BPG-A-S
High-sensitivity Pore Pressure Transducer

BPG-A-S

Summary

Suitable for high sensitivity measurement of underground water level.
Featuring rated output of 4000μm/m, the BPG-A-S series pore pressure transducers provide a sensitivity twice as high as ordinary units. Thus, they are suitable for precise measurement of underground water level etc. by embedding in a well, etc.

Features

●High sensitivity (4000μm/m) and  high accuracy (±0.5% RO)
●Excellent temperature characteristics (±0.02% RO/℃)
●Cone filter attached (possible to replace to a flat filter)
