Instrumentation
While the CSI 6500 delivers eld-based intelligence, accurate information starts with quality instrumentation.
Eddy current displacement sensors are the preferred method for monitoring sleeve-bearing machines. These displacement sensors penetrate the machine case and directly monitor the motion and position of the shaft without contacting the shaft surface.
Accelerometers and velometers are the industry accepted sensors for monitoring the health of gearboxes and rolling element bearings. Although temperature sensors are sometimes used to measure health, temperature alone is only a small part of the machinery health picture. When a shaft begins to rub the bearing as a result of misalignment, a displacement probe can directly track the misalignment behavior. By the time the rub is severe enough to trigger a temperature alarm, the damage is already done.
Mounting location and instrumentation bracket design are both critical for quality data.
A complete range of sensors, adapters, cables, connectors, converters, and ttings are available for new installations, retro ts, or replacement of sensors during an overhaul.
