In-Place Inclinometer Sensors

Merek : Slope Indicator (Sinco)- USA

Deskripsi Dan Spesifikasi:

Aplikasi 
Sensor In-place inclinometer ideal untuk penggunaan jangka panjang dan pemantauan yang rapat secara terus menerus dengan biaya operasional yang lebih murah dalam pengambilan data. tipikal penggunaan antara lain :
• Pemantauan deformasi pada dinding penahan tanah atau dindin penahan aktivitas ekskavasi
• Pemantauan pada pergerakan lapisan bawah tanah atau struktur dibawah tanah seperti Tunnel.
• Pemantauan deformasi pada aktifitas timbunan maupun dinding penahan.
• Pemantauan terhadap kelongsoran, lereng, pergerakan bendungan, jalan raya, yang sekaligus sebagai bisa digunakan sebagai peringatan dini.

Gambaran Pengoperasian
Sistem ini terdiri atas beberapa jumlah sensor pada satu titik pembatauan yang dipasang didalam casing Inclinometer.
Casing Inclinometer tersebut merupakan akses bagi rangkaian sensor yang akan dimasukan kedalam kedalaman tertentu untuk melakukan pengukuran nantinya. jalur yang tersedia pada casing berfungsi untuk menjaga sensor tetap pada orientasinya.

Casing Inclinometer dipasang pada daerah yang dianggap akan terjadi perubahan, ditanamkan vertikal sampai kepada lapisan keras/ atau pada lapisan tersebut diasusmsi tidak bergerak. Pada casing inclinometer terdapat jalur roda dua arah yang disesuaikan dengan estimasi pergerakannya. Setelah itu Rangkaian sensor dimasukan kedalam casing yang sudah terpasang pada zona yang diasumsi akan terjadi pergerakan,
Saat terjadi pergerakan maka casing yang telah terpasang tersebut akan ikut melengkung yang kemudian akan dibaca oleh rangkaian sensor didalamnya.
Pengukuran inklinasi dari sensor nantinya akan menghasilkan suatu gambaran grafis yang menunjukan ada atau tidaknya perubahan. apabila terjadi perubahan maka pada telah terjadi deformasi pada kedalaamn tersebut.

In most applications, sensors are connected to a data acquisition system, and readings are transmitted to processing software that can trigger alarms based on displacements or rate of change.

Advantages
Real Time Monitoring: The in-place inclinometer is ideal for continuous, unattended monitoring and can deliver readings in near-real time.
Single-Cable Installation: Each sensor connects to the sensor above, effectively reducing the number of signal cables to one. This eases installation and simplifies connection to the data logger.
Flexible Configurations: Because sensors are connectorized rather than hard-wired, it is easy to extend or shorten sensor chains. In addition, sensor gauge lengths are easily changed to optimize coverage of important zones, yet minimize the total number of sensors in the chain.
Durable Components: Sensors, cables, connectors, and wheels are exceptionally durable, making it practical to remove the sensors at the end of the project and redeploy them on other projects.
Complete Solutions: DGSI offers complete monitoring solutions that include data loggers and Atlas webbased monitoring software. Atlas can check for alarm conditions in nearreal time and can present plotted data immediately after the readings are obtained.

Konfigurasi Sistem :

SERIAL SYSTEM CONFIGURATION
A serial IPI system requires inclinometer casing,
serial sensors with wheels and gauge tubes, a
suspension kit, and a jumper cable.
Inclinometer Casing: Choose 70 mm or 85 mm (2.75 or 3.34 in) diameter inclinometer casing.
Uniaxial or Biaxial Sensors: Uniaxial sensors measure tilt in the plane of the wheels. Biaxial sensors include a second sensor that measures tilt in the plane perpendicular to that of the wheels.
Wheels: Choose wheels to fit 70 mm or 85 mm casing. Order sensor wheels for each sensor, and
one top wheel for each chain of sensors.
Tubing for Gauge Lengths: Order gauge tubing for each sensor. Tubing is sized to make exact gauge lengths of 1, 2, or 3 m. Custom
gauge lengths can be special-ordered.
Signal Cable: Serial sensors include signal cable sufficient for gauge lengths up to 3m. Cables have connectors that allow them to be joined
into a bus. A bottom plug is required for the bottom of the bus. A jumper cable connects the top of the bus to the data logger.
Top Suspension Kit: Order one top suspension kit for each installation. The kit includes hand ring, chain, hook, cable thimbles, and clamps. Requires stainless steel cable, not included.
In-Line Suspension Kit: The in-line suspension kit is used to suspend an independent chain of sensors from the chain above. This allows monitoring of two or more widely separated zones. The kit includes cable thimbles and clamps. Requires stainless steel cable, not included.
Data Logger: The Slope Indicator M-Logger is specifically designed to read MEMS sensors. It can operate a single chain of up to 16 sensors.
The M-Logger can also be used to verify operation of the sensors at installation time. The Campbell Scientific CR1000 data logger can operate 6 chains of serial sensors and the CR800 logger can operate 3 chains of serial sensors.
Data Reduction Software: Readings retrieved from the logger can be processed manually by spreadsheet or automatically by the Atlas webbased monitoring system.
