This product is primarily suitable for online pressure monitoring systems in low-oil equipment, enabling real-time monitoring of oil pressure, wireless transmission and display of temperature data, as well as analysis and alarm functions. The implementation plan for pressure and temperature monitoring involves installing wireless pressure and temperature online monitoring devices at grounding sampling ports.

Wireless Battery Power Supply: The battery capacity is 19,000 mAh, ensuring a minimum of six years of use before replacement. (Battery replacement: Manually unscrew the housing, unplug the power connector, and insert a new battery. Data will not be lost during replacement. Our company provides two free battery replacements.)

Wireless Solar Power Supply: Equipped with an internal supercapacitor, ensuring continuous operation for over 30 days without sunlight.
