Portable Ultrasonic Thickness Gauge price SA40+ which can test thickness covered with coating

Introduction

SA40+ is the miniaturized ultrasonic thickness gauges that can measure wall thickness and velocity.

Using new technique of multiple echo(echo-to-echo), SA40+ can measure wall thickness under paint. For a normal ultrasonic thickness gauge, you must remove paint on work piece, but with new SA40+, you can take measurement directly over the paint of work piece and you can get real thickness value of work piece. SA40+ has two measuring modes: normal mode and multiple echo(MEC) mode. By normal mode, SA40+ is a normal ultrasonic thickness gauge; by MEC mode, SA40+ can measure over coatings.

1.Thermal Material Measuring

Materials thickness with maximum 400℃ surface temperature could be measured using high temperature probe GT-5. Precautions: when measuring thermal materials:

Apply high temperature couplant, measure immediately after the couplant melts, the probe contact shall be less than 10 seconds and the interval between two measurements shall be no less than 1 minute.

Prevent the probe from being vibrated; otherwise the probe will be damaged.

When the temperature of thermal material increases 100℃, the velocity decreases about 1%. Correction needs to be done to the measuring values.

E.g.: we can define δ0 as the actual thickness of the material, δt as the display value in the instrument

Then:

When 125℃, δ 0 =δ t×0.99

When 225℃, δ 0 =δ t×0.98

When 325℃, δ 0 =δ t×0.97

Also, when we know accurately the material temperature to be measured, we can also correct the velocity of the instrument.

For example: under normal temperature (25℃), velocity of the material =5900 m/s,

When 125℃, velocity ≈5840m/s

When 225℃, velocity ≈5780m/s

When 325℃, velocity ≈5720m/s

Then, the displayed value is the actual value of the material.
