General Specifications
Description
The 7014 combines the cost effectiveness of utilizing commercially available
accelerometers with the flexibility and power of wireless communication. The
unit contains a constant current power source, amplifiers, filters, digital
signal processor, data memory, wireless transceiver, internal battery and an
internal antenna. Powered with an internal Lithium battery, the unit
collects and transmits vibration and temperature data securely via a
wireless link to a Network Access Point (NAP). The 7014 is a component of the Maintenance
Watchdog System which provides all the tools needed to collect and analyze
vibration data.
Applications
- Condition Based Maintenance
- Vibration Monitoring
- Vibration Analysis
- Machine Diagnostics

* This accuracy assumes the sensor is 100mV/g.
Any deviation of the sensor from this value will result in additional
amplitude errors in the readings. Frequency information will be unaffected.
** The product can be operated (powered) over the full -40º
to 85º
C range, however the radio link is only guaranteed over the -20º
to 50º
C range.
