SKF has released the handheld Machine Condition Advisor (MCA) device that can simultaneously measure vibration signals and temperature to assess the condition of rotating equipment such as motors, pumps, compressors and conveyors.
SKF says the pocket-sized MCA allows maintenance technicians and plant operators to monitor machinery without any specialist expertise.
According to SKF, the MCA’s tip is pressed against the part of the machine to be checked, which is typically a bearing. Once the readings stabilise, the user presses a button to hold the values, which can then be read and recorded.
SKF says the vibration signals are then compared with pre-programmed ISO guidelines, while an ‘enveloped acceleration’ technique is used to compare the readings with established bearing vibration guidelines. If the measurements exceed these guidelines, an alert or danger alarm is shown.
According to SKF, the MCA has an infrared temperature sensor, which checks for abnormal bearing temperatures at the same time. Abnormal temperatures can indicate lubrication problems.
The MCA can measure vibration signals from ten to 1000Hz and temperatures from -20 to 200 degrees Celsius. It is powered by a rechargeable lithium-ion battery and features a backlit LCD display. An optional external vibration sensor can be fitted for use in tight spaces.
