IFM VTV121 Vibration Transmitter 0-50mm/s 4-20mA IP69K MEMS

Overview
The IFM VTV121 is a high‑precision vibration transmitter designed for reliable permanent monitoring of overall vibration according to DIN ISO 10816. Utilizing MEMS (microelectromechanical system) technology, this 2‑wire device continuously measures RMS vibration velocity across a frequency range of 10…1000 Hz, making it suitable for predictive maintenance and condition monitoring of rotating machinery such as motors, pumps, fans, and compressors. The precise linearized 4…20 mA analog output provides seamless integration into PLCs, SCADA, or frequency converters for real‑time vibration monitoring. Housed in a compact stainless steel (316L/1.4404) cylindrical enclosure with triple‑rated IP67, IP68, and IP69K protection, the VTV121 withstands dust, continuous immersion, and high‑pressure, high‑temperature washdowns. With a wide ambient temperature range of -30…125 °C, shock resistance up to 500 g, and an MTTF of 868 years, this transmitter is built for long‑term reliability in demanding industrial applications including food processing, machine tools, and outdoor installations.
