Vibration monitoring of motors

October 2002 Sensors & Transducers

In order to facilitate the cost-effective condition monitoring of motors in a wide range of manufacturing and industrial processes, Monitran has developed the Defender MTN/410 vibration sensor. Available from Temperature Controls and suitable for DC and AC, single- and variable-speed motors and gearboxes, the Defender MTN/410 is a suitable 'low-cost, entry-level' vibration-monitoring unit.

By providing the means with which to regularly monitor the performance of motors and gearboxes, the Defender MTN/410 enables maintenance engineers to easily predict when repairs or replacements are required. This allows for considerable savings to be made in both time and money, as maintenance windows can be managed more effectively and downtime significantly reduced.

Suitable for production and manufacturing equipment such as machine tools, industrial presses, automation systems and packaging lines, Monitran's latest vibration sensor is also useful for remote monitoring.

Requiring no external power source, the Defender MTN/410 is good for use in remote locations and applications where the performance of motors needs to be monitored regularly, but where the cost of a fully integrated condition monitoring system would otherwise be prohibitive. Typical applications include motors in dust and fume filtration systems, as well as ventilation systems found in public places such as underground car parks.

Its small dimensions make it ideal for difficult-to-reach locations or applications where space is limited, while its variable-position mounting unit makes for quick and easy mounting on any plane.

The Defender MTN/410 comprises a number of unique features including a built-in, two-digit LCD display, five-year lithium manganese battery and an innovative acceleration switch. Sensitive to sudden motion and used to activate the sensor, the acceleration switch ensures a sharp tap on the casing is all that is required to start the Defender MTN/410 operating. The unit automatically shuts down after a pre-determined interval to prolong battery life still further.

Based on proven sensor technology and featuring an integral microprocessor, the Defender MTN/410 is constructed from stainless-steel components and casing. The monitor is accurate, with a displayed velocity range of 0 to 99 mm/s RMS and a measurement bandwidth of 6 Hz to 1 kHz. Each unit is sealed to IP65 and can operate at temperatures ranging from -20 to +85°C. Monitran is marketed and supported in southern Africa by Temperature Controls.
