CMAS 100- Dụng Cụ Đo Rung Động Cơ Bản

Dụng cụ giám sát thiết bị: Giám sát thiết bị là quá trình xác định tình trạng của máy trong quá trình hoạt động. Thành công trong việc sử dụng chương trình này giúp cho việc sửa chữa các bộ phận có lỗi trước khi nó bị hư hỏng thực sự. Giám sát tình trạng thiết bị không những giúp quản lý nhà máy giảm thảm họa hư hỏng mà còn cho phép họ đặt hàng trước, lên kế hoạch về nhân sự và kế hoạch bảo dưỡng sửa chữa trong quá trình tạm dừng máy

Mô tả

Features
• Quick and easy to set up and use, measurements are shown on a bright display viewable in low light to direct sunlight. Free on-line training is also available at SKF @ptitude Exchange.
• Lightweight, compact, and ergonomically designed, the SKF Machine Condition Advisor fits neatly at the belt line, in a pocket or a tool kit. Exceptionally durable, the unit is rated IP 54 for use in industrial environments.
• Alert and Danger prompts provide increased diagnostic confidence.
• Measuring velocity, enveloped acceleration and temperature simultaneously saves time.
• Efficient, economical and environmentally friendly, the rechargeable SKF Machine Condition Advisor operates 10 hours on a single charge.
• Flexible enough to work with standard 100 mV/g constant current accelerometers, an optional external sensor can be used for hardto-reach locations and for more repeatable and accurate measurement results.
• Features English, French, German, Portuguese, Spanish and
Swedish for user convenience.

Multiple measurements with a single device The SKF Machine Condition Advisor provides an overall “velocity” vibration reading that measures vibration signals from the machine and automatically compares them to pre-programmed International Organization for Standardization (ISO) guidelines. An “Alert” or“Danger” alarm displays when measurements exceed those guidelines.Simultaneously an “enveloped acceleration” measurement is taken and compared to established bearing vibration guidelines to verify conformity or indicate potential bearing damage. The SKF Machine Condition Advisor also measures temperature using an infrared sensor to indicate uncharacteristic heat. Accuracy, flexibility and confidence When performing measurements, the SKF Machine Condition Advisor’s acceleration sensor input signal is processed to produce two different measurements for each POINT on the machinery-overall velocity and enveloped acceleration.
