The CorroWatch Multisensor is integrated into the concrete cover of newly constructed concrete structures. This device is designed to measure various critical parameters to evaluate the corrosion status.

It features four measuring electrodes made of black steel (anodes) positioned at different locations, maintaining a known distance from the reinforcement, along with a measuring electrode made of noble metal (cathode). The height of the anodes is adjustable to accommodate the thickness of the concrete cover.

To forecast the onset of corrosion in the reinforcement, the current flowing between the individual anodes and the cathode is monitored using either a specially designed handheld zero-ohm ammeter or a custom-built data logger. A notable increase in current indicates the initiation of corrosion.

The CorroRisk probe has been designed specifically for existing concrete structures, utilizing the same measurement principles as the CorroWatch probe, which is intended for new constructions. This probe allows for the early prediction of reinforcement corrosion, well in advance of its onset.

The CorroRisk probe is typically positioned within the concrete cover, situated between the surface and the outermost layer of reinforcement. The measuring electrodes, or anodes, are specifically engineered to be installed at various predetermined depths within the cover layer. Measurements can be conducted using a specially developed ohm-ampere meter or through a uniquely designed data logger.

The Standard Deformation Sensor is for surface mounting or embedding in concrete and mortars. This is ideal for long-term structural deformation monitoring which has 20-year track record in the field applications.

SOFO deformation sensors function as transducers that convert variations in distance into changes in the path imbalance between two optical fibres, which can be accurately measured using a SOFO VII Reading Unit.

The sensor is composed of two main parts: active and passive. The active part contains the reference and the measurement fibres and measures the deformations between its two ends. The passive part is insensitive to deformations and is used to connect the sensor to the Reading Unit. The output is terminated with an E-2000 connector with a built-in protective cover. The sensors can be quickly and easily surface mounted or directly embedded in concrete and mortars.

The MuST FBG deformation sensors function as transducers, converting variations in static or dynamic distances into alterations in the reflected wavelength of a pre-stressed Fiber Bragg Grating, which can be accurately measured using smart reading units.

The sensor consists of two components: an active part and a passive part. The active component houses the measurement fibre, which detects deformations between its endpoints and converts these changes into a wavelength shift of the Fiber Bragg Grating. Conversely, the passive component is unaffected by deformations and serves to link the sensor to the Reading Unit. Additionally, a loose Fiber Bragg Grating can be integrated into the passive section for temperature measurement and compensation purposes.

The sensors are available in single-ended, double-ended, or chained arrangements. With our Readout Units, it is feasible to connect as many as 7 full-range temperature-compensated sensors on a single channel, or alternatively, 4 temperature-compensated sensors alongside 4 non-compensated ones. The sensors are equipped with E2000-APC connectors or can be customized according to user specifications.

The installation of the sensors is straightforward and efficient, ensuring that the construction timeline remains unaffected. They can be seamlessly integrated into concrete and mortars or mounted on the surface.
