This series of Wireless Digital Pressure Gauges is an industrial-grade, low-power pressure monitoring instrument engineered for real-time pipeline pressure acquisition and cloud telemetry. Built with a rugged explosion-proof alloy aluminum housing, 304 stainless steel connectors, and a 76mm full-screen LCD display, it delivers high-precision measurements with exceptional long-term stability. Featuring integrated MCU processing and versatile 4G, NB-IoT, or LoRa cellular connectivity, it provides an end-to-end smart metering solution for oil, water, and gas pipelines.

Key Features & Highlights

• Multiple Network Transmission & Smart Configuration: Supports 4G, NB-IoT, and LoRa wireless networks with customizable IP address settings. Parameters including sampling rate, report frequency, and alarm limits can be configured via local Bluetooth or remotely through the platform.

• Comprehensive Pressure Ranges & High Precision: Offers wide measurement capabilities across standard pressure (0-1.6...60 MPa), micro pressure (0-1...1000 kPa), and vacuum/compound pressure (-100...1000 kPa) with 0.5% FS accuracy class.

• Intelligent Alarm & Asset Safety System: Features customizable full-range high/low pressure threshold alarms, pressure fluctuation alarms, low battery alerts, and GPS location tracking to ensure operational safety.

• Ultra-Low Power & Dual Power Options: Powered by an internal 3.6V high-capacity lithium battery with ultra-low power consumption, or optionally wired via 12V/24V DC external power.

• Heavy-Duty Industrial Design: Encased in an explosion-proof alloy aluminum body with 304 stainless steel process connections. Equipped with anti-electromagnetic interference protection and broad operating temperature endurance (-40°C to 80°C).
