level transmitter circuit
LQL3051WL LoRa Wireless Board
LQL3051WL
Product Overview
The LQL3051WL wireless liquid level transmitter adopts an FSTN high-definition segment LCD, suitable for liquid level signals measured by reed switch sensors. This product uses a 24-bit Σ-Δ analog front end to ensure high measurement accuracy; comprehensive surge, lightning, and reverse polarity protection prevent misinstallation and misoperation in engineering applications; enhanced software safety design includes low-voltage monitoring reset, multi-task scheduling optimization, and other features. LORA (Sub 1GHz) wireless communication offers long transmission distances and fast networking speeds. The LQL3051WL is entirely built with industrial-grade components, ensuring long service life and stability.
