Dynamic Strain Transducers (Electrical Resistance)

The Model ST-350 Dynamic Strain Transducer is used for structural testing and recording strains on steel structures, post-tensioned and pre-stressed concrete structures, etc., and for any structure in which a short-term live-load can be applied. The Model ST-350 is delivered pre-wired in a rugged housing that is easy and quick to install in any weather. These transducers are field-proven and have been used for more than 20 years to record strain measurements on all types of structures, often in harsh field conditions.
