Machine health monitoring from SKF

June 2014 Sensors & Transducers

SKF has launched the SKF machine condition indicator, a low-cost vibration and temperature monitoring device designed for rotating machinery with constant operating conditions. It provides the ability to track basic machine health on assets that are not currently being monitored on a regular basis. The device can be used indoors or outdoors, in almost any industry where rotating machines are used, such as pulp and paper, power, food and beverage, oil and gas as well as HVAC.

The indicator periodically makes two types of vibration measurement. Velocity measurements are made to keep track of overall machine health and highlight potential problems relating to misalignment and imbalance and envelope acceleration measurements are used to detect possible bearing degradation. In addition, the device monitors machine operating temperature. The unit features built-in intelligence for measurement evaluations and to avoid false alarms, with an alarm status visually indicated via three LEDs. The indicator is fixed to the machine and runs off battery power.

“The SKF Machine Condition Indicator is as simple as the ‘check engine’ warning light in a car,” says Torsten Bark, product line manager at SKF Condition Monitoring Centre, San Diego. “Once LEDs are illuminated, it alerts the predictive maintenance technician to do a root cause analysis on the machine to determine what kind of problem might be affecting its performance.”

By utilising the SKF Machine Condition Indicator, plant operators can save both time and money by freeing up maintenance engineers to spend less time on problem detection and more time focusing on root cause analysis and other more significant issues. In addition, maintenance schedules for non-critical machines can be assigned at less frequent intervals, as the installed indicator will provide feedback via its LEDs.

It is a good solution for manufacturers looking for cost effective ways to ensure that machine assets are kept running. The indicator runs on a high energy lithium battery and has a life expectancy of more than three years.
