Why Choose the Carlo Gavazzi ILMM5/S2/AT Magnetic Level Sensor?

The Carlo Gavazzi ILMM5/S2/AT is a high-temperature stainless-steel magnetic float level sensor designed for reliable point-level detection of liquids in demanding industrial tanks, vessels and process equipment. Part of the Carlo Gavazzi ILMM series, it combines a magnetic float with a dry reed contact to provide straightforward and dependable liquid level switching without requiring complex sensing electronics.

This specialised high-temperature version features an AISI 316 stainless-steel float and housing with a normally closed (NC) reed contact. Its robust construction makes it particularly suitable for corrosive environments and demanding applications in the food, chemical and oil industries where reliable liquid level monitoring is required.

The ILMM5/S2/AT supports a maximum switching voltage of 240 V AC / 220 V DC, maximum switching current of 0.5 A and maximum switching power of 50 VA. A factory-fitted 0.3 m Teflon cable, IP68 sensor protection and an extended operating temperature range of -10 to +200 °C make it especially suitable for high-temperature industrial liquid-level applications.

Reliable High-Temperature Magnetic Float Level Detection

Magnetic float level sensors such as the Carlo Gavazzi ILMM5/S2/AT use the movement of a float to actuate an internal reed contact. As the liquid level rises or falls, the float follows the liquid surface and its internal magnet changes the state of the reed contact at the defined switching position, providing a simple and dependable electrical indication of liquid level.

The ILMM5/S2/AT is specifically designed for applications requiring greater temperature resistance than standard ILMM variants. Its -10 to +200 °C operating range, AISI 316 stainless-steel construction and Teflon cable make it well suited to high-temperature and corrosive process environments, including food production, chemical processing and oil handling systems.

Typical Applications

• High-temperature industrial tank level monitoring.
• High- and low-level liquid detection.
• Food processing and production equipment.
• Chemical processing and storage systems.
• Oil and lubricant tanks.
• Corrosive liquid handling applications.
• Process vessels and reservoirs.
• Industrial filling, emptying and pump control systems.
