The standard installation depth for moisture or corrosion sensors is limited to 12 in / 30 cm. However, it is possible to achieve a depth of over 328 ft / 100 meters in concrete by using an extended antenna. With the extended antenna setup, the reading unit and the measuring unit are housed in two separate enclosures and connected with a permanent cable link. This allows, for example, measuring at water level in a shipyard while conducting readings from the top of the quay wall. Besides increasing the installation depth, the extended antenna setup can also be utilized to establish reading points, enabling efficient online monitoring with a gateway.
