The MTN/1185 is a general purpose, top-entry velocity transducer with a 4-20mA output of the RMS velocity values. Sensors are constructed of stainless steel throughout for a robust sensor suitable for continuous vibration monitoring, even in harsh environments. Electrical connection options include a 3-pin 62GB connector, 2-pin MS connector, integral stainless steel overbraided ETFE or heavy duty PU cable. Mounting options include a quick fit, 1/4″ UNF or various mounting adapters to standard mounting threads. RMS velocity ranges available are from 0-10 mm/sec to 0-100 mm/sec. Versions available for hazardous areas and submersible use.
RMS Velocity Transducers
Velocity transducers are vibration sensors that provide a conditioned 4-20mA output proportional to the RMS value of the displacement velocity values of the vibration. The output shows displacement as a function of time and is provided in mm/sec. Velocity transducers are ideal for monitoring and control processes as they provide a stable output that can easily be monitored over time for variations.
The RMS (Relative Mean Square) is the square root of the averages of the square values of the AC sine wave of a vibration. The RMS value is therefore relative to the area under the curve of the AC sine wave. This allows the output to be a stable positive reading that is 0.707 times the peak value and is much easier to monitor over time for variations.
Any change in the normal vibration signal can indicate issues that need immediate attention to prevent damage to equipment. Changes in the vibration can indicate a piece of machinery is working loose from its mounting, fan blade malfunction, bearing failures or other machinery wear. Logging the vibration readings at regular intervals can be useful to highlight the gradual wear of part of a machine. This can also help to provide information on the expected life of machinery in any given application and allow for a suitable replacement to be purchased before a failure and limit the duration of any shutdowns caused by mechanical failure.
