Leak sensors for the early detection of water leaks

A leak sensor monitors areas where water leaks need to be detected as early as possible. It is used in locations where Humidity could interfere with electrical or electronic systems—for example, in utility rooms, under equipment, along pipes, or near condensate and water connections. As soon as water reaches the sensor, the connected switch contact can be used to trigger an alert or a downstream response.

The selection depends primarily on where water needs to be detected and how large the area to be monitored is. In this collection, you'll find leak sensors and water intrusion detectors with various sensor designs.

Which leak sensor is right for the application?

Spot Monitoring with a Surface Sensor

A surface sensor is appropriate when a specific location needs to be monitored—such as the floor beneath a piece of equipment, a drainage area, or a spot where water is likely to collect first. It is crucial that the sensor be positioned at the lowest or most critical point in the area.

Monitor larger areas with a flexible sensor rod

A flexible sensor cable is suitable when the potential leak point is not limited to a single location. It can be laid along a section to be monitored, such as near water-carrying pipes or systems. Select the appropriate length based on the actual length of the section to be covered and the local installation conditions.

Monitoring Water Pipes: Detecting Leaks Rather Than Pipe Pressure

Anyone looking for a leak sensor for a water line usually wants to detect water leaks in the vicinity of the line. To do this, the sensor is installed at potential leak points or along the section of the pipe to be monitored. A leak sensor is not a substitute for Pressure or flow monitoring of the pipe; therefore, check the specific application and installation location to ensure it provides the desired protection.

Here's what you should look for when making your selection

Installation Location: Specify where water should be detected first.
Monitoring Area: A surface sensor is suitable for specific spots; for longer sections, a flexible sensor rod may be a good choice.
Housing and Sensor Variants: Choose between internal and external sensor configurations depending on the installation situation.
Switching function: Check the requirements of the connected system as well as the desired alarm or shutdown.
Environmental Conditions: Take into account the protection rating, the installation method, and the conditions at the actual installation site.

The current product lineup includes models with changeover contacts/relays and an IP65 protection rating. The respective product page contains the official specifications for the specific model.

Overview of Available Models

The HYGRASREG® LS-2 and LS-4 models are designed for localized leak detection. The HYGRASREG® LS-Flex 3 m and LS-Flex 6 m variants extend monitoring capabilities to a flexible sensor rod. Before purchasing, compare the product details, the installation location, and the required length of the sensor run.

Frequently Asked Questions About Leak Sensors

Where is a leak sensor installed?

The sensor should be installed in the location where water would first accumulate or leak in the event of an incident. This could be under equipment, near water connections, in utility rooms, or along potential leak points. If a flexible sensor cable is used, it is also important to install it properly along the section to be monitored.

What is the difference between a surface sensor and a flexible sensor rod?

A surface sensor monitors a clearly defined point. A flexible sensor rod, on the other hand, covers a longer distance and may be useful in situations where water could leak from several possible locations. The appropriate option depends on the installation location and the size of the area to be monitored.

Can a leak sensor be installed on a water pipe?

A leak sensor can be used to detect water leaks in the vicinity of a water pipe. It monitors the area on or under the pipe, not the pipe pressure itself. When selecting a sensor, the potential leak locations, the pipe routing, and the desired response in the event of a leak are key factors.

What does IP65 mean for a leak sensor?

IP65 describes the enclosure's protection rating. Whether this protection rating is sufficient for the specific installation location depends on the local environmental conditions. The technical specifications of the selected product variant and the planned installation are always the determining factors.

Which model do I need for a longer monitoring range?

For longer distances, a model with a flexible sensor rod may be appropriate. Choose a sensor length that fully covers the relevant distance without unnecessarily complicating installation. For specific dimensions and connection requirements, please refer to the respective product page.
