Introduction
The UltraEM Z5 Magnetotelluric System represents a groundbreaking advancement in geophysical exploration technology. Designed to address the complexities of modern subsurface investigations, this system integrates broadband electromagnetic sounding (10kHz–10000s) with multi-method compatibility (HMT, AMT, BMT, MT, CSAMT, TEM, IP). Its robust architecture combines GNSS synchronization (30ns accuracy) and real-time data processing, making it indispensable for industries ranging from oil and gas exploration to deep geothermal resource assessment.
Core Features
Ultra-Wideband Frequency Range
The system supports four distinct operational modes:
High-Frequency Magnetotellurics (HMT) for shallow-depth surveys (100kHz–10Hz, up to 1,000 meters).
Audio Magnetotellurics (AMT) for mid-depth analysis (10kHz–0.1Hz).
Long-Period Magnetotellurics (BMT/MT) for deep geological studies (1kHz–10000s).
This flexibility ensures adaptability to urban engineering projects, mineral prospecting, and large-scale tectonic studies.
Unmatched Synchronization Stability
Leveraging dual synchronization modes—GNSS satellite timing and thermostatic crystal oscillators—the Z5 maintains <30ns synchronization accuracy even in GNSS-denied environments. This guarantees uninterrupted data integrity during prolonged field operations.
Real-Time Data Acquisition and Imaging
Equipped with an embedded real-time operating system and parallel hardware processors, the system delivers instantaneous calculations of electromagnetic field power spectra, apparent resistivity, and phase profiles. Field technicians can visualize scalar or tensor datasets on-site, drastically reducing post-processing delays.
Multi-Source Compatibility
The Z5 seamlessly integrates with artificial sources (CSAMT, IP, TEM) and natural field sources, enabling hybrid survey configurations. It also supports conventional seismic recording (refraction, reflection) and micromotion monitoring, making it a universal geophysical toolkit.
Lightweight and Rugged Design
Weighing just 3.5kg with an IP67 waterproof rating, the Z5 is engineered for harsh terrains. Its modular expandability allows integration with third-party sensors (e.g., AMTC-30, MTC-150) and transmitters (e.g., T30, GDD-30).
