Leeb252C

Coating Thickness Gauge

Magnetic Induction/eddy Current working principle, range 0~1500 μm, with three Measurement modes including high-precision measurement, with five statistics, support zero and one point calibrated.

Overview

 This instrument is a magnetic, eddy current integrated portable coating Thickness Gauge, which can quickly and non-damaging coating thickness measurement. It can be used both in the laboratory and in the engineering field. This instrument can be widely used in manufacturing, metal processing industry, chemical industry, commodity inspection and other testing fields, and is an important instrument for material protection.

Meets standards

• GB/T 4956-1985 Measurement of thickness of non-magnetic overlay on magnetic metal substrate -- Magnetic method

• GB/T 4957-1985 Thickness measurement of non-conductive overlay on non-magnetic metal substrates -- Eddy current method

• JB/T 8393-1996 Magnetic and eddy current cladding Thickness Gauge

• JJG 889-95 Magnetoresistive Thickness Gauge

• JJG 818-93

Features

• Two thickness measurement methods, magnetic and eddy current, are used to measure the thickness of the non-magnetic overlay on the magnetic metal substrate and the thickness of the non-conductive overlay on the non-magnetic metal matrix.

• There are two measurement methods: continuous measurement and single measurement

• It has three measurement modes：The high-precision measurement mode can average multiple measurements and automatically filter the suspicious data to ensure that the measured values are more accurate and stable. The fast measurement mode enables real-time scanning capabilities.

• It has a temperature compensation function：Real-time temperature compensation technology automatically compensates for measurement errors caused by changes in ambient temperature and probe temperature, making measurements more accurate.

• There are five statistics：MEAN (MEAN), MAXIMUM (MAX), MINIMUM (MIN), NUMBER OF TESTS (NO.), STANDARD DEVIATION (S.DEV).

• The instrument can be calibrated using zero, single- or two-point calibration, and systematic errors in the probe can be corrected using basic calibration and temperature coefficient calibration.

• It has a storage function：Up to 500 measured values can be stored.

• It has a delete function：Delete a single suspicious data that appears in a measurement, or delete all data in the store so that a new measurement can be made.

• Limits can be set：Automatic alarms for measured values outside the limits.

• It has the function of power level indication.

• There is a beep prompt during operation.

• It is said that there are three ways to shut down：Manual shutdown mode, timeout automatic shutdown mode and low-battery automatic shutdown mode, and the waiting time for timeout automatic shutdown can be set.

Description

Principle

• This instrument adopts two thickness measurement methods, magnetic and eddy current, which can measure the thickness of the non-magnetic covering layer (such as aluminum, chromium, copper, enamel, rubber, paint, etc.) on the magnetic metal matrix (such as iron, cobalt, nickel) and the thickness of the non-conductive covering layer (such as enamel, rubber, paint, plastic, etc.) on the 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 overlay, the probe and the magnetic metal substrate form a closed magnetic circuit, due to the presence of the non-magnetic overlay, the magnetic circuit reluctance changes, and the thickness of the overlay can be measured by the change of its magnetic resistance.

A. Eddy current method (N-type probe):

The high-frequency alternating current is used to generate an electromagnetic field in the coil, and when the probe is in contact with the overlay, eddy currents are generated on the metal substrate, and feedback is generated on the coils in the probe, and the thickness of the overlay can be derived by measuring the magnitude of the feedback action.
