Pressure Transducers
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.
Overview
Overview
Strain Gauge and Vibrating Wire Pressure Transducers come with either a 1/4” NPT thread or a 1/4” or 1/8” NPT port, for easy connection to pipes or other components of the hydraulic circuit to be monitored. Both transducers can be read dynamically if required by the application.
Highly reliable lightning protection is standard for the strain gauge transducer and for the vibrating wire transducer.
