| | | Self-Generating vibration transducer, 20mV/mm/s output, +200°C operation and broadband velocity performance 4.5Hz - 2KHz. The VEL-G series of Vibration Transducers are robust, sealed instruments suitable for operation in heavy industrial environments. This self-generating transducer produces a signal proportional to the velocity component of a mechanical vibration by means of relative movement between a coil and a magnet.The signal level is suitable for direct connection to most signal conditioning and data recording equipment. The main body of the transducer is fitted with a polished stainless steel case and contains a moving coil and magnet assembly. The coil is suspended within the field of the magnet by means of diaphragms, which permit virtually frictionless movement in one axis only. This measuring axis is coincident with the axis of the cylindrical body. | | |
