Ultrasonic Thickness Online (Small Tube)

The SL-Ultrascan series applies the same ultrasonic principle to small-diameter tube, with an original auto-adjusting structure that lets the probe self-centre and follow — wall 0.18–10mm, diameter 2–50mm.

What is it

What the small-tube gauge is

The SL-Ultrascan series is a dedicated product for on-line thickness measurement of small-diameter pipes and cables, applying the same ultrasonic principle to measure OD, thickness, eccentricity and ovality in real time, with data storage and report generation.

Suitable for medical catheters, wires and cables, pipes and automotive oil pipes. It measures wall thickness of 0.18–10mm across a 2–50mm diameter range. Its original auto-adjusting structure automatically adapts to different pipe sizes, and the probe centres and follows on-line, ensuring accurate, efficient and stable detection.

Application

Where it is used

Medical catheter, cable, small-bore tubing and automotive oil pipe — extrusion lines where the bore is narrow and wall and geometry have to be exact.

Software

Software & data capability

The same Sealion ultrasonic software as the large-pipe system, turning readings into production data you can query, export and trace.

Live readings Wall thickness per probe, plus mean, maximum and minimum wall with the position of the thickest and thinnest points; mean, max and min outer and inner diameter; eccentricity and ovality shown live.

Live curves Thickness and outer-diameter curves are plotted in real time against the recipe's upper and lower limits.

Recipe management A full set of measuring parameters is stored per spec and recalled on changeover; recipes can be added, edited, searched, deleted and read back.

Alarm tracking Alarm items and deviations are user-set; breaches are alarmed and logged, searchable by date range, with records kept for a year.

Query & export Configurable logging interval, query by date range, table or curve display, Excel export and one-click export to USB.

Remote monitoring Live data to a monitoring room over TCP/IP; the interface switches between Chinese and English.

Why Sealion

Ten reasons to choose Sealion ultrasonic

01 A dedicated R&D company — recognised as an Innovation Little Giant, a High-Tech Enterprise and a Specialised & Sophisticated (SRDI) enterprise

02 Sixteen years of independent ultrasonic R&D

03 China's first ultrasonic online thickness system with fully owned IP and copyright

04 A second-generation, in-house design with a 250MHz ultrasonic sampling rate — 50MHz higher than others on the market today

05 Core parts use a US semiconductor chip and a US Olympus ultrasonic probe with a 1-inch receiving diameter

06 APCI industrial panel PC with multiple data interfaces

07 Data can be saved and exported; product quality is traceable

08 Lifetime maintenance, two-year free warranty, free upgrades and free customisation — better value

09 Remote monitoring, order placement over WiFi, optional ERP integration

10 Fully in-house, so it can be tailored to each plant

The smaller the tube, the less room the wall has to be wrong

Small bores that won't measure, probes that won't centre, a re-setup at every size change — this is what we solve daily.
