Leonova Diamond®

A three-channel portable analyser designed for harsh industrial environments. It combines spectrum resolution up to 25,600 lines from DC to 40 kHz, SPM HD shock pulse measurement, single and dual plane balancing, and laser shaft alignment in one instrument.

Highlights

  • 3-channel simultaneous vibration measurement, 24-bit A/D converter
  • DC – 40 kHz frequency range, max. 25,600 lines
  • SPM HD®, HD ENV, EVAM and dBm/dBc shock pulse methods
  • Single and dual plane balancing, laser shaft alignment
  • 4.3" colour TFT display, IP65 housing, –20 / +55 °C
  • CondID® NFC measuring point identification

Why Leonova Diamond?

Leonova Diamond is the top-tier instrument for route-based condition monitoring programmes. With synchronous measurement, enveloping, true zoom and spectrum resolution up to 25,600 lines across DC–40 kHz, it offers full vibration analysis capacity. The broadband evaluation tables of ISO 10816 for velocity, acceleration and displacement are built into the instrument.

Always included

  • Data logging and route transfer with Condmaster® Ruby
  • ISO 2372 vibration monitoring
  • Speed and temperature measurement
  • Analog signal, current and voltage inputs
  • Automatic recording, up to 50 hours
  • Electronic stethoscope function
  • Reading from and writing to CondID® memory tags
  • Recording of vocal comments

Balancing and alignment

For single and dual plane rotor balancing, a graphical guide calculates balancing weights and their positions. Shaft alignment uses a modulated line laser beam and high-precision inclinometers; because the angle of rotation of both detector units is measured continuously, measurement runs in fully automatic mode with much less than half a turn of the shaft. Results are displayed in hundredths of a millimetre.

Frequently asked questions

What is the difference between Leonova Diamond and Leonova Emerald?

Leonova Diamond measures vibration on three channels simultaneously, offers resolution up to 25,600 lines across DC–40 kHz, and supports dual plane balancing and laser shaft alignment. Leonova Emerald is single-channel, reaches 12,800 lines across DC–20 kHz, and performs single plane balancing only. Orbit analysis, shaft centreline plotting and 3-channel simultaneous measurement are available only on Diamond. Emerald is the more economical choice for programmes focused on route measurement and bearing monitoring.

Why does SPM HD technology help at very low speeds?

Conventional vibration measurement detects bearing damage late at low speeds because the energy produced is very small. SPM HD amplifies the high-frequency shock waves generated by bearing surface contacts through order-synchronous sampling and digital signal processing. This makes it possible to detect damage months in advance on wind turbine main bearings, rotary kilns and heavy mixers running at speeds as low as 0.1 rpm.
