STANDARDS : BS 1377:5; ASTM D2435, D3877, D4546; AASHTO T216 CEN ISO/TS 17892-5

The PRS-ZE0300 Front Loading Oedometer is rigidly constructed to ensure minimum frame distortion. The frame is designed to load the specimen through a lever arm assembly and one of three alternative beam ratios as 9:1, 10:1 and 11:1. The beam is fitted with a counter balance weight and beam support jack. The cell platform will accept the complete range PARSROS consolidation cells and is fitted with a central spigot to ensure accurate centering of the cell under the loading.
 
The PARSROS fixed ring consolidation cells are manufactured from corrosion-resistant materials and conform to the requirements of the relevant standards. An integral water reservoir is incorporated in the cell which allows the specimen to be inundated when required. All cells are supplied complete with upper and lower porous disc, pressure pad and cutting (specimen) ring.
The One-dimensional Consolidation test is used to determine    the consolidation characteristics of soils of low permeability.
 
Tests are carried out on specimens prepared from undisturbed samples. Data obtained from these tests together with classification data and a knowledge of the soils loading history, enables estimates to be made of the behavior of foundations under load. Consolidation cell, dial gauge or displacement  transducer and data logger, bench, weights, apparatuses for prepare Consolidation samples and calibration disc should be ordered separately.

Data Acquisition & PC Software

4 or 8 channel static uniloggers (PRSG-0320 or PRSG-0325 ) are used for recording  displacement data over time.

• High resolution : 260.000 points.
• Serial port for PC and printer connection.
• CPU card by microprocessor 32 bit ARM risk architecture.
• 4 or 8 analogical channels for displacement transducers.

The PARSROS consolidation software is developed according to ASTM D2435, D3877, D4546, BS 1377:5 and AASHTO T216 standarts to use with static unilogger systems. The displacement transducers are connected to unilogger and unilooger is connected to PC by RS232 serial output. The software is capable monitoring the chance of displacement data over times. The user can start recording of vertical displacement and stop current recording proses. The user can enter time intervals(or select fixed time intervals) and stress for calculattion consolidation test data.
 
The consolidation software have 8 different columns which can be set to different normal load values. The user can also manually enter the vertical displacement to these columns. The time-displacement pairs are drawn to square root time and logaritmic time graphs. The software can calculate enginnering terms like as square root t90, t50, t100, mv, Cv.
 
These calculations are done respect to the standarts requirements by using best line algorithms.Since these parameters require an engineering perspective while making comments, all test data and graphs are exported to Microsoft Excel for further investigations.

• Foreign Language Support and Customizable User Interface
• Graphical outputs and reports can be saved as  a MS Excel worksheet
• Maximum Flexibility to edit report and graph templatesTypical Loadin
