LEEB Leeb232 Coating Thickness Gauge magnetic Induction/eddy Current Range 0~1250μm

Overview

Using two measurement methods of magnetic and eddy current, the thickness of the non-magnetic covering layer on the magnetic metal substrate (such as aluminum, chromium, copper, zinc, tin, rubber, paint, etc.) can be detected, and the thickness of the non-conductive insulating covering layer on the non-magnetic metal substrate (such as aluminum, copper, zinc, rubber on tin, plastic, paint, oxide film, etc.).

Coating Thickness Gauges are used in electroplating, anti-corrosion, aerospace, aviation, chemical industry, automobile, shipbuilding, light industry, commodity inspection and other testing fields. It can be used in both laboratories and engineering sites. Equipped with different probes, it is suitable for different occasions. It is an essential instrument in the testing industry.

Main function

● There are two measurement methods: continuous measurement and single measurement method;

● There are two Operating Modes: direct and group mode;

● With automatic statistics function: average value (MEAN), maximum value (MAX), minimum value (MIN), number of tests (NO.), standard deviation (S. DEV);

● The instrument can be calibrated by two methods: single-point calibration and two-point calibration, and the systematic error of the probe can be corrected by the basic calibration method;

● Storage function: 4 correction workpieces can be stored. 26 groups of each type, 15 in each group, with a total of 1560 measured values;

● Delete function: delete a single suspicious data that appears in the measurement, and also delete the data in the storage area for new measurements;

● Set the limit: the measured value outside the limit can be automatically alarmed;

● With power underVoltage indication function, there is a beep prompt during operation, and the automatic shutdown mode.

● Metal shell: The fuselage material is aviation aluminum metal shell, which has low anti-interference and wear.

Measurement principle

This instrument adopts the thickness measurement method of magnetic principle, which can measure the thickness of non-magnetic coating layer (such as aluminum, chromium, copper, enamel, rubber, paint, etc.) on magnetic metal matrix (such as iron, cobalt, nickel). The measurement principle of eddy current is also used to measure the thickness of non-conductive coating layer (such as enamel, rubber, paint, plastic, etc.) on non-magnetic metal matrix (such as copper, aluminum, zinc, tin, etc.).

A. Magnetic method (F-type probe): When the probe is in contact with the cover layer, the probe and the magnetic metal substrate form a closed magnetic circuit. Due to the existence of the non-magnetic cover layer, the magnetic circuit magnetoresistance changes. The thickness of the cover layer can be measured by the amount of change.

B. Eddy current method (N-type probe): use high-frequency alternating current to generate an electromagnetic field in the coil. When the probe is in contact with the cover layer, an eddy current is generated on the metal substrate, and the coil in the probe is generated. Feedback effect, the thickness of the covering layer can be derived by measuring the magnitude of the feedback effect.
