YMC Series Piezoelectric Vibration Velocity Sensors are solid state piezoelectric velocity measurement devices. Many vibration
analysis prefer to examine vibration signals in terms of velocity (mm per second) to amplify the signal of interest. Piezoelectric
Velocity Sensors inherently decrease high frequency signals allowing better measurement of low frequency vibration. They are
essentially accelerometers with an internal integration circuit which will produce an output relative to velocity.
Features:
（1）Output proportional to vibration in velocity
（2） Mount at any angle
（3）Transmit signals over long distance without signal loss(4-20mA)
（4） Output to PLC, DCS, SCADA
YMC Series the High Shock Accelerometer is specifically designed to withstand and measure extremely
high–amplitude, transient acceleration of short duration. This series features high stiffness, quick response and
high value of acceleration. It is widely applied in drop & impact testing and explosive studies etc. Measuring range
is from 1000 to 100000g.
YMC LA series Power Amplifier are designed to drive MS series Modal Shakers and MS series
small vibrators. Features:
（1）Adjustable RMS output–current limit
（2） Low or high output impedance
（3） Low distortion over wide frequency range
（3） Extensive built–in protection
（4）Operating mode (current or voltage), current state and interlock input disabled
（5）Rear panel voltage and current monitor points
（6）Multifunction display (True Colour LCD) showing approximate output current and
output voltage, clipped output signal, temperature overload, current overload.
（7）LA60 and LA–100 power amplifier is built–in Sine signal generator from 5Hz to
30kHz with 60/100VA power output.
YMC IH series Impact Hammer integrates a rugged, force sensor into the hammer’s striking surface. Variety of
hammers are suitable for different size test subjects. Assortment of tips offer frequency tailored impulse. Used
for structure health testing, resonance determination, modal analysis.
