ST350 STRAIN TRANSDUCER

Description

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. Over 30 years of experience have proven these units to be the gold standard for accurate field measurements.
