HI 800 Series of Portable Shakers

Hardy shakers are instrumental in verifying the accuracy of vibration monitoring systems, an important concern for companies trying to maintain ISO 9000 certification.

The shakers provide a known vibration source that can be used to excite your field sensor in order to verify that the meter displaying the vibration value is correct. This test ensures that the integrity of your sensor, cable, signal conditioning electronics, and meter are functioning properly. The HI 803 model also checks the integrity of the sensor by sending the sensor output signal back into the shaker for comparison with the built-in  reference signal. The HI 803 calculates and displays the sensor's sensitivity
(e.g. 100 mV/g) and this may be compared with the sensor manufacturer's calibration sheet to determine if a replacement sensor is necessary.
