Pressure Cells
Transducer with a front diaphragm for measuring earth and fluid pressures, especially in tunnel boring machines or in test rigs with bulkhead connections.
Type B
Tangential Pressure Cell
Pressure cell to measure stress in concrete, mostly used to determine tangential pressure in shotcrete usually in tunnel linings.
Type F
Radial Pressure Cell
Pressure cell to measure stress in the contact zone concrete/rock, mostly used to determine radial pressure in NATM style tunneling.
Type S
Shuttering Pressure Transducers
Sensor for the determination of the pressure on formworks e.g. retaining walls.
Type E
Earth Pressure Cell
Pressure cell to measure total pressure in earthfill dams, embankments or earth pressure below foundations.
Type RE
Reference Pressure Cell
Pressure cell to determine total pressure and the possible change in inclination due to deformations in the underground.
Type BB
Stress Monitoring Station
System of several differently oriented pressure cells to determine the stress tensor and possible stress redistribution.
Type EPE
Push-In Pressure Cell
System for total pressure measurement in soils and earth fills that allows a push-in installation. Also available in a EPE / P version with integrated pore water pressure sensor.
Type EESK
Front-Membrane Pressure Cell
Sensor with front-membrane to measure earth or fluid pressure, especially in TBMs or in test facilities with bulkhead connections.
Type EM
Model Pressure Cell
Instrument for total pressure measurement in the laboratory or on a model scale.
Type FJ
Flat Jack
Pressure pad to determine insitu stress conditions in rock or structures made of concrete or masonry.
