SZ Series Electromagnetic Velocity Sensor Zhonghe SZ-6 SZ-6A SZ-6G

1 OVERVIEW
SZ series electromagnetic speed sensor is used to measure the bearing cap vibration of rotatingmachinery such as turbines, compressors, fans and pumps. It is a electromagnetic sensor outputsvoltage by a moving coil cutting magnetic lines, so it does not need to supply power at work andeasily installation.

2 MAIN FUNCTIONS
2.1 Its output signal is proportional to the vibration velocity, and it can take account of the field ofhigh-frequency, intermediate frequency and low-frequency vibration measurement.

2.2 The SZ series sensors have a lower output impedance and a better signal-to-noise ratio. Withoutspecial 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 canmeasure the slight vibration (0.0lmm).

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 toabsolute vibration of inertial space). It can be directly mounted on the outside of the machine, andmaintenance is extremely easy.
