EARLY LEAK DETECTION ON THE CONSTRUCTION SITE
uring the construction phase, it is crucial to recognise leaks as early as possible. This effectively prevents environmental damage, repair costs and construction delays. Moisture penetrating walls, floors or ceilings can cause massive damage, especially from leaking water pipes.
Conventional methods such as manual pressure tests or selective visual inspections quickly reach their limits. What is missing is continuous, intelligent monitoring.
DIGITAL SOLUTION: THE LEAK MONITORING SYSTEM FROM AWOSSA With digital leak monitoring, AWOSSA offers a powerful and self-sufficient solution for the construction industry. The system recognises leaks at an early stage, alerts the user automatically and helps to prevent costly damage before it occurs.
Core functions of the system
Permanent recording and evaluation of pressure and temperature data
Real-time detection of leaks directly on the construction site
Automatic notification by e-mail or SMS when limit values are exceeded
Intuitive web interface for configuration and data analysis
HOW THE SYSTEM WORKS
The sensors continuously monitor the installation during the entire construction phase, and even the smallest deviations in pressure or temperature are reliably detected and the responsible persons are notified immediately.

PRECISE MEASUREMENT TECHNOLOGY: THE 23SD TRANSMITTER
AWOSSA relies on a specially developed solution from KELLER Pressure for pressure and temperature measurement: the 23SD series. The customised pressure transmitter is based on the proven 9LD pressure transmitter capsule, featuring chip-in-oil technology. The electronics are located directly
The integrated battery ensures self-sufficient operation. Once activated, the system automatically starts monitoring. All recorded data is transferred to the AWOSSA cloud in encrypted form using “Secure MQTT”. It is stored there and visualised graphically. Limit values can be conveniently and individually defined and customised via the web interface.
next to the pressure chip on the glass feedthrough. Thanks to its I2C interface, the 23SD can be seamlessly integrated into the AWOSSA electronics in a space-saving manner. The combination of fully welded thread and robust construction makes it ideal for tough everyday use on construction sites.
Advantages of the 23SD at a glance Minimised power consumption High measuring accuracy Excellent long-term stability No hysteresis
Fully welded construction
With digital leak monitoring from AWOSSA, potential leaks can be detected during the construction phase – quickly, reliably and completely automatically. A solution that not only creates safety, but also saves time and money.
