VC-220 Vibration Comparator

Monitor production facilities - check vibration & sound

The VC-2200/3200 is a Vibration comparator which is used for maintenance and constant monitoring of production facilities with high accuracy, high function, and low cost in a single unit.

The VC-2200/3200 Vibration Comparator utilises high-speed calculation by employing a digital signal processor (DSP) in DIN size. Newly installed TEDS function enables high performance calculation, time reduction, and less human errors in setup.

From the output signal of an accelerometer, the VC-2200/3200 simultaneously records two different frequencies with one unit. Data is easily managed with a PC. The VC-2200/3200 has multiple roles including detection, judgment, and data management.

The VC-2200/3200 features checking of "visual and auditory". It has function of checking vibration with sound by connecting headphones together with checking the vibration on-screen via numerical displays and bar graphs.

The "comparator gate input function" can extract vibration phenomenon by controlling the timing signals from a PLC. All of these functions are packed into a compact DIN size (96mm X 96mm).
