PRODUCT DATASHEET Milli-VibVibration Sensor APPLICATION VIBMIL is a vibration sensor designed for continuous monitoring of vibration levels in industrial environments. It is current loop powered accelerometer and delivers accurate vibration RMS velocity using a 420 mA output. Built with a stainless-steel enclosure, including a 3/4” NPT thread for conduit connection. METHOD OF OPERATION The VIBMIL is equipped with female 1/4”-28 UNF female mounting thread, allowing the use of a screw, stud, or mounting stud to secure the sensor to the desired application. The sensor is supplied with a 1/4”-28 UNF set screw as standard. Optional converters to M8 and M6 male threads are available. To achieve maximum sensitivity, mount the sensor vertically along the Y-axis of the machinery. To ensure accurate readings and proper functioning of the VIBMIL, securely fix it to a level surface during installation. Implement the 2 wire, loop powered accelerometer into the desired control system and measure the linear output from 4 - 20mA proportional to the sensors measuring range.
