Vibrating Wire Uplift Pressure SystemModel No. TES-PU-20V
Product Description
TES-PU-20V is a vibrating wire uplift pressure measurement
system that uses a vibrating wire pressure sensor. It is designed
for monitoring uplift pressure of water in foundation of dams
and concrete structures. The sensor is similar to TES-PP-30V
except that instead of !lter, a 25 mm BSP adaptor is provided
for pipe connection. A perforated/non-perforated pipe is
inserted in the borehole, at the top of which TES-PU-20V is
attached through valves and !ttings.
Bourdon Gage Type Uplift Pressure SystemModel No. TES-PU-20G
Product Description
TES-PU-20G uplift pressure measurement system is similar to the above excepting that it incorporates a
bourdon gage with dial readout instead of vibrating wire pressure cell that requires an electronic
readout.
