EarthAlert

EarthAlert is an advanced grounding monitoring system designed to continuously monitor and display resistance levels in bonding and grounding connections, ensuring a reliable, low-resistance electrical path between the connected objects and earth.

Equipped with the innovative Road Tanker Recognition (RTR) feature, EarthAlert enhances safety and operational reliability during road tanker loading and unloading operations. The RTR functionality verifies that the grounding clamps are connected to a road tanker rather than an unintended grounded structure, such as an earthed pipe or metal frame, before permitting the transfer operation to commence.

EarthAlert incorporates an intelligent interlocking mechanism that prevents product transfer unless the required grounding protection is established and verified. By combining continuous resistance monitoring with road tanker identification, the system provides an additional layer of safety against incorrect grounding connections and helps mitigate the risks associated with electrostatic charge accumulation.

Application

EarthAlert is designed for industrial applications where electrostatic charge accumulation during material handling and transfer operations can create significant fire and explosion hazards. By monitoring grounding conditions and helping ensure effective static charge dissipation, EarthAlert enhances operational safety across a wide range of industries.

Key application areas include:

  • Petroleum and Petrochemical Industries: Loading and unloading of flammable liquids, including fuels and solvents, where effective grounding is essential for electrostatic hazard prevention.
  • Chemical and Paint Industries: Solvent unloading and the transfer of flammable liquids during processing and storage operations.
  • Pharmaceutical Industries: Milling, grinding, powder processing, and container-filling operations involving materials susceptible to electrostatic charge accumulation.
  • Food and Beverage Industries: Handling, milling, grinding, and filling of combustible powders, including sugar and wheat flour.
  • Fuel Transfer Operations: Refuelling of diesel generator sets and the transfer of fuels such as diesel and kerosene, as well as LPG handling applications, subject to the applicable system and installation requirements.
  • Terminal Automation: Monitoring grounding conditions of road tankers and rail wagons during loading and unloading operations, helping ensure that the required grounding protection is maintained throughout product transfer.

EarthAlert provides an additional layer of protection by monitoring grounding integrity and supporting interlocked control of transfer operations. It helps reduce the risk of electrostatic ignition, contributing to safer and more reliable industrial operations.

Features

  • Road Tanker Recognition (RTR): Verifies that the grounding clamps are connected through a road tanker rather than a fixed grounded structure, helping prevent incorrect connections and enhancing operational safety.
  • Real-Time Resistance Monitoring: Continuously monitors and displays grounding resistance values for both channels, along with capacitance status, enabling effective assessment of grounding conditions.
  • Grounding Interlock Protection: Prevents loading or unloading operations unless the required grounding conditions are established, helping mitigate electrostatic hazards.
  • Remote Monitoring and Communication: Transmits grounding status to a remote computer through the built-in serial port using the Modbus RTU protocol, facilitating integration with plant control and monitoring systems.
  • Rugged Vehicle Connection: Provides convenient and reliable connection to road tankers through a rugged plug-and-socket arrangement with a spiral cable, designed for practical industrial use.
  • Grounding Loop Resistance Detection: Detects resistance in the grounding loop to help verify the integrity of the grounding connection and ensure a reliable, low-resistance path to earth.
