BPR-A-S
Small-sized Pore Pressure Transducer

Summary

Suitable for model experiments, Highly-sensitive, small levels of pore pressure.
Featuring an outer diameter of 20 mm, the BPR-A-S series is highly sensitive transducers for measurement of small levels of pore pressure. A watertight design enables embedment applications and makes them suitable for model experiments.

Features

●Small-size (20 mm diameter), small rated capacity (50 to 200 kPa) and high sensitivity (2000μm/m)
●Filter is stainless (standard 10μm)
