Zhong he SZ-6G Magnetoelectric Velocity Sensor
The SZ series magnetoelectric velocity sensor is designed for measuring vibration in bearing covers of various rotating machinery including steam turbines, compressors, fans, and pumps. This electromagnetic sensor generates voltage through moving coil cutting magnetic lines of force, requiring no external power supply during operation and offering easy installation.
Key Features
- Output signal proportional to vibration velocity for high, medium, and low-frequency vibration measurement
- Low output impedance with excellent signal-to-noise ratio
- No special requirements for output plugs and cables
- Friction-free moving parts design for high flexibility and precise measurement of minute vibrations (0.01mm)
- Resistance to lateral vibration (up to 10g peak value)
- Suitable for measuring bearing housings, casings, or structural vibrations
- Stainless steel housing with laser welding technology for IP65 protection rating
