LQP3051H HART Board
Product Overview
The LQP3051H is suitable for diffused silicon pressure sensors, supports HART protocol communication and 4-20mA transmission, and features anti-interference and high stability. It uses an industrial-grade 24-bit independent Σ-Δ analog-to-digital conversion chip to ensure measurement accuracy. Comprehensive surge protection and reverse polarity protection design prevent installation errors and operational mistakes in engineering applications. Enhanced software safety design includes low-voltage monitoring reset, multi-task scheduling optimization, and other features. All components are industrial-grade, ensuring a long service life and adaptability to complex operating environments. While delivering excellent performance, this product also offers rich functionality. Users can configure parameters using the buttons on the instrument or HART communication devices (PC-based host software or handheld communicator).
