Submersible Tiltmeter (MEMS)
Submersible Tiltmeters measure tilt in two axial planes perpendicular to gravity vector, and are intended to be installed in locations either susceptible to submersion or fully submerged to provide long term observation with maximum resolution and sensitivity.
Overview
Overview
The system features a versatile, adjustable universal mounting bracket that can be installed vertically, horizontally, or at an angle, alongside an interconnecting cable and a data logger or readout instrument. The housing is IP68 rated up to 2 MPa for maximum resistance against water ingress. The cables are securely encapsulated within the housing, utilizing waterproof connectors capable of withstanding depths of up to 200 meters. Both bussed and non-bussed models are available, catering to daisy-chained or single-point setups. The Submersible Tiltmeter is compatible with handheld readouts featuring digital interfaces or can be seamlessly integrated into larger Data Acquisition systems.
Product Features
- Biaxial sensors
- Adjustable and easy-to-install mounting bracket
- Reduced cabling costs with daisy-chainable sensors
- Compatible with both data loggers and manual readouts
- Ideal for permanent submersible applications up to 200m depth (2MPa)
