LUP Series compact Leak Detect Sensor

The Compact LUP Liquid Detection Sensor is an exceptionally low-profile leak detector that identifies water, chemicals, and other industrial liquids. These units are typically placed in a drip pan or similar location to monitor for leaks. If they end up in the thinnest pool of liquid, they trigger an alarm. LUP Series liquid detection sensors use a detector looking at an LED; if that light path gets altered, it knows liquid is present. These liquid sensors can detect virtually any industrial liquid as long as it is not exposed to excessively high or low temperatures.

*Note: These liquid detection sensor units are not rated to operate in a hazardous, potentially explosive environment or to detect flammable liquids.

Features of the Compact LUP Series Liquid Detection Sensors

The Compact LUP Series Liquid Detection Sensor is manufactured with a polypropylene body and a vinyl chloride cable. These materials provide excellent resistance to corrosive chemicals. Despite its ultra-small size of just 24 mm in diameter, LUP Series sensors feature a built-in amplifier with a 50 mA output and an LED light that remains green when no liquid is present and turns red when liquid is detected.

The low-profile design of the LUP Series Liquid Detection Sensors makes it a versatile solution for liquid monitoring in tight spaces. Measuring a diameter of φ24 and height of 17.2mm, it can fit in nearly any location requiring liquid monitoring. These liquid sensors are also highly cost-effective, providing fast and reliable liquid detection at low price points.

Benefits of the LUP Series Liquid Detection Sensors

• Exceptionally compact design, ideal for use in applications with limited space
• Reliable performance and fast response time when detecting liquids
• Cost-effective
• Compatibility with many liquids in industrial settings, including water, chemicals, and more
• Polypropylene housing and vinyl chloride cable can withstand exposure to harsh chemicals

Industrial Applications for Compact LUP Liquid Detectors

Because the LUP Series Liquid Detection Sensors feature a very small, compact design, they are typically used in industrial applications where space is limited. This includes food and beverage processing equipment, water treatment facilities, OEM production lines, chemical processing equipment, and more.
