Titan Accelerometer
Salient Features
The Nanometrics Titan Accelerometer is a force-balance, triaxial accelerometer engineered for high-resolution structural and seismic monitoring. Designed to deliver robust performance across a broad frequency range (DC to 430 Hz), the Titan excels in capturing both strong ground motion and subtle ambient vibrations. With digitally selectable full-scale ranges and offset zeroing capabilities, the Titan is suited for deployments where precision, durability, and remote manageability are essential.
The Titan comes in three models:
-
TACCL-N1 (Surface Mount): Horizontal mounting, IP-67 rated aluminum enclosure
-
TACCL-V1 (Vertical Mount): Vertical mounting, IP-67 rated aluminum enclosure
-
TACCL-PH2 (Posthole): Downhole deployments up to 300 m, IP-68 rated stainless steel enclosure.
Key Specifications:
-
Dynamic Range: >150 dB from 0.01 Hz to 10 Hz
-
Full-Scale Ranges: ±0.25 g, ±0.5 g, ±1 g, ±2 g, ±4 g (selectable via Web UI or CLI)
-
Offset Accuracy: Zeroed within ±0.005 g
-
Communication Interfaces: RS-232 with Web and command-line interfaces
-
Power: 9–36 V DC input; 1.1 W typical power consumption.
Installation Tips
-
Pre-Configure Settings: Work with EPIC staff to set gain, range, and control line functionality prior to field deployment. Adjustments should ideally be made in batch before shipping.
-
Leveling and Orientation: Use built-in XYZ directional arrows, leveling bubble (on surface models), and locking screws for precise alignment. The Y-axis is typically aligned to true north or structural axes.
-
Secure Mounting (if >0.1 g expected): Use provided anchors for concrete, masonry, or steel surfaces. For <0.1 g sites, freestanding installation is acceptable.
-
Thermal Insulation: Enclose the unit in a rigid foam box for reduced noise in fluctuating temperature environments. Ensure the box does not contact the sensor or its cable.
-
Auto-Zeroing: Always perform auto-zeroing after installation to eliminate DC offset. This can be done through the Web interface or a digitizer's control pin.
-
Avoid Ground Loops: Where possible, ground only the digitizer and isolate the accelerometer's chassis.
