Company Profile
Product Details
The YDW3051 Intelligent Wireless Differential Pressure Transmitter is a high-precision, low-power industrial instrument designed for remote monitoring and data transmission. It integrates an industrial-grade MCU and a high-quality monocrystalline silicon sensor, ensuring accurate and stable measurement of liquids, gases, and steam. With built-in 4G CAT1 communication (via China Telecom’s network), it supports real-time data transmission to cloud platforms, making it ideal for IoT-based industrial applications. The device also features a local LCD/OLED display, explosion-proof housing, and robust protection against harsh environments.
Key Features
Advanced Sensor Technology: Uses monocrystalline silicon sensor with multi-point temperature compensation.
High Precision: Up to 0.075% accuracy with 24-bit ADC.
Wireless Communication: Supports 4G CAT1, LoRa, and other ISM bands (433/868/915 MHz).
Dual Alarm Modes: Timed transmission and value-based alarm triggering.
Explosion-Proof & Rugged: Rated Exd IICT6 / Exia IICT4 and IP67.
Wide Operating Range: -40°C to 85°C ambient temperature; -40°C to 120°C medium temperature.
