SS4  Modules

Strain, Acceleration, Temperature

The SS4 is a high-resolution strain and temperature sensor with a 3-Axis accelerometer for dynamic or static structural monitoring applications. Each SS4 includes a single direction strain sensor in two package sizes for steel and concrete materials. Monitor stresses, temperature, rotation and motion with our very small form factor SS4 modules. Optional versions available for fully isolated signal returns and overvoltage protection up to +/- 40 volts.
