Description

The MTN/1185W is a submersible velocity transducer with an integrated polyurethane cable and it can be completely immersed in liquid (max 5m) for permanent installation. The integral cable also makes this sensor suitable for application involved sprayed liquids rather than being completely immersed, such as cutting fluid on machine tools or on water pumps where the chance of a leak may affect the sensor. The Stainless Steel construction and IP68 rating allow the MTN/1185W to be used for continuous vibration monitoring in harsh underwater environments.

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.

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 failures.

Underwater RMS vibration monitoring
Equipment vibration monitoring in submerged environments
Vibration montoring in submersible or very damp conditions
