CMSS 797L, SKF, Low frequency industrial accelerometer, ring mode, side exit (XDCR, ACCL, RNG-MODE, LO FREQ)

The CMSS 797L is an industrial accelerometer for higher precision measurements at rotational frequencies as low as 12 r/min. These speeds are most commonly found in the following industries:
• Power Generation (Wind Turbines)
• Pulp and Paper
• Petrochemicals

Applications include rotors, rolls and extruders. The CMSS 797L combines a high sensitivity (to reveal low amplitude signals) with a narrow band of frequency response. The value of the high-pass filtering within the sensor makes it ideal for use in specialized, low speed analysis tasks using portable instruments or at specific measurement points on on-line systems. However, the low-pass filtering makes the CMSS 797L unsuitable as a general purpose accelerometer for rolling element bearing defect detection at more normal rotational speeds.

Features:
• Optimal for use with SKF on-line surveillance and protection systems and all portable data collection instruments
• 500 mV/g high sensitivity
• Ultra low-noise electronics for clear signals at very low vibration levels
• Low-pass filtered to attenuate high frequencies
• Hermetically sealed
• ESD protection
• Reverse wiring protection
