Integrated LCD Display with Wireless Remote Monitoring
The HM200E is a wireless digital pressure gauge combining an integrated LCD display with LoRa long-range wireless communication and cloud-based monitoring. It delivers the best of both worlds: a large, clear local display for field technicians to read pressure at the installation point, plus automatic wireless data transmission to a centralized cloud platform for real-time remote monitoring.
Unlike traditional analog pressure gauges that require separate electronic transmitters, the HM200E integrates digital pressure measurement, display, and wireless communication into a single device. This eliminates the need for both local digital gauges and remote transmitters, reducing hardware count and installation complexity while improving accuracy and enabling data-driven maintenance.
With configurable measuring ranges from 0–1 MPa to 0–100 MPa, the HM200E covers a broad spectrum of industrial pressure applications including water distribution, oil and gas wellheads, HVAC systems, compressed air networks, and fire suppression systems. The single crystal silicon sensing element delivers ±0.1% FS accuracy with exceptional long-term stability (≤0.1% FS/year), while the built-in lithium battery supports 3–5 years of autonomous operation even with the LCD display active.

Application Scenarios
The HM200E wireless digital pressure gauge is designed for applications requiring both local visual indication and remote wireless monitoring. The integrated LCD display eliminates the need for separate analog gauges while the LoRa wireless transmission enables centralized cloud-based pressure monitoring:
Remote Well & Pipeline Monitoring
Monitor wellhead pressure and pipeline conditions in oil & gas fields. LCD display provides visual field readings while LoRa transmits data to the cloud for centralized management.
Water Supply Network Pressure
Track distribution pressure across municipal water networks. Wireless installation eliminates trenching and cable costs, enabling rapid deployment across widespread infrastructure.
Industrial Gas & Compressed Air Systems
Monitor compressed air, nitrogen, and process gas pressures at multiple points. Cloud alerts notify operators of pressure drops indicating leaks or equipment issues.
HVAC System Pressure Monitoring
Track chiller, boiler, and hydronic system pressures in commercial buildings. Visual LCD gauge replaces analog gauges while adding wireless data collection capability.
Fire Suppression System Monitoring
Continuously monitor fire suppression system pressure to ensure readiness. Cloud platform provides 24/7 oversight with automatic alerts for pressure loss conditions.
Agricultural Irrigation Systems
Monitor pump discharge and pipeline pressure across irrigation networks. Battery-powered wireless sensors deploy quickly across large agricultural properties without infrastructure.
