  • CEC Vibration Products 4-102 & 4-103 Vibration Sensor 振动传感器

    Features:","Applications:","Description:","The fluid-damped moving elements in CEC’s 4-102 and 4-103 Vibration Transducers are free of friction, assuring long life and reliability. This frictionless design also features outstanding dynamic range. It can be used to measure displacement to 0.5 inches, with low-levels limited only by system noise.","These transducers are used to measure vibration in many applications, such as fans, high speed motors, rotating machinery, in test cells and on dynamic balancing equipment. The output signal is proportional to velocity, often considered the best measurement for machine health monitoring. The low impedance, high level output can drive AC meters and recorders without using special amplifiers, simplifying your system.","These transducers use a seismic mass magnet suspended by springs, and a coil fixed to the case. The output signal results from relative movement between the magnet and coil when the case vibrates. The system is fluid-damped, and operates above its natural frequency. The special C springs, which support the mass, withstand high transverse accelerations and rough handling. Positive hermetic sealing prevents damage to the instrument when used in severe environments.
  • CEC Vibration Products 4-123 Vibration Sensor 振动传感器

    Features:","Applications:","Description:","CEC's 4-123 Vibration Sensors are particularly suited to turbine applications. They operate to +500°F, have low sensitivity to transverse accelerations, and can be mounted in any plane. The low impedance, high level output requires no special amplifiers, simplifying your measurement system. Precision jewel bearings provide nearly friction-free movement for long life reliability.
  • CEC Vibration Products 4-118 Vibration Sensors 振动传感器

    功能:,应用:,说明:,CEC的微型4-118振动传感器在空间有限的地方尤其有价值,而且较重的传感器会使您的结果无效。这些传感器可以在高温下使用,对横向加速度的灵敏度很低,并且可以安装在任何平面上。由于低阻抗、高电平输出,无需使用特殊放大器即可驱动交流仪表和记录仪,因此测量系统得以简化。这些特性使其适用于喷气发动机、涡轮机、高速发动机、增压器、内燃机和试验室的许多应用。
