Installation

The A906 borehole inclinometer is designed to be integrated into a housing, molded or embedded (pressure resistance: 5 bar).
It can be installed horizontally or vertically.

Installation

Multiple 906 inclinometers can be connected together to create a high-precision instrumentation system for boreholes extending several tens of meters deep. All required accessories are available on request.

Configuration

The supply voltage range is 8 to 24 VDC.
Delivered as standard with a 3 m cable, customizable on request.
A remote monitoring solution is also available to complement the instrumentation and allow remote access to the measurements.
