Product Description

The IFM VTV122 is a compact, industry-standard vibration transmitter designed for permanent condition monitoring of rotating machinery. It measures RMS vibration velocity (ISO 10816) in the 10–1000 Hz range, converts it directly to a 4–20 mA signal proportional to 0–25 mm/s, and provides an additional PNP switching output for alarm thresholds. With M12 connector, robust stainless-steel housing, and integrated evaluation electronics, it enables easy retrofitting without the need for an external analyzer.

Standard Features

  • True RMS velocity measurement: Direct ISO 10816-compliant 0–25 mm/s RMS output – the most widely accepted vibration severity parameter for industrial machines.

  • Loop-powered 4–20 mA output: Can be wired directly into PLC analog inputs or DCS over long distances without additional power supply.

  • Integrated switching output: PNP switch triggers at user-adjustable alarm level (via IO-Link or teach button) for early warning or shutdown.

  • Rugged and reliable: Full stainless-steel body, IP67/IP69K, and -30°C to +125°C operating range – proven in harsh environments worldwide.

  • Plug-and-play commissioning: Pre-configured for typical machines; fine-tuning of switching point via single pushbutton or IO-Link.
