[Updated] Type of Data Loggers and How do they work? Civil Engineering is a complex and interesting field. To put it simply, data loggers are simply the devices that are interfaced with several other instruments or sensors to log data in real-time. Large construction sites or even civil engineering structures require continuous monitoring to maintain its health. As these sensors do their job, the Data loggers are responsible for collecting and recording data from the installed sensors for an assigned duration, at predefined intervals, without any physical/human intervention. Let’s take a look at the data loggers in detail along with their types, working principle, and more. What is a data logger? A data logger is usually a compact, battery-powered device and carries a digital processor.
Once programmed, commissioned and activated, the data logger can be left unattended to measure and record data from sensors. Man-made Concrete Structures Monitoring. All man-made concrete structures, such as civil infrastructures and residential buildings are constantly affected and degraded throughout their service life by various kinds of factors, such as ageing, fatigue, corrosion, and even natural disasters.
These factors collectively reduce the structures’ disaster resistance ability, and can sometimes lead to partial failure or even the complete collapse of the structures. The potential for such accidents is a direct threat to the safety of both lives and properties. With these rising concerns, structural health monitoring of concrete structures has become one of the top research focus areas in recent years.

Rohtang Pass Tunnel Case Study - Geotechnical Monitoring & Instrumentation - Encardio Rite. Types Of Strain Gauges: Construction & Specifications. The EDS-30V shotcrete strain gauge can be considered as a miniature high resolution vibrating wire displacement sensor in a stainless steel housing.
It is pre-tensioned at around the middle of its measurement range using a very thin aluminium tubing so that it can measure both tensile and compressive strains of up to 30,000 microstrains unit. Two short lengths of rebar are fixed, parallel to each other, at each end of the strain gage for gripping in shotcrete. The distance between the rebars is the gauge length of the strain gauge. The aluminium tubing is covered with a polyolefin sleeve to decouple it from the surrounding concrete so that the measured strain is the average strain in concrete lying between the two lengths of rebar.
The sensor houses a permanent magnet and a plucking coil assembly. Al Mirani Fort Monitoring Instrumentation by Encardio-rite. Fort Al Mirani is a fort in the harbour of the city of Old Muscat, Oman.
On showing signs of decay and distress, it was restored to its original majesty as part of a concerted renovation program. The surrounding saline weather conditions and numerous rainwater discharge points had caused adverse weathering and erosion with time. The Sultanate commissioned Atkins International and later Constell Consultants India to prepare a report on protection of the fort and to suggest long term performance monitoring. Harry W. Nice Memorial Bridge – A Case Study. Bridges constitute a very important component of the transportation network.
As they are a major investment for society and are at the core of public transport and usage, it is extremely crucial to keep an eye on their safety and maintenance. This is achieved through geotechnical instrumentation and monitoring, which is involved in the pre, post, and after-construction phases. Safety in bridges is a bigger concern that other parts of the transport system since any damage or collapsing of the structure can lead to magnanimous devastation to life and property with severe consequences. With this understanding in mind, Encardio-rite makes use of modern technologies, instruments, sensors, and real-time assessment of the bridge to observe and keep a track of all the activities that might affect the foundation of the structure. In this article, we are taking a look at one such project that was carried out by Rite Geo System, Encardio-rite’s USA Subsidiary. Strategic Tunnel Enhancement Programme (STEP) STEP (Strategic Tunnel Enhancement Programme) constitutes one of the largest tunnel sewerage systems in the world.
This huge gravity-driven hydraulic wastewater network tunnel was divided into 3 sections: Main Sewer, Link Sewer, and the Pumping Station. In-place 3D inclinometer /settlement (IPIS) system. The length of the spacer tubing is what decides the distance between each sensor; the length of each segment where the tilt is monitored. Our Inclinometer sensor possesses a displacement range of 100mm which helps to measure the expected settlement/heave. It is labelled at three locations which are the two ends and the middle for ease in setting. A coarse adjustment of 5 mm / 50 mm / 75 mm and a fine adjustment of 50 mm (± 25 mm) is provided in the gage tube for the positioning of the settlement sensor over the ring magnets. Even the gage tube is put together in parts. There are several advantages of the digital probes over the conventional analog probes. For this reason, when we have to employ several sensors, SDI-12 equipped 3D probes are the perfect choice as they aren’t restrictive when it comes to accomodating a larger number of individual signal cables inside the borehole.
Bridge Structure Health Monitoring Projects By Encardio-rite. Model EAN-61MS in-place 3D Inclinometer System (IPIS) Encardio-rite model EAN-61MS in-place 3D inclinometer cum settlement (IPIS) system is used wherever lateral movement along with settlement/heave is to be monitored in a borewell or on a structure. It finds wide application in the measurement of lateral movement and settlement in soil, earthworks, slopes or structures like retaining/diaphragm walls, embankment, deep foundations or dams etc. It is also very useful in monitoring landslide areas. IPIS is designed to provide significant quantitative data on the magnitude of lateral movement along with settlement or heave and its variations with time. It also provides the pattern of deformation, zones of potential danger and effectiveness of construction control measures undertaken.
What Are The Different Types Of Piezometers? The Model EPP-30V, vibrating wire piezometer consists of a vibrating wire and coil magnet assembly enclosed in a stainless steel body electron beam welded to the diaphragm. The welding creates a vacuum of around 1/1000 Torr inside the sensor to protect it against water and other corrosive materials present in it. The use of the piezometer is to gauge the pore water pressure in the soil, earth, rock-fill foundations, and concrete structures. The stainless steel body of the piezometer makes sure that it is unaffected by common chemical corrosion.
There’s a ceramic flat filter with low air entry value along with a grain size of 40-60 microns. The water that seeps through the internal pores or seams in mass concrete structures, rock formations of dam foundations, foundation soil of structures, reclaimed land soil etc. penetrates through the ceramic filter thereby, exerting pressure on the diaphragm. ESCL-10VT-BX Datalogger Sensor on Encardio. Vertical In-place Inclinometer – Operating Principle & Installation. Each of the in-place sensors is equipped with pivoted sprung wheels, that are designed to fit perfectly inside the grooves of the inclinometer casing.
Length of spacer tubing is used to estimate the distance between each sensor; the length of each segment over which the tilt is monitored. Spacer tubing length (mm) = gauge length (mm) – 381 mm The outside diameter of spacer tubing = 19 mm. Dubai Metro Case Study: Monitoring the Longest Driverless System. Dubai metro is the first urban network to run in the Gulf Arab States and is the longest automated driverless system in the world. With the metro running underground in the city centre, from the Sheikh Rashid/Sheikh Khalifa Bin Zayed intersection to Salahuddin/Abu Bakr Al Siddique intersection on the Red line and from Garhoud to Oud Metha Road on the Green line, it has provided a safe and swift commute to thousands of workers in the country. The Green and Red line were the first to be monitored and constructed, which was done in two different phases.
Phase 1 included the Red Line running from Al-Rashidiya to Jebel Ali, a 53km long rail line connecting 26 stations. Out of this, 5.6 km of the line and four stations operated underground. This took place for 2006-2009. Complex Structures Monitoring and Instrumentation. Geotechnical Monitoring and Instrumentation at Encardio Rite. Seismograph & Accelerometer.
