring in accordance with ISO 20816-1. This compact and rugged instrument is ideal for maintenance engineers, consultants and R&D departments in industrial sectors. It provides parallel measurement of acceleration, velocity and displacement, supported by three independent vibration profiles with adjustable filters and RMS detector time constants for maximum flexibility.
The SVAN 974 performs real-time 1/1 and 1/3 octave analysis and FFT analysis, alongside optional RPM measurements using a Monarch laser tachometer. Measurement data is stored on a microSD card and is easily transferred via USB with the SvanPC++ software. With weighting filters such as VelMF, a colour LCD screen and power from AA batteries or USB, the SVAN 974 combines precision with ease of use in demanding environments.

When to choose the SVAN 974?
The Svantek SVAN 974 is a class 1 vibration meter and FFT analyser that excels in precision and versatility, designed specifically for condition monitoring and vibration diagnostics in industrial and R&D environments. With the ability to measure acceleration, velocity and displacement simultaneously via three independent vibration profiles, this instrument offers a great deal of flexibility. Each profile can be adapted with specific filters (e.g. VelMF) and RMS detector time constants, allowing engineers to capture several measurement parameters, such as RMS, Peak and Max, in a single session. This is useful, for example, when monitoring a rotating pump, where low-frequency imbalance and high-frequency bearing damage are analysed at the same time.
The real-time FFT analysis makes it possible to pinpoint vibration sources, such as faulty bearings or misalignment, by isolating frequency components, while the 1/1 and 1/3 octave analysis helps in choosing a maintenance strategy in accordance with ISO 20816-1. The optional RPM measurement with a Monarch laser tachometer provides additional insight into machine performance, for instance by linking vibration frequencies to the rotational speed of a motor. This is crucial in sectors such as power generation or shipbuilding, where downtime is costly.
For engineers and consultants who need accurate vibration measurements and advanced analysis, the SVAN 974 offers an excellent solution. Please feel free to contact us for a demonstration of this product by one of our specialists.
