The development of Bently Nevada vibration velocity sensors and accelerometers began with velocity sensors, which provided a self-generating electric coil design used by geologists to measure the movement of the Earth's crust. Today, we still refer to "seismic" sensors as their point of origin. These early sensors gave rise to rugged solid-state accelerometers, which were later introduced as today's integrated accelerometers, which use velocity rather than acceleration to deploy signal processing circuitry for the output signal.
Acceleration and Velocity Sensor Product Features: Both acceleration and velocity sensors have features that help keep your machines running at their best. Both can handle extremely high temperatures. Velocity sensors are self-powered, radiation-resistant, and flexible, suitable for your plant, while acceleration sensors protect against
