4-118 Applications • Vibration Analysis and Monitoring • Dynamic Balancing Equipment • Engineering Test and Research • Production and Quality Testing Features • Miniature, for space limited applications • Self-generated, high level, low impedance output • Operates to +500°F (+260°C) • Weighs only 2.2 ounces Description CEC’s miniature 4-118 Vibration Transducers are especially valuable where space is limited, and where heavier transducers would invalidate your results. These transducers can be used in high temperatures, have low sensitivity to transverse accelerations, and can be mounted in any plane. The measurement system is simplified because the low impedence, high level output can drive AC meters and recorders without using special amplifiers. These features make them suitable for many applications on jet engines, turbines, high speed motors, superchargers, internal combustion engines and in test cells. CEC’s 4-118 Vibration Transducers use a seismic mass coil, suspended by springs, high flux magnet is attached to the base. The output signal results from relative movement between the magnet and coil when the case is in motion. This magnetically damped system operates above its natural frequency so the output is proportional to velocity. The gold-onsapphire bearings provide nearly friction-free movement, extending the instrument life and reliability. These instruments are available in two configurations: the 4-118-0001 with an integral cable, and the 4-118-0002 with a top connector for a detachable cable. moving on bearings of gold and sapphire.
