該儀器內(nèi)存容量較大，可存儲100組（X軸、Y軸、Z軸、總值）數(shù)據(jù)和8組3個方向的振動波形（1024點）。它配備了RS-232C接口，便于數(shù)據(jù)傳輸和進一步分析。顯示屏為LCD 128×64，能夠清晰地顯示測量結(jié)果和波形。電源為2節(jié)5號電池，連續(xù)操作時間可達18小時。此外，VM-90的環(huán)境溫度范圍為0～50℃，相對濕度小于95%RH，尺寸為200(H)×65(W)×32(D) mm。

VM-90三向軌跡測振儀廣泛應(yīng)用于機械制造、航空航天、汽車工業(yè)、電子設(shè)備等領(lǐng)域。它能夠幫助工程師和技術(shù)人員快速準確地檢測和分析設(shè)備的振動情況，從而提高設(shè)備的運行效率和可靠性。

The VM-90 three-axis trajectory vibration meter is a high-precision measuring instrument produced by RION, a Japanese company. Weighing only 230 grams, this portable and easy-to-operate device can simultaneously measure vibration velocity values and total values in three directions (X, Y, and Z axes) and display vibration velocity or displacement trajectory diagrams in any two directions. This unique measurement method gives it a significant advantage in the field of vibration analysis.

In terms of technical specifications, the VM-90 features a triaxial piezoelectric accelerometer probe and measures vibration velocity. Its measuring range is from 0.2 mm/s (RMS) to 70 mm/s (RMS), with a minimum measurable value of 0.1 mm/s (RMS) and a measurement accuracy of ±10%. Regarding frequency characteristics, the reference frequency is 80 Hz. The frequency range for the X and Y axes is 10 Hz to 1 kHz (±2dB), while for the Z axis, it is 10 Hz to 500 Hz (±2dB). Frequencies below 10 Hz and above 1 kHz are -18dB/oct.

The instrument has a large memory capacity, capable of storing 100 sets of data (X, Y, Z, and total values) and 8 sets of vibration waveforms in three directions (1024 points). It is equipped with an RS-232C interface for convenient data transfer and further analysis. The display is an LCD 128×64, which can clearly show measurement results and waveforms. Powered by two AA batteries, the VM-90 can operate continuously for up to 18 hours. Additionally, it has an operating temperature range of 0 to 50℃ and a relative humidity of less than 95%RH. The dimensions are 200(H)×65(W)×32(D) mm.

The VM-90 three-axis trajectory vibration meter is widely used in various fields such as mechanical manufacturing, aerospace, automotive industry, and electronic equipment. It can help engineers and technicians quickly and accurately detect and analyze the vibration conditions of equipment, thereby improving the operating efficiency and reliability of the equipment.

VM-90三向軌跡測振儀的市場價格一般在48000元左右。該儀器由日本理音公司生產(chǎn)，其產(chǎn)品以高精度和可靠性著稱。在中國市場上，有眾多經(jīng)銷商提供該產(chǎn)品的銷售及售后服務(wù)，例如北京時代天晨科技有限公司、廈門欣銳儀器儀表有限公司等。
