Product Overview

Nexisense YD-221WL LoRa wireless pressure transmitter is an intelligent wireless instrument specifically developed for remote pressure monitoring in industrial sites. It merges high-precision diffused silicon sensing technology with LoRa low-power wide-area network (LPWAN) communication technology to transmit on-site pressure signals to cloud platforms or local monitoring systems in a real-time and stable manner.

The product features an industrial-grade explosion-proof housing design with a clear and intuitive local LCD display, supporting multiple communication methods (LoRa standard configuration, optional NB-IoT/4G Cat1). Built-in high-capacity lithium battery, coupled with ultra-low power consumption design, significantly extends equipment battery life, truly achieving a "zero wiring, zero power supply, zero maintenance" deployment experience, making it an ideal upgrade replacement for traditional wired pressure transmitters.

Core Technical Advantages

1. High-precision Diffused Silicon Core and Temperature Compensation Adopting high-performance diffused silicon cores, with an accuracy grade of 0.5%FS (customizable 0.1%, 0.25% high precision). Supports 4-point temperature compensation according to customer needs, effectively eliminating the impact of temperature changes on pressure measurement and ensuring high precision and long-term stability across a wide temperature range.

2. LoRa Long-distance Low-power Wireless Transmission Centered on LoRa ad-hoc networking, the urban transmission distance can reach 2-5km, supporting ISM bands (433/868/915MHz). Low-power design combined with high-capacity lithium batteries results in an average communication current of only 100mA@3.6VDC and a standby current as low as 20uA@3.6VDC, greatly extending equipment battery life.

3. Industrial-grade Explosion-proof and Strong Anti-interference Ability Complies with Exdb IIC T6 Gb explosion-proof standards, utilizing high-protection ABS materials and stainless steel processes with an IP67 protection rating. Supports reverse polarity protection, current-limiting protection, lightning resistance, and impact resistance, adapting to harsh industrial environments such as vibration, moisture, and dust.

4. Intelligent Cloud Platform and Flexible Integration The free cloud platform provides 24/7 all-weather monitoring, supporting multi-person hierarchical authority management, data storage, and historical queries. Automatic SMS/phone alarms can be set for pressure over-limits, and it supports data reporting via multiple protocols like TCP/UDP, easily integrating into existing SCADA, PLC, or IoT platforms.
