Description
The MTN/1185IW Series is an ATEX and IECEx Group II certified velocity transducer suitable for monitoring RMS vibration in hazardous areas. The MTN/1185IW is an intrinsically safe, waterproof, top?entry velocity transducer with 2-wire proportional 4-20mA output. Stainless Steel construction allows for continuous vibration monitoring in harsh damp environments with an IP68 rating. Sensors are fitted with an integral heavy duty polyurethane cable and is available with a wide range of mountings.
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.
