GTI-E210-S
Pad-type Soil Pressure Transducers

Summary

The surface of transducer-installed segment is smooth and does not disturb soil pressure distribution.
Soil pressure transducers in GTI-E210-S series provide a pressure-sensing pad for installation along the curvature of a segment in shield driving applications. Thus, these transducers can accurately measure average soil pressure applied to a wide area of a segment or back-filling.

Features

● Large-sized pressure-sensing surface enables detection of average soil pressure.
● Sensor can be installed without any loss of the segment section due to blocking.
● Smooth segment surface after installation does not affect soil pressure distribution.
● Can be installed independent of the type of segment or engineering process.
● Can be installed even to a surface having a curvature. (For the limit of the curvature, contact a KYOWA representative.)

To Ensure Safe Usage

●The pad is made of a thin metal sheet. Do not strike it against any sharp or angular matters.
●Mounting fixture is required for installation.
