Manufacturer: Geo-Integration

Product Description:

The Central Data Acquisition System (CDAS) is specifically designed to be used in engineering testing laboratories. The system consists of a personal computer for storing and controlling the HP Data Acquisition Unit (Model: 34970A) fitted with at least one (1) 20-channel (Model: 34901A) or 16-channel (Model: 34902A) plug-in multiplexer module. This unit is responsible for collecting signals of sensors or transducers through a series of transducer connection modules. A custom-made software is designed for enhancing the user interface and data management. The system is capable of recording up to 60 channels per data acquisition unit.

Computer Software:
The CDAS software is designed to collect real time data signals from the transducers or sensors via the data acquisition unit, which has the following main features:

Friendly user interface. It is run in Windows environment providing flexibility during data acquisition with menu bars and buttons.
Easy add task. It allows the user to add any task with simple windows, and it also allows easy modification on recording interval and number of readings during testing.
Multi-task capability. It enables one to record readings of different tasks at any time, producing a powerful tool in data acquisition and enhancing the capability of the acquisition unit.
Real-time on-screen viewing. The data can be viewed at any time in numerical and graphical forms during monitoring.
Data management. The data is stored in ASCII format, which can easily be linked to any commercial spreadsheet program, such as MS EXCEL? etc.
Automatic rebooting capability. If the computer crashes due to unforeseeable circumstances, rerunning the program from start will retrieve the incomplete tasks automatically, without having to re-entry the tasks for continuation of monitoring.
Transducer overloading warning system. It provides alarm system when the signals of the sensors have exceeded the limits set by the user, so that the user can take appropriate action immediately. This feature will reduce overloading or damage to the sensors through early warning.
Access security system. A multi-user log-in/log-out system provides simple solution to the supervisor in managing the system. The program has a simple security logging system for easy management.

Custom Made Transducer Connection Module:
The transducer connection module is used primarily to supply power to the transducers by means of a built-in regulated DC power supply. An AC or DC external power source is required to power the module. The power is regulated to produce a stable 2 volt DC or 5 volt DC or 10 volt DC supply depending on the sensor requirements. Each module is designed to connect up to four (4) sensors with one channel reserved for excitation voltage. The signals of the sensors can also be read manually by an external voltmeter through a push button system.

Types of Sensors and Transducers:
The data acquisition system can accept most strain gauge type transducers as well as thermocouples.
