The UHZ-DY level transmitter adopts a four-digit digital tube display, significantly reducing costs compared to traditional transmitters with digital displays. This transmitter is suitable for resistance-type level sensors such as magnetic flap and float ball types. The UHZ utilizes a 24-bit Σ-Δ analog front end, offering both anti-interference and high-precision characteristics. It features comprehensive surge protection, lightning strike protection, and reverse connection protection designs, preventing misinstallation and misoperation in engineering applications. Enhanced software security design includes low-voltage monitoring reset and multi-task scheduling optimization. All components of the UHZ are imported, ensuring long service life and stability.
