Electromagnetic point level switch ELS-G12-M5-RS

Electromagnetic point level switch ELS-G12-M5-RS

The ELS electromagnetic point (High-Frequency) level switch is designed to detect the presence of the medium at its installation point through direct contact with the sensing element.
The sensor can be installed:
   — in metal tanks for level detection,
   — on pipes for pump dry-run protection.

A hygienic process connection with a conical seal makes the device suitable for food and pharmaceutical applications.

  • Process connection: E-G12 (G12)
  • Electrical connection: M12 5-pin connector (M5)
  • Options: RS-485 (Modbus RTU) (RS)
  • Features of the ELS point level switches
    • Advanced signal processing ensures stable operation even with challenging media, such as alkaline and acid solutions, liquid soap, and surfactants.
    • Automatic temperature compensation guarantees operational stability across the entire temperature range.
    • CIP/SIP compatible — the sensor can be cleaned at temperatures up to +120 °C for 1 hour.
    • Integration with ELHART Configurator simplifies commissioning, calibration, parameter transfer, and backup.
    • Full parameter configuration via the RS-485 (Modbus RTU) digital interface: setpoint, hysteresis, operating mode, and output type.
    • Real-time diagnostics: ability to read the current signal response to monitor sensor condition and adjust settings without removal.
    • Hygienic process connection without extra seals when using WA.22 or WA.24 adapters.
    • Fully encapsulated electronics protect against condensation and improve vibration resistance. Ingress protection is IP66/IP67.
    • Compact housing for installation in tanks or pipes with limited space.
    • Flexible output configuration: default state NO (normally open) or NC (normally closed); output type PNP, NPN, or Push-Pull.
