DATA ACQUISITION SYSTEMS - DATA LOGGERS

Data acquisition, defines the transactions concerning the perception and sampling of physical condition and quantity in the real-world as electronic signals through the sensors, measurement of these signals by being transformed into numeric (digital) data and saving them in a computer.

(PHYSICAL QUANTITY – SENSORS – DATA ACQUISITION DEVICE – COMPUTER / SOFTWARE)
 
 
Technical Support Group is the manufacturer of data acquisition systems of Turkey since 2000.


At the present time, the systems used in the Civil Engineering departments of almost all the universities of Turkey, more over in the laboratories of Machinery, Grounding, Geological, Metallurgical/Materials and also worldwide have laid the foundations of the prestige and the credibility that TDG gained today.
 
The Data Acquisition System developed and produced by Technical Support Group under the brands e-QUAKE and TESTBOX can be divided into two main categories.

A) Quasi Static Data Acquisition Systems (up to 10 samples per second per channel)
B) Dynamic Data Acquisition Systems (up to 1K-16K samples per second per channel)
 
Large Sensor Compatibility
One of the most important features of the system being developed by the TDG is to be compatible with single (pek) sensor type by means of direct channel connectionwithout the need for extra power,feeding or signal processing module.

These devices, which can be directly connected to many commonly used sensors, especially according to their models and types, such as;
·         Strain Gauge
·         Accelerometer
·         Load Cell
·         Displacement / Position Sensor
·         LVDT
·         Potentiometrical Ruler
·         Micrometer
 
 
apart from that, they are compatible with the the sensors in many different categories such as the thermocouple, voltage/current entry sensors, pressure, humidity, etc. environmental sensors, inclinometer, tiltmeter settlement gauges, pore water pressure, earth pressure sensors.

 *: It is the standard minimum data acquisition speed, the higher-speed models can be produced.
**: 3 channels are reserved for standard internal accelerometer, and 1 channel is reserved for the connection of an external sensor.
***: The measurement resolution of the device differs as 10µm or 1µm according to the micrometer sensor to be selected.
****: Sensors of IEPE/ICP type, can be connected to certain models of these devices through IEP-CABLE, and can be connected directly to certain models.
****: The Strain Gaugeler, can be connected to certain models of these devices through Q-CABLE and can be connected directly to certain models.
O: Optional features are available.
