CAMLogic Float Level Indicator PFGLP22 Series

Introduction – CAMLogic Float Level Indicator PFGLP22 Series

The CAMLogic Float Level Indicator PFGLP22 Series is a robust and reliable solution for liquid level detection, operating entirely on the principle of buoyancy. As the liquid level changes, the float moves accordingly, and this motion is magnetically transmitted to an internal microswitch that generates a switching signal — all without requiring any external power supply.

Built with high-grade stainless steel (AISI 316) and a powder-coated aluminium housing, the PFGLP22 ensures long-term durability even in corrosive or hygienic environments. The hermetically sealed structure separates the float chamber from the electrical components, ensuring complete process isolation and maximum safety.

This float level switch is designed for side or top mounting in tanks or vessels and can operate under process pressures up to 25 bar and temperatures from –10 °C to +100 °C. With ATEX certification (Zone 22), it is suitable for installations where explosive dusts or powders may be present.

Engineered for industrial reliability and simplicity, the CAMLogic PFGLP22 combines mechanical precision, food compliance (EC 1935/2004), and maintenance-free operation, making it an ideal choice for industries in the UAE and across the MENA region seeking dependable level monitoring solutions from Dubai Sensor.
