Product Overview
The SensorsX SX-MVPNA Series is a piezoelectric vibration velocity transmitter designed for industrial machinery condition monitoring. Featuring a built-in signal conditioning circuit, it provides a standard 4–20 mA analog output with a measurement range of 0–20 mm/s RMS and a frequency response of 10–1,000 Hz (±5%). Its stainless-steel housing, compact design, and 2-pin electrical connector make it suitable for vibration monitoring of motors, pumps, compressors, and other rotating machinery.
