Teknik Destek Grubu (TDG) products

TESTBOX 2010 series is a data acquisition system which is developed for applications in Structural Health Monitoring, Civil Engineering Earthquake Engineering and other dynamic applications. The product which has signal amplifiers at channel inputs is compatible with most of the frequently preferred sensors in Civil Engineering tests such as strain gauge, load cell in addition to FBA, MEMs, ICP and other type accelerometers. Thanks to simultaneous measurement character and high ADC resolution, this product which is mainly developed for ambient vibration and seismic applications is also an ideal solution for other civil, soil mechanics, geological and mining Engineering tests having static and dynamic characteristics. The device which accomplishes high technical performance at a very suitable cost compared to other similar products, has reached to widespread use in Turkey and other countries and has become the first preference of researchers in this area.

e-QUAKE Series has been designed with a state of art technological approach. This series contains Seismic Digitizers, Seismometers, Strong Ground Motion Recorders and Broadband Sensors at a dynamic range up to 140 dB and with a resolution of 24 Bits. Seismic Digitizers (e-QUAKE-DIGI) have 2 different versions including 3 and 6 channels. E-QUAKE DIGI is compatibale with all seismic sensor types including force balanced accelerometer (FBA), velocity sensors, broadband weak motion sensors. Whereas 3 component Force Balanced Accelerometer, Broadband and Short Period seismometers could directly connect to 3 channel version, the 6 channel version is an ideal solution for hybrid type measurements which contain both accelerometer and broadband band sensors (Accelerometer + seismometer).

These accelerometers are ultra low noise sensors which are based on force balance / electro-dynamic feedback technology, ±0,8g measurement capacity and named as SENSEBOX7021/22/23+ and 7031/32/33 depending on the number of axis included. This series is an ideal solution for Seismic Strong Ground Motion Monitoring, Ambient Vibration and Structural Health Monitoring applications, offering an impressive performance at a relatively lower cost.

SENSEBOX-BROAD-P Series seismometers provide a very smooth and low noise measurement quality ata very broad frequency spectrum with force balancing and force feedback characteristics. This model which is particularly developed for portable purposes, could also be preferred in permanent stations since it provides a measurement sensitivity beyond mobile use. This Sensor has a very robust structure and does not require any extra tool or procedure at transportation/ mounting stages.

e-QUAKE ACC Series has been designed with an innovative and state of art technologicalapproach.These accelerometers and strong motion recorders are developed at 2 different sensitivity levels, as ultra–low noise and low noise. Both versions include uni, bi and tri component options. e-QUAKE-ACC-21/22/23 provides a flawless measurement possibility with an ultra low noise level of only 130 nano-g/root-Hz. This version is based on force-balance and force-feedback technology. It is possible to measure accelerations at micro-g level with this device. In this form, e-QUAKE-ACC-2X series is an ideal solution for strong motion measurements, seismic networks, structural health monitoring under ambient vibration and microtremor measurements.
