LQT3051WL module
Product Overview
The LQT3051WL wireless transmitter features a high-definition FSTN segment LCD and is compatible with up to ten different types of thermocouples, RTDs, and diffusion silicon sensors for temperature, pressure, and liquid level measurement. This product utilizes a 24-bit Σ-Δ analog front end to ensure high measurement accuracy. Comprehensive surge protection, lightning protection, and reverse polarity protection are incorporated, preventing misinstallation and mishandling in engineering applications. Enhanced software safety design includes features such as low-voltage monitoring reset and multi-task scheduling optimization. The LORA (Sub 1GHz) wireless communication offers long transmission distance and fast networking speed. The LQT3051WL is built entirely with industrial-grade components, ensuring a long service life and stable performance.
