Overview
The Inventory Master’s LoRaWAN Explosion-Proof Digital Pressure Gauge is a battery-powered, low-power device with wireless digital output. It supports 4G, LoRa-IoT, and NB-IoT communication, featuring a built-in laser-welded pressure sensor for high accuracy and long-term stability. With an LCD display, MCU, and low-power design, it wirelessly transmits real-time pipeline pressure to the cloud. Made with 304 joints and a cast aluminum housing, it is explosion-proof and shock-resistant. Suitable for gas, liquid, and oil, it offers an adjustable upload rate from 1 minute to 24 hours.
Features
- Bluetooth configuration
- Built-in MCU
- Low power consumption design
- Explosion proof certification
