What TDG does

TDG (Teknik Destek Grubu), legally TDG Deprem ve Yapı Sağlığı İzleme Sistemleri Ltd., is a privately held Turkish engineering technology company founded in 2000 and headquartered at METU Teknokent in Ankara. The company is the only manufacturer worldwide offering a fully integrated vertical stack for structural health monitoring (SHM), earthquake early warning, and servo-hydraulic testing — encompassing ultra-low-noise force-balance and MEMS accelerometers (SENSEBOX 7000/7020 series), 24-bit dynamic data acquisition systems (TESTBOX1001 quasi-static and TESTBOX2010-FIELD/RACK portable and rack-mounted digitizers), three-component strong motion recorders (eQUAKE-NOVA), P/S wave detection systems (eQUAKE-SMART), servo-hydraulic and electro-mechanical shake tables (250 kg to 50-ton capacity), servo-hydraulic actuators (up to 200 tons), seismic isolator test machines, and a proprietary software ecosystem (TDG-MONSTER, TDG-SHMWEB, EASYTEST family, EQLAB). TDG also operates what it describes as the world's first real-time 7/24 Structural Health Monitoring Center, processing continuous data from instrumented buildings. Products are developed at TDG Laboratories and manufactured in Turkey with Yerli Malı Belgesi local-content certification.

The company generates revenue through one-time capital equipment sales (hardware dominant) plus bundled systems integration, installation, commissioning, calibration, and consulting services — with no publicly disclosed recurring subscription pricing model. Distribution is exclusively direct, via phone, WhatsApp, email, and project-based quotation targeting enterprise and institutional buyers: civil engineering and earthquake research laboratories, university research departments, government agencies (AFAD, T.C. Merkez Bankası, Ziraat Bankası), high-rise commercial real estate developers, hospitals with seismic isolation systems, airports, dams, energy/industrial facilities, heritage sites, and increasingly residential buildings. Go-to-market is anchored by technical publication of peer-reviewed papers at structural health monitoring conferences (SMAR, 7ICEES, idRC, 3TDMSK) and participation in Turkish government research programs (TÜBİTAK ARDEB-1001). The company claims installations in 40+ countries across academic institutions (Caltech, Centrale Nantes, Imperial College London, University of Queensland, University of Bologna) and large-scale commercial projects including the Groningen Netherlands regional SHM project (~400 axes for Fugro), 100+ monitored buildings in the Philippines, 20+ Turkish hospitals with seismic isolators, and heritage sites including Divriği Ulu Camii UNESCO World Heritage (200 sensors).

Broad incumbents

• National Instruments (NI): Large incumbent in modular data acquisition systems (PXI, CompactDAQ) used widely in laboratory and field test environments. Overlaps with TDG's TESTBOX2010 digitizers in laboratory DAQ and is often the alternative against which TDG competes in academic research lab tenders.
• Brüel & Kjær (HBK): Global leader in sound, vibration, and structural test instrumentation (sensors, DAQ, modal analysis software). Overlaps with TDG's SENSEBOX accelerometers, TESTBOX DAQ, and structural dynamics software offerings but serves a much broader industrial and NVH customer base.
