Abstract
A hand-held or portable vibration sensor device having a housing and a sensor body which generally provides a single point of contact with the machinery or apparatus for which vibration measurement is desired. In one aspect, the sensor body comprises a vibration sensor element such as an accelerometer for measuring vibration. In another aspect, a force sensor such as a force sensing resistor or load cell is provided to reduce the impact of forces applied to said hand-held vibration sensor such as a force applied through a handle during measurement. In another aspect, a compensation circuit processes the out put from a vibration sensor element to provide a relatively flat frequency response over a desired operational frequency range. The hand-held vibration sensor may also comprise a rubber isolation member disposed between the sensor body and force sensor.
