In many monitoring applications non-contacting eddy current displacement sensor (ECDS) systems are the preferred sensor choice for a wide range of monitoring tasks. They are typically used for measurement of relative shaft vibration and displacement, as well as for use as reference sensors.
The CMSS 785 system is an eddy current type non-contact displacement/vibration system, used for measuring Shaft Vibration, Axial Position, Rotating Speed and Phase from small rotating machinery to large critical machinery in Hazardous and non-Hazardous environments. The CMSS 785 can be used in conjunction with the SKF On-line systems (IMx).
Vibration acceleration sensors for measurement of:
- Absolute casing or bearing housing vibrations
- High-frequency vibrations (e.g. up to 20 kHz)
- Vibrations in gearboxes Vibrations from rolling-element bearings
- Bearing condition
The CMSS 420 series are solid-state, loop-powered vibration transmitters. They provide a 4 to 20 mA, output that is proportional to overall vibration in terms of velocity. The series of CMSS 420 continuously monitor machinery health and transmit directly into a PLC or DCS for trending, alarm, and machine shutdown. In addition, the CMSS 420VT provides access to the dynamic transducer output. The buffered output is available for the temporary connection of portable analyzers for detailed machine fault analysis.
The CMSS 500 Series of Machine Condition Transmitters (MCT) are 4-20 mA transmitters. They convert part of the input signal to a 4-20 mA output proportional to the overall measurement and can be directly interfaced to an existing process control system (PLC or DCS). Combining transmitters with a programmable logic controller (PLC) or a distributed control system (DCS) result in a hight density, low cost vibration monitoring system.
