Wireless Vibration Sensor with RV (Raw Vibration)
Output operates identically to the standard model, plus, it provides a raw vibration output
signal for detailed diagnostic analysis. The unit has a connector on the side of the housing
that can be used with an optional Model 070A86 Echo
®
RV Output Cable that provides
the analog acceleration signal directly from the embedded accelerometer.
The cable converts the standard constant current sensor power provided by most data
collectors to the low voltage supply required by the Echo
®
Sensor. To make raw vibration
measurements, remove the shorting cap on the RV output connector. Attach the 4-pin
connector on the cable to the RV output connector. Connect the BNC end to a data
collector and set sensor power to on in the data collector. The nominal sensitivity of the
raw signal is 100 mV/g and there is a ± 20 g range.
Note
: Replace the shorting cap after raw vibration data is collected. Wireless operation of
the sensor will not work with it removed.
