HM200J Solar Wireless Pressure Transmitter

Product Overview

The HM200J Solar Wireless Pressure Transmitter represents the next generation of autonomous pressure monitoring for challenging outdoor environments. This solar-powered variant combines proven pressure measurement accuracy with self-sustaining renewable energy, eliminating the need for external charging infrastructure or battery replacement in remote deployments.

With an ultra-wide pressure range of -0.1 to 500 MPa and high accuracy specifications (±0.5% to ±0.1% FS), the HM200J delivers reliable data across diverse applications. The integrated 20Ah rechargeable lithium battery combined with high-efficiency 50W solar panel technology provides indefinite operational autonomy in outdoor installations. Multi-protocol wireless support (4G, LoRa, WiFi, Zigbee, LoRaWAN) ensures flexible connectivity regardless of available infrastructure.

Designed for critical infrastructure monitoring in natural gas pipelines, city heating networks, and oilfield operations, the HM200J features 316L stainless steel construction for corrosive media compatibility. IP67 standard protection (optional IP68) and optional ATEX explosion-proof certification (Ex db IIC T6) ensure reliable performance in the most demanding outdoor and hazardous environments.

Frequently Asked Questions

The HM200J’s dual-stage charging system and 20Ah battery provide energy storage for operation during cloudy periods and reduced sunlight. In temperate climates, the 50W panel charges during good weather, storing energy for lower-light periods. A high-power 100W panel option is available for regions with limited sunlight or high latitude installations.

In typical outdoor installations with adequate sunlight, the 20Ah battery operates for 5-7 years before noticeable degradation. Since the HM200J is continuously solar-recharged, the battery experiences fewer deep discharge cycles than battery-only devices. Tool-free field replacement is straightforward — contact our team for replacement battery kits.

While designed for sunlit installations, partial shade tolerance depends on the degree of shading and local sun angles. 2-4 hours of direct daily sunlight typically sustains operation. For heavily shaded locations, consider the high-power 100W solar panel option or hybrid 4G backup connectivity for continuous operation.

Yes. The high-efficiency solar panel is user-replaceable with standard tools. Periodic cleaning (2-4 times yearly) with soft cloth and deionized water maintains optimal output. Dust and debris accumulation reduces charging efficiency. Replacement panels are available as spare parts for extended service life.

The HM200J transmits data via your chosen wireless protocol (4G, LoRa, etc.) to native cloud platforms including Azure IoT, AWS IoT, and Alibaba Cloud. Real-time dashboards display pressure data, battery charge status, and solar panel output. Configurable reporting intervals (1s-3600s) let you balance data granularity with power consumption.

The HM200J supports standard G1/4, G1/2, M20x1.5, and NPT thread connections. Mounting options include pole-mount brackets for pipeline installations, wall-mount plates for facility monitoring, and ground-mount stands for wellhead applications. Custom process connections are available for OEM orders.
