Velocity Sensor

The Metrix 5485C is a moving-coil velocity transducer, designed for con nous use in elevated temperatures up to 375°C. A zero-friction coil suspension provides accurate, repeatable vibration measurements over a wide range of amplitude and frequency and is built to withstand the high-g environments and cross-axis vibrations typical of gas turbines. The coil bobbin is suspended by two non-twisting, circular spider springs that provide a clean frequency response. Purely viscous electromagnetic damping is employed to eliminate friction-prone air damping and improving detect on of small vibrations amplitudes at low frequencies.
