Our cones <br /> also have variable capacity friction; sleeves <br /> i (Fs) and pore pressure (U). The pore <br /> Triaxial Geophones pressure can be measured at one of 2 , <br /> or Accelerometer locations, either on the face' the cone tip or <br /> (vp&vs) behind the cone tip; ; Pore pressure <br /> i dissipation data is recorded-¢automatically. <br /> All data is displayed in real time at the ground <br /> Inclinometer(1) surface, facilitating the t)n site decision <br /> l making process. Field data reduction, plotting <br /> Thermistor(T} ; I <br /> y' and CPT interpretation j�cart be carred out <br /> upon request. l <br /> Friction Sleeve(FS) 'I s <br /> Load Cells ie <br /> 5 <br /> f <br /> i Pore Pressure ;p <br /> Porous Filter Transducer(U) <br /> Element n <br /> p- Cone Tip(ac) l <br /> t <br /> EGG Geotechnical and Environmental in Situ Testing Contractors ` <br /> I h �� <br /> Los Angeles • San Francisca • Hou Istari • Aiken <br /> AVancouver • Edmonton • Salt Lake City •,r New Jersey <br /> Tel.(925)313-M Fax.(925)31 - = e aWl.gres g@eci&com <br /> .I l <br /> i <br />
