The MEMS Portable Inclinometer System utilises the very latest in Bluetooth and MEMS (Micro-Electro-Mechanical) technology to provide fast and highly accurate readings.
The system comprises a slimline probe (detachable), lightweight cable reel and a rugged PDA (Personal Digital Assistant) which is used to view and/or download data at the borehole.
The probe is fitted with guide wheels and contains MEMS accelerometers measuring tilt in two perpendicular planes: One in the plane of the inclinometer wheels is known as the A axis; the other, in a plane perpendicular to that of the wheels, is known as the B axis.
Kevlar® reinforced cable is mounted on a lightweight, tough plastic reel which houses the Bluetooth module for wireless communication to the PDA. The cable is attached to the probe via a waterproof (to 1500m) quick connection which allows the probe to be detached, significantly reducing transport costs when returned for re-calibration.
The probe contains ‘on board’ calibration making it completely interchangeable with any reel. A MEMS Spiral Sensor is also available and is also compatible with any reel.
