The stress / strain sensors can be installed vertically or horizontally.
Stress / strain sensors without sensor electronics can be fitted fix cable with a maximum of 20 m. These cables are connected to the multiplexer with sensor electronics. If the sensors are further away than 20 m cable, for example in a long pile or to measure at the sole earth pressure, sensor electronics for embedding in concrete is necessary. This sensor electronics is connected to a long distanze cable to the datalogger.
