1. New Product Introduction

TIME2520 coating thickness gauge is a new platform based deviceIntelligent coating thickness gaugeIt can be connected to a mobile phone through Bluetooth and has powerful functions through the Times Intelligence Detection APP. TIME2520 data display relies on the powerful functions of mobile apps to display measurement data more clearly. Various settings are easily visible on one interface, and powerful post-processing can also be achieved after measurement.

The intelligent sensor is built using a brand new platform and signal processing circuit, enabling it to achieve signal processing, signal digitization, work status prompt, data transmission and other functions in a limited space. At the same time, the application of digital technology in sensor signals has significantly improved its anti-interference ability compared to traditional analog signal transmission, resulting in more accurate and stable measurements.

At present, intelligent measuring heads can achieve automatic identification and measurement of iron and non-ferrous metals, with a measurement range of 0-1500 μ m for iron and 0-700 μ m for non-ferrous metals, which can meet the needs of the vast majority of scenarios.

2 Working principle

1) Magnetic principle

Suitable for measuring non-magnetic coatings on magnetic metal substrates; By using a closed magnetic circuit composed of a magnetic probe and a magnetic metal substrate, the presence of a non-magnetic cover layer can cause changes in the magnetic resistance of the circuit. The thickness of the cover layer can be calculated by measuring the changes in magnetic resistance.

2) Principle of eddy current

Suitable for measuring non-conductive coatings on non-magnetic metal substrates; When the high-frequency alternating current in the probe coil generates an electromagnetic field, eddy currents are generated on the metal substrate, and the thickness of the coating layer is derived by measuring the feedback effect of the eddy currents.
