Magnetoelectric Vibration Velocity Sensor

The YMC 321V series magnetoelectric speed sensor consists of a magnet, a coil and a damping element. Relative motion of magnet and coil under vibration generates an induced potential — a mechanical-to-electrical energy conversion sensor.

The YMC 321V series magnetoelectric speed sensor consists of a magnet, a coil and a damping element. Relative motion of magnet and coil under vibration generates an induced potential — a mechanical-to-electrical energy conversion sensor. It needs no external power supply, has a simple circuit, a stable signal and low output impedance, and suits vibration, speed and torque measurement. Two test directions are available: horizontal (suffix H) and vertical (suffix V).

Typical applications

• Vibration measurement on rotating machinery
• Speed and torque measurement
• Self-generating measurement where no power supply is available

Main parameters

• Measuring range — 20 ~ 100 mV/mm/s (optional)
• Measuring direction — Horizontal (H) or vertical (V)
• Frequency range — 5 Hz ~ 1 kHz
• Size — Φ41×57 mm
• Weight — 250 g
• Output mode — Voltage, 4 ~ 20 mA optional
• Power supply — None required (self-generating)
