Description

The Linshang LS213 ultrasonic wall thickness gauge measures materials that transmit ultrasound, including suitable metals, glass, ceramics and plastics. The standard 5 MHz dual-element probe covers 0.8–350 mm on 45# steel, with 0.01 mm resolution up to 100 mm and 0.1 mm resolution above that band.

Wall thickness checks with a standard probe

Use the LS213 with the standard probe for accessible pipe and plate locations that meet the probe’s measuring-area and geometry limits. The minimum pipe dimensions in the specification are for 45# steel; they are not universal limits for every material.

Set the appropriate sound velocity before testing. A known-thickness sample of the same material can be used to establish the velocity instead of relying on a generic preset. Apply couplant and hold the probe still with its full contact face supported. The opposite surface must be parallel or coaxial with the measuring surface.

Coatings and alternative probes

With the standard probe, E-E mode uses successive back-wall echoes to measure the substrate beneath a coating. Its stated limits are 0.2–2.5 mm coating thickness and 4–60 mm substrate thickness on 45# steel. Enable E-E mode for that application; the full normal measuring range does not apply in this mode. It reports substrate thickness rather than a separate coating thickness.

The LS213 also supports micro-diameter, coarse-crystal and high-temperature probes. The 7 MHz PT-06 covers 0.75–80 mm on 45# steel, while 2 MHz ZT-12 and 5 MHz GT-12 cover 3–200 mm. Choose the probe to match the material, access and measuring conditions; these probes do not share the standard probe’s full range.

Record results and compare locations

Bluetooth connects the gauge to the UT and HL app for Android 7.0 or later. Dedicated PC software supports measurement data handling and export. The instrument can store up to 999 readings; statistics mode shows maximum, minimum and average values, while QC mode compares readings with user-set limits.

Automatic gain adapts signal amplification to the workpiece. Use the built-in reference block for calibration, and keep the probe and block clean. The displayed increment is not the same as measurement accuracy; probe type, material velocity and coupling all matter when interpreting readings.
