HI 803/813 portable vibration shakers

Metrix HI 803/813 portable vibration shakers are designed to be used in the field or shop to verify the performance of vibration transducers, connectors, cabling, instruments or permanently installed condition monitoring systems. Both models are battery-powered, portable and feature a built-in reference accelerometer and indicator with calibration traceable to the National Institute of Standards and Technology (NIST).

These shakers can easily check velocity transducers, accelerometers and non-contacting Eddy Probe displacement measurement systems. Simply attach the transducer to the shaker head (displacement probes require a mounting fi xture and target), set the shaker to a known vibration reference level, and verify readings. The reference test level can be set in acceleration, velocity, or displacement, English or Metric.

The HI 803 Shaker Deluxe

This top-of-the-line Metrix shaker includes more operational functions. In manual mode, the vibration test level and test frequency can be set from 10 Hz to 10,000 Hz. In sensitivity mode, the HI 803 not only vibrates the transducer being tested, but also measures its output and calculates its output sensitivity. A built-in display reads the output sensitivity, which can be stored in memory. Complete testing sequences and data can be stored in memory for each tested sensor, and a built-in printer logs data on the spot or stores it for later.

An RS232 port and data transfer program are standard, and ASCI II test data files are easily transferred to a computer. For testing of heavy transducers or at high frequencies, the HI 803 automatically corrects the sensitivity calculation for the effects of transducer mass loading. It also measures and displays transducer phase, which is important in balancing applications. A built-in self test program checks for accuracy of all calculations.

Metrix HI 813

Used for testing from 25 to 10,000 Hz, the Metrix HI 813 Shaker offers adjustable frequency and adjustable vibration level. This provides a reference source for verifying the accuracy of vibration transducers, connectors, cabling and instruments or instrumentation systems. To find intermittent cables or loose connections requires testing in the frequency range of 500 Hz to 2,000 Hz.

The HI 813 has a ruggedized suspension system that can support heavy transducers (up to 750 grams) that require testing in a horizontal direction, instead of the normal vertical direction. This added support makes this shaker a good choice for heavy duty field use. The HI 813 has a built-in battery charger that can operate on 120 or 240 VAC.
