Description

Overview
  • LoRaWAN® pipe pressure sensor EM500-PP for continuous monitoring of liquid and gas pipeline pressure to detect anomalies and help prevent pipe failure and major bursts.


Key benefits
  • Suitable for various pipe systems (liquids and gases) across industrial applications.
  • High measuring accuracy to detect small pressure variations (±0.5% FS).
  • Designed for shock, vibration and corrosion resistance to operate in harsh environments.
  • Wireless LoRaWAN® transmission for secure, wide-coverage deployment.
  • Ultra-low power design with 1 × 19000 mAh ER34615 internal battery (typ. up to 10 years under typical conditions).


Wireless & Cloud
  • LoRaWAN® device compatible with standard gateways and network servers; multi-region frequency options available.
  • Integration with Milesight IoT Cloud for dashboards, automatic triggers, reports and real-time alerts; Android & iOS app support for remote management.


Configuration & Operation
  • Easy NFC configuration via mobile phone or PC using Milesight ToolBox; additional configuration via internal USB Type-C and downlink.
  • Local indicators and controls: 1 × internal LED; 1 × internal power/reset button.


Installation
  • Flexible mounting: pole, wall or DIN-rail options.
  • Sensor cable: 1.5 m attached cable; process connection G 1/2" (male) for straightforward pipe integration.


Cloud & Edge Features
  • Local data storage and retransmission, configurable threshold alarms and compatibility with Milesight D2D controller.
  • Data visualization dashboard, scene-based automation and device management via Milesight IoT Cloud.
