For Leak Detection and Testing Bearing Lubrication


GTILube Route-Based Ultrasound Lubrication

Under and over lubrication of bearings are major causes of bearing failure. GTILube is a simple app that uses UE Systems sensor technology to baseline and measure changes in the ultrasound signal to determine when a bearing needs lubrication. GTILube uses NASA standards for ultrasound measurement – an 8 dB increase signals a need for lubrication. A 12 dB increase indicates early bearing failure.

GTILube includes a calculator for determining an acceptable amount of lubrication for the bearing based on its geometry. This value is displayed on-screen when the measurement exceeds the Alert level. Users can also enter and display the type of grease for each bearing.

GTILube uses GTI Hierarchy technology for simple set up of routes and measurements. Bearing geometry is added during measurement set up. Users can accept the initial measurement as a baseline or enter a custom baseline value.


Ultrasonic Analyzer

Ultrasonic Analyzer is a real-time spectrum,spectrogram, oscilloscope and octave RTA analyzer for your iPad. It provides a visual representation of many ultrasounds using a sampling rate up to 384kHz. The app can record, analyze and use slow down playback for sounds normally impossible to hear. The app can also analyze any imported audio file into a spectrogram context.

ultrasonic1Ultrasonic is a great tool for doing bearing lubrication testing and detecting air leaks. The ultrasonic sensor plugs directly into the iPad’s Lightning port. It is a highly directional sensor enabling very precise readings.

This application takes full advantage of the iPad’s processor. For maximum resolution an iPad Air or Air 2 is required; the app utilizes the newer iPad’s 64-bit processor.
