True 3D Induced Polarization Equipment Multi-channel IP Acquisition Unit
Traditional induced polarization systems often force you to choose between portability and power, or between 2D profiling and true 3D imaging. The IP3D Series eliminates these trade-offs. This ultra-high voltage, high-power true three-dimensional time-frequency IP measurement system combines deep penetration, vector reception, and wireless node technology in one integrated package.
Power Without Bulk
A typical high-power IP transmitter might weigh over 100 kg and require a vehicle to move. The Hyper3K transmitter delivers 3000V and 80A (60kW) in a < 45 kg box (size <50x40x30 cm). You can carry it by hand or on a small cart.
- Series connection provides 6000V capability
- Parallel connection delivers up to 300A and 300kW
- Records full waveform current internally
- Streams data to receivers via 4G or LORA
- Supports time-domain, frequency-domain, and spread-spectrum IP (SSIP)
- SSIP reduces survey time by up to 70% compared to single-frequency systems
True 3D vs. 2.5D or Pseudo-3D
Many so-called "3D" IP systems actually use 2D lines interpolated. The IP3D Series enables true 3D measurement through array deployment with vector reception.
- IPU-4C receiver has 4 channels and 5 electrode terminals (N, E, W, S, G)
- Supports cross, L, or linear electrode patterns
- Records electrical field in multiple directions
- Provides complete 3D resistivity and IP models
- Supports 2D, 2.5D, and 4D (time-lapse) surveys
Noise and Dynamic Range - A Game Changer
Conventional receivers often have a dynamic range of 120-140 dB and noise floors above 20 nV/√Hz. The IPU-4C achieves > 180 dB dynamic range and < 6 nV/√Hz background noise thanks to 32-bit Sigma-Delta ADC and ultra-low noise circuit design.
- Resolves very weak IP signals that would be buried in noise on standard receivers
- Power frequency suppression >100 dB at 50 Hz
- Common mode rejection ratio ≥110 dB at 80Hz
- Channel crosstalk ≤-100 dB
Synchronization That Works Anywhere
Old systems use quartz clocks that drift hours per day, requiring frequent resynchronization. The IP3D Series uses a quad-mode GNSS chip (GPS, Beidou, GLONASS, Galileo) achieving ≤ 30 ns timing accuracy.
- Seismic-node-style synchronization locks quickly (2 minutes calibration)
- Maintains 1 µs accuracy for 24 hours
- Works under dense tree canopy or in deep valleys
- Critical for large 3D arrays requiring synchronous sampling
Wireless Everything - No Cables, No Connectors
Traditional receivers need physical USB cables for data download and separate chargers. The IP3D Series offers wireless charging and wireless data recovery via the WPU (single-port) and WPS-12 (12-port) stations.
- Each port provides 30W charging and 20 MB/s download
- WPS-12 handles 12 receivers simultaneously with total download 240 MB/s
- IP67 waterproofing allows operation in rain or shallow water
- Bluetooth, 4G, LORA, and NFC provide remote control and status monitoring
- View real-time results on mobile phone while standing next to receiver
