The M/RAD Model WIN437 Digital Vibration Monitor is a PC based instrument that will instantly provide vital vibratory information including Acceleration, Displacement, Frequency and Velocity readout. Furthermore, specimen and shaker protection are supplied with over and under "g" limits which may shut down the machine upon activation. The monitor contains these functions in an Acquisition Card which is situated in a PC that uses a PCI slot. The accelerometer is interfaced with an M/RAD supplied Interface Box which is attached to the Acquisition Card. No accelerometer pre-conditioner or other laboratory instruments are required. Confidence and protection of the test specimen while vibration testing are assured.
