UE Systems Ultraprobe 201 Grease Caddy

The UE Systems Ultraprobe 201 Grease Caddy lets one person lubricate a bearing and monitor its ultrasound at the same time. It mounts on a cartridge grease gun, converts bearing noise to a sound the technician hears in a headset, and lights a ten-segment bar so the grease can be stopped before the bearing is over-filled.

A simple ultrasound caddy for grease guns

The 201 is the straightforward member of the grease caddy range: there is a sensitivity dial, a red LED bar and headphones, and the brochure lists no menus or data memory. As lubricant levels fall, friction rises and produces ultrasonic waves that are directional and localised. The caddy focuses on those waves, even in a noisy plant, and the user listens for the point at which the sound settles.

UE Systems says the aim is to prevent over-lubrication, extend equipment life, save working hours and cut operating costs.

Technical specifications

Choosing between the 201 and the 401

If you need only a live indication while greasing, the 201 is enough. The 401 adds a digital dB display, 400 storage locations, route upload and download and trending through Ultratrend; the 201 has none of these. The 201 is lighter in the hand at 0.45 kg and runs on a nickel metal hydride pack, while the 401 uses lithium polymer.

A mounting kit is included, and the caddy has a magnetically mounted transducer, a swivel base for awkward angles and a front-end lamp. Heavy-duty headphones are provided for noisy areas. The brochure states a one-year manufacturer warranty, extended to five years once the registration card is completed; actual terms are confirmed in the quotation.

Because ultrasound is localised, the user should place the transducer on the bearing housing as close to the bearing as possible and keep the same contact point at each visit, so that readings can be compared from one route to the next. Hearing the sound also helps separate a lubrication problem from rubbing or impact noise.
