Long-Term Condition Monitoring- Elovis

 

LOGGING NODE measurement systems can be designed in combination with various internal and external sensors. The measured data can be monitored and recorded continuously, or periodically over several years. Measured data, alarms and preprocessed signals are wirelessly transmitted to a gateway which communicates the data within the network.

Compared to regular condition monitoring systems, the LOGGING NODE concept has the following advantages:

  • Extremely small and light weight concpet available
  • Extremely low energy consumtion concept
  • Easy installation and operation
  • Wireless to wireless network concept
  • Power supply with or without battery
  • Operation with our without gateway
  • Pre-triggered data logging
  • Automatic alarm mode

Description

 

Logging Node internal – LN-I

  • Periodic monitoring in adjustable time intervals
  • Integrated sensors:
    • Piezo acceleration sensor (0,3 Hz – 10 kHz)
    • Position sensor
    • Temperature sensor
  • Internal battery for operating times of 2 – 10 years
  • Vibration trigger to trigger measurement cycles
  • Memory for up to 4 million measurement values
  • Very compact dimensions: 50 x 50 x 20 mm3

Logging Node external – LN-X

  • Continuous monitoring of sensor signals
  • Starting measurement by trigger events or threshold violations
  • Pre-trigger: recording of signals even before a trigger event
  • Internal temperature, humidity, acceleration, strength sensors
  • Up to 4 inputs for external sensors
  • Flexibility by the use of modules for different sensor interfaces
  • Compact dimensions: e.g. 100 x 100 x 20 mm3

Logging Node external with battery – LN-XT

Same design and functions as the LN-X, but additionally:

  • Internal battery to power the measurement node and connected sensors
  • Battery life depending on used sensors and battery:
    • 1 – 5 years
  • Optional internal sensors possible:
    • Geophone
    • Acceleration sensor
    • Tilt sensor
    • Strength sensor
  • Optional modules possible:
    • Cellular radio connection
    • GPS for time synchronization
  • Solid industrial-standard housing
  • Dimensions: e.g. 220 x 120 x 80 mm3

Application Areas

LOGGING NODE systems are used whenever condition monitoring has to be done with a long duration.
Machine Condition Monitoring
 
LOGGING NODES allow an easy long-term condition monitoring of existing machines with minimal intervention. Thus, maintenance can be planned better and unexpected failures can be avoided. LOGGING NODES are used for example in power plants, in the chemistry industry, in big and complex machines with the high demand for long-term stability,…
LOGGING NODE systems measure vibration and other dynamic parameters periodically or continuously over a long time period. Evaluation of actual machine condition is done by comparing the actual measurement signals with typical signals in good condition. If the evaluation shows significant differences, an alarm is emitted.
Monitoring Structures 

LOGGING NODE systems are used in different application areas for monitoring structures:

  • Measurement of vibrations
  • Detection of changes in the building structure
  • Detection of critical situations
LOGGING NODES are operated fully independently and without external power supply. The sensors are monitored continuously. In the case of exceeding user-defined threshold values, measurement values will be stored and alarms can be triggered.
