Pressure transducers
The KELLER PR-25Y is a high-precision piezoresistive pressure transducer, specifically suited for monitoring dynamic pressures exerted by wave impact on coastal rock faces. Its flush-mounted, fully welded stainless steel diaphragm (AISI 316L) makes it ideal for harsh marine environments, where it is exposed to saltwater, humidity, and significant thermal variations.

Rock temperature transducer
Rock temperature transducers measure the internal temperature of rock mass matrices. These sensors—typically thermistors or thermocouples—are installed in boreholes to monitor thermal variations at known depths.

TEROS-12 sensor
The TEROS-12 is an integrated sensor for use in soil or masonry, capable of measuring volumetric water content (0–0.7 m³/m³, accuracy ±3%), temperature (–40°C to +60°C, accuracy ±0.1°C), and electrical conductivity (0–20,000 µS/cm, accuracy up to ±5%). It offers high resolution and reliability for environmental and geotechnical applications.

Rod extensometers
Rod extensometers measure the opening and closing of fractures or discontinuities in rock and structures. They consist of a rigid rod anchored on one side of the fracture and a displacement sensor (often linear) on the other side. They provide critical data on the stability of slopes and civil engineering structures, indicating potential reversible or irreversible displacements.
