1. OVERVIEW
CJ701 Vibration velocity sensor
CJ701 series electromagnetic speed sensor is used to measure the bearing cap vibration of rotating machinery such as turbines, compressors, fans and pumps. It is a electromagnetic sensor outputs voltage by a moving coil cutting magnetic lines, so it does not need to supply power at work and easily installation
2. MAIN FUNCTIONS
2.1 Its output signal is proportional to the vibration velocity, and it can take account of the field of high-frequency, intermediate frequency and low-frequency vibration measurement.
2.2 The CJ701 series sensors have a lower output impedance and a better signal-to-noise ratio. Without special requirements on output plugs and cables, it is easy to use.
2.3 This sensor canceled activities friction components in design, so its flexibility is good, you can measure the slight vibration (0. 01mm) .
2.4 The sensor has a certain anti-lateral vibration capability (not more than 10g peak).
2.5 It can be used to measure the vibration of the bearing housing, enclosure or structure (relative to absolute vibration of inertial space).It can be directly mounted on the outside of the machine, and maintenance is extremely easy,
2.6 Its shell is made of stainless steel shell laser welding process, and its protection grade is IP65.
