ST350 Strain Transducer
The ST350 Strain Transducer has been designed to quickly and accurately measure strain on a variety of structures in harsh field environments. This 350Ω full Wheatstone bridge strain transducer is very accurate, rugged, and waterproof. Providing roughly 3.5 times the output of a typical foil strain gage, these reusable sensors are ideal for measuring live-load strain on structures and can be installed within minutes in all weather conditions.
