VTV121 Applications

The VTV121 is a vibration transmitter to ISO 10816 for continuous condition monitoring of rotating machinery such as pumps, fans and motors. Using a MEMS sensing element, it measures effective vibration velocity (RMS) from 0...50 mm/s over a 10...1000 Hz frequency band and outputs a proportional 4...20 mA signal in 2-wire technology. Its rugged 316L stainless steel housing, IP 69K protection and wide -30...125 °C temperature range make it suitable for harsh industrial environments and permanent installation.
