Model ELC-32V is a vibrating wire type centre hole load cell used to determine the load in rock bolts, tieback anchors etc. It is suitable for measuring static or slowly varying stresses only. The tilt sensor works on the Micro-Electro-Mechanical Systems (MEMS) technology to provide a digital output. with high precision. Other sensors are also available on request. The civil engineering projects require an extensive amount of monitoring pre and post-construction to ensure everyone’s safety. Comparison of observed data with design assumptions, Determination and evaluation of design parameters, Testing of new construction materials and techniques. Geotechnical instrumentation and monitoring can assist design, construction and operation of a variety of geotechnical assets. Model ESDL-30MT Tilt Meter with Automatic Data Logger. The vibrating wire pressure transducer works on the vibrating wire technology to provide a digital output. It can also be epoxy bonded on concrete structures. Geotechnical instruments are the sensors that are used in the geotechnical field or large civil engineering projects to monitor the health of the structures. Geotechnical Engineering Standards ASTM's geotechnical engineering standards are instrumental in specifying, testing, and investigating the physical/mechanical properties and characteristic behaviors of surface and subsurface earth materials that are relevant to a construction project. Model EDS-20V-AW Vibrating Wire Arc Weldable Strain Gauge. Model EMA-11 Measuring Anchor/Rock Bolt Extensometer consists of a steel hollow anchor/rock bolt with a precise 4-point extensometer integrated into it. Groundwater Level Monitoring & Piezometric Pressure, Digital Inclinometer Installation in a Borehole, El Tiltmeters: Operation, Installation, & Applications, Lateral ground movement, Deformation, DisplacementStress, Strain, Load The range of geotechnical instruments and their application field is limitless. Geotechnical instrumentation, monitoring & testing; Conventional rotary core drilling with: Triple tube (NMLC) (HMLC), ZWF triple tube, TNW, T2-121 and T6-146; Split double tube (NWD4) and wireline drilling in the following sizes: PQ, HQ, NQ, BQ; Sonic Coring 6 “x 8” system; 4” x 6” system ; CPTu testing; In-situ testing Drilling and grouting Projects. The Model EAN-91M-B and EAN-93M-B beam sensors consist of model EAN-91M and EAN-93M tilt meter enclosures fixed on to a beam (1, 2 or 3m long) respectively. Visit our website to learn more. Model EAN-41M/EAN-42M (SDI-12) MEMS Beam Sensors. They are often used in conjunction with the EDS-80 tape extensometer and EDS-64 borehole extensometer to measure the performance of the lining and to determine whether the lining is thick enough to maintain stability. Roof or wall fall in an underground cavity is almost invariably preceded by measurable sag as the strata open up and the movement usually occurs at an increasing rate as of fall conditions. Model ECTD-30V and ECTD-60V CTD sensors are available for monitoring electrical conductivity, water level and temperature in the ground. Model EDS-20V-SW vibrating wire strain gage can be spot welded or epoxy bonded on steel structures and struts.
