Magnetoelectric IP65 Vibration Speed Sensor SZ-6 SZ-6A SZ-6G Series
SZ series magnetoelectric vibration speed sensor SZ-6 SZ-6A SZ-6G Zhonghe
System features:
SZ series magnetoelectric speed sensor is an inertial sensor. It uses the magnetoelectric induction principle to transform the vibration signal into a voltage signal, which is proportional to the vibration speed value. It can be used to measure the vibration of bearing pedestal, casing or structure (absolute vibration relative to inertia space). It is directly installed outside the machine and convenient for use and maintenance.
Main functional features:
◎ The output signal is proportional to the vibration speed, which can take into account the vibration measurement fields of high frequency, medium frequency and low frequency.
◎ SZ series sensors have lower output impedance and better signal-to-noise ratio. There are no special requirements for output plugs and cables, which is convenient to use.
◎ The sensor design cancels the moving elements with friction, so it has good flexibility and can measure small vibration (0.01mm).
◎ The sensor has certain anti-lateral vibration capacity (no more than 10g peak value).
◎ It can be used to measure the vibration of bearing pedestal, casing or structure (absolute vibration relative to inertia space). It is directly installed outside the machine and convenient for use and maintenance.
Technical Parameters
1. The output signal is proportional to the vibration speed, which can take into account the vibration measurement fields of high frequency, medium frequency and low frequency.
2. SZ series sensors have lower output impedance and better signal-to-noise ratio. There are no special requirements for output plugs and cables, which is convenient to use.
3. In the design of the sensor, the moving element with friction is eliminated, so it has good flexibility and can measure small vibration (0.01 mm).
4. The sensor has certain anti-lateral vibration capability (no more than 10g peak value).
5. It can be used to measure the vibration of bearing pedestal or casing or structure (relative to the vibration of inertia space). It is directly installed outside the machine, which is extremely convenient for use and maintenance.
6. The shell adopts the laser welding process of stainless steel shell, and the protection level can reach IP65.
