Strain Gauge and Vibrating Wire Pressure Transducers

Brochure

DESCRIPTION

Strain Gauge and Vibrating Wire Pressure Transducers are used for uplift measurement in the foundation of concrete dams, overflow settlement measurement in earthfill and rockfill dams, and all other applications where a rugged and reliable pressure transducer is required for measuring fluid pressure in closed circuits. The pressure transducer comes with a 1/4” NPT thread, or NPT port, for easy connection to pipes or other components of the hydraulic circuit to be monitored. The strain gauge transducers can be read dynamically if required by the application.

APPLICATIONS

  • Uplift pressure measurement in concrete dam foundations.
  • Retrofit of earthfill dam settlement systems.
  • Fluid pressure measurement in closed circuits.
