ST350 Strain Transducer
The ST350 uses Wheatstone bridge circuitry, which converts small changes in resistance to an output voltage that our data loggers can measure. Its construction avoids the tedious and time-consuming effort required when using foil strain gages. This allows the ST350 to be installed within minutes on steel, concrete, timber, and FRP members.
Benefits and Features
- Improved signal-to-noise ratio means higher-resolution measurements
- Rugged enough for harsh environments
- Pay for themselves with just a few uses
- Compatible with most Campbell Scientific data loggers
- Quick installation with minimal preparation
- Efficient, reliable, and highly accurate
The ST350, manufactured by Bridge Diagnostics, Inc., is a strain transducer used to evaluate live-load stresses on structures such as bridges, buildings, cranes, and amusement park rides. It is prewired to connect directly with our data loggers, and is ideal for structural monitoring data acquisition systems.
- Evaluates live-load stresses on bridges, buildings, cranes, and other civil structures.
- With minimal surface preparation, you can quickly install the transducer and avoid the tedious and time-consuming effort involved when using foil strain gages.
- Rugged and can be installed in any weather.
- ST350 Strain Transducer can be installed within minutes on steel, concrete, timber, and FRP members.
- Compatible with most Campbell Scientific dataloggers.
