Accelerometer speeds collection of vibration data collection

By Control Engineering Staff November 14, 2005

Emerson Process Management introduced a triaxial accelerometer with integral magnet that is smaller than conventional triaxial accelerometers, delivers excellent measurement quality, and speeds data collection in the field by technicians using the dual-channel CSI 2130 Machinery Health Analyzer, the company says.

Emerson’s new triaxial accelerometer decreases implementation costs because it does not require a stud mount for monitoring rotating equipment. Instead, it can be magnetically attached on a mounting pad and deliver measurements up to 10 kHz in the primary axis and above 3 kHz in the secondary axes. When used with Emerson’s PeakVue technology, the sensor’s high frequency response range identifies bearing faults and improper machine lubrication, ensuring users are made aware of these potentially damaging conditions, the company suggests. Using this approach, data on a typical bearing point can be gathered in 7 to 10 seconds, which is 30-75% faster than with conventional approaches, Emerson says.

The sensor can also serve in general monitoring applications as a single-axis sensor without special mounting. It can be placed directly on the machine housing, even curved surfaces, and provide quality data.
