Low-temperature multi-point thickness measurement system
Using a dual-crystal multi-probe system and leveraging the pulse-echo measurement principle, this device enables multi-point thickness measurement. With one instrument supporting multiple probes, users can specify particular locations, define grid-like or array-based measurement layouts across designated areas, and monitor wall thicknesses at multiple points in real time online. The probes are securely and permanently installed using a triple-fixation method—bonding coupling, magnetic clamping, and clamp locking. The system transmits data via both wired and wireless communication channels. It supports various power supply options, including rechargeable batteries, DC power sources, and solar energy, making it suitable for a wide range of application scenarios.
