level transmitter circuit
LQL2088 Digital Tube Display Board
LQL2088
Product Overview
This intelligent liquid level transmitter uses a four-digit digital tube display, which greatly reduces costs compared to traditional transmitters with digital displays, and is suitable for magnetoresistive sensors. It employs a 24-bit Σ-Δ analog front-end to ensure high measurement accuracy; comprehensive surge, lightning, and reverse polarity protection design prevents incorrect installation and operation in engineering applications; enhanced software safety design includes low-voltage monitoring reset, multi-task scheduling optimization, and other features. All industrial-grade components are used to ensure long service life and stability.
