Protection system accessories

SKF has a wide range of accessories to complement your distributed protection system. From software to machine condition transmitters and monitors, SKF has the accessories needed for the real time monitoring and protection of critical machinery.
CMSS 690 absolute shaft vibration (ASv) interface
The CMSS 690 ASv (fig 1) interface is an accessory interface device designed to provide absolute shaft vibration measurement capability for vibration monitor systems that do not offer this functionality. It enhances vibration monitor systems that do offer the absolute shaft vibration measurement, but lack access to raw sensor signals for external data acquisition devices. The CMSS 690 is an interface; it does not provide any protection or condition monitoring functionality.
CMSS 500 series of machine condition transmitters (MCT)
The CMSS 500 series of MCTs (fig 2) 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) results in a high density, low cost vibration monitoring system.

  • Low cost system for continuous condition monitoring
  • Compact DIN-rail mount, for both "G"-rail and "T"-rail
  • Two buffered acceleration outputs
  • 4-20 mA DC output signal
  • Small size due to surface mount technology (SMT)
CMCP 500 series monitors
CMCP 500 series monitors (fig 3) are compatible with vibration and temperature inputs; they provide a 4-20 mA output proportional to the overall measurement. Each unit provides power for the associated transducer, processes the signal to determine overall amplitude and outputs a 4-20 mA DC current that is proportional to a user specified range, such as 0-10 mils or 0-0.5 in/sec.

  • Alert, danger, and OK alarms and relays
  • Trip multiply
  • Remote reset
Transducers for machinery protections
  • Proximity sensors - eddy current probe systems
  • Industrial vibration sensors
  • High temperature accelerometer and velocity sensors
