Extreme Precision Geophysical Tiltmeter Selector Guide

Product catalog summary

Specifications Overview:
The document provides detailed specifications for various series of tiltmeters, including angular range, resolution, repeatability, scale factor, non-linearity, time constant, and temperature coefficients. Key specifications include:

Angular Range: ±0.5° to ±70°
Resolution: 1 to 10 µrads
Repeatability: 0.1 to 1 µrads
Scale Factor: µrad/mV or °/V
Non-Linearity: 0.4% to 2%
Temperature Coefficients: Ks and Kz values provided

Procedures and Features:
The tiltmeters feature built-in micrometer leveling legs, switchable gains, and low-pass filter settings. They are designed for high precision with resolutions as low as <25 nrad and virtually zero long-term drift. Output is a stable ±8 DC voltage (±16 VDC differential).

Operating Conditions:
The tiltmeters operate within a temperature range of -40°C to +85°C and are available with different power requirements and sealing options, including IP65 and IP50 ratings. They are suitable for harsh environments with submersible options rated up to 5,000 psi.

Applications:
These instruments are used in volcano monitoring and precision metrology, highlighting their capability in high-precision and demanding environments.

Customization Options:
The 700 Series offers customizable features such as measuring range, bandwidth, input power, output signal, damping, product dimensions, and more, allowing for tailored solutions to specific needs.

Additional Information:
For complete specifications and ordering information, users are directed to visit the manufacturer's website. The document notes that specifications are subject to change due to ongoing product development.
