The UE Systems Ultraprobe 201 grease caddy is designed to attach to most standard grease guns to help lubrication technicians simultaneously lubricate and monitor ultrasound levels to prevent overlubrication of operating equipment.

The short wave, high frequency nature of ultrasound offers many advantages for instruments used to inspect equipment. The amplitude of generated ultrasounds will fall off rapidly as the sound travels from its source, providing a localized signal that can be detected and monitored with relative ease in most noisy environments. The subtle nature of this signal provides for early warning of potential failure modes.

Increases in friction of rolling elements can be detected and used as an indication of low lubrication levels. Using baseline information, amplitude levels can be used as a guide for determining when and when not to lubricate a bearing. The 201 grease caddy uses an electronic process called heterodyning to allow for accurate translation of ultrasound produced by operating equipment into the audible range. Users can hear these sounds through headphones and observe the amplitude of the sound on a meter. The heterodyned signal helps users hear when grease is entering the bearing and recognize when to stop lubricating.
