The highly accurate ST350 Strain Transducer from Bridge Diagnostics brings great efficiency and reliability to measuring live-load stresses on 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. The ST350 is rugged and can be installed in any weather.
Features
- Used for recording
strains on highway bridges, railroad bridges, lock gates, amusement
park rides, and other structures in which a short-term live-load can be
easily applied.
- Attaches to steel, prestressed and reinforced concrete, and timber
members in 5 minutes.
- Provides between three and four times the output of a typical
quarter-arm foil gage installation. Improved signal-to-noise ratio
means higher-resolution measurements.
- Can be used with most data acquisition
systems that support full-bridge type sensors.
- Pay for themselves
with just a few uses.
- Used over the last two decades for recording millions
of strain measurements on all types of structures, often in harsh field
conditions.
