Overview:

Best Suited For:
  • Chemical/Petrochemical (excl. Oil & Gas)
  • Nuclear Power
  • Oil and Gas
  • Power Generation
  • Power/Gas Transmission and Distribution

The ELS2 Electrolyte Level Sensor is a non-invasive level sensor with incorporated temperature monitoring designed for quick installation and easy set up. This system complies with the NERC PRC-005 requirements for electrolyte level inspection. With this sensor, you eliminate unnecessary remote site visits and will eliminate the required quarterly inspection of battery electrolyte level in your battery string.

An ELS2 system will include one sensor module to be attached to each cell for monitoring electrolyte level and temperature. Each of these modules will be connected back to a system interface module called the ELSI2 for processing of data for alarm analysis and reporting. The system can operate as a standalone or when combined with the Alber UXIME, provides all battery monitoring features.

System Advantages and Features

  • Three form C contacts for alarm notification: Level alarm, temperature alarm and hardware alarm. Features also a RS-485 interface with Modbus protocol and a USB style B interface
  • Alarms for low and critical low electrolyte levels, cell temperature, sensor attachment failure and hardware malfunction
  • Status indicators on each cell for easy alarm identification
  • Automatic or manual reset for any alarm
  • Designed to work on nonopaque VLA battery cases
  • Automatic calibration, remote alarm reset and quick firmware upgrades
  • Easily integrates into Albér Battery Monitors or building management systems
  • Engineered for quick installation and easy system setup
