Why Choose the Carlo Gavazzi ILSP3MS5 Magnetic Level Sensor?

The Carlo Gavazzi ILSP3MS5, manufacturer reference 14516048 and also identified as ILSP.3M/S5, is a compact magnetic liquid level sensor with float designed for dependable liquid-level detection in tanks, reservoirs and industrial fluid-handling equipment. Part of the Carlo Gavazzi ILSP series, it uses a magnetic float and reed-contact principle to provide straightforward level switching.

The ILSP3MS5 features a compact Ø25 mm cylindrical float and an M18 × 1.5 mounting thread. Its plastic construction provides a lightweight solution for compatible liquids, while the compact float dimensions make the sensor suitable for applications where installation space inside the vessel is limited.

The sensor provides a normally-open (NO) output and is rated for a maximum switching voltage of 250 V AC and switching current of 3 A. Electrical connection is provided through a 0.5 m cable, allowing straightforward integration into compatible level-monitoring, alarm and industrial control circuits.

Key Advantages

  • Reliable magnetic liquid-level detection using float-operated reed-switch technology.
  • Compact Ø25 mm float for installations with restricted space.
  • Normally-open (NO) switching output for compatible control and alarm circuits.
  • Maximum switching voltage of 250 V AC.
  • Maximum switching current of 3 A.
  • 0.5 m cable provides a straightforward electrical connection.
  • M18 × 1.5 threaded mounting simplifies installation in suitable tanks and vessels.
  • Simple magnetic operating principle provides dependable level switching with minimal complexity.

Key Features

  • Carlo Gavazzi ILSP series magnetic level sensor.
  • Manufacturer reference 14516048.
  • Alternative designation ILSP.3M/S5.
  • Magnetic float and reed-contact sensing principle.
  • Normally-open (NO) output.
  • Ø25 mm cylindrical float.
  • M18 × 1.5 mounting thread.
  • Maximum switching voltage: 250 V AC.
  • Maximum switching current: 3 A.
  • 0.5 m cable connection.
  • Plastic sensor construction.
  • Compact design for tank and reservoir installations.
  • Suitable for liquid-level switching and monitoring.

Reliable Magnetic Liquid-Level Monitoring

Magnetic level sensors detect changes in liquid level through the movement of a float containing a magnet. When the float reaches its switching position, the magnetic field operates the internal reed contact, providing a simple electrical signal without requiring complex electronic sensing circuitry.

The ILSP3MS5 combines this proven sensing principle with a compact Ø25 mm float and M18 × 1.5 mounting arrangement. Its normally-open contact can be incorporated into suitable alarm, control and monitoring circuits for applications requiring dependable indication when liquid reaches a predetermined level.

Typical Applications

  • Industrial tank liquid-level monitoring.
  • Storage vessels and reservoirs.
  • High- or low-level indication systems.
  • Pump and fluid-management systems.
  • Machine coolant reservoirs.
  • Process and manufacturing equipment.
  • Industrial automation systems.
  • Liquid presence and level-control applications.
