VKV021 Vibration Monitor DIN ISO 10816 0-25mm/s | IFM

The Original New IFM VKV021 Vibration Monitor is a permanent vibration monitoring device designed for predictive maintenance and machine health assessment in industrial automation systems. It measures the overall vibration velocity according to DIN ISO 10816 and provides both a switching output with adjustable switch point and response delay, and a 4-20 mA analog current output proportional to vibration velocity. Simple switch point setting by means of two setting rings allows intuitive on-site configuration without additional software or programming tools.
