The In Place Inclinometer (IPI) is designed for near vertical borehole applications, the principal operation and data obtained are similar to the traversing type inclinometer systems such as the portable Digital Bluetooth Inclinometer systems. The In-Place Inclinometer (IPI) is used to measure lateral displacement within a borehole. Most commonly, the IPI is used in a system where multiple IPIs are installed at varying depths. In this manner the profile of the displacement can be monitored. The IPI itself consists of one or two (uniaxial or biaxial) MEMS tilt sensors mounted in a stainless steel housing. Each sensor incorporates an on-board microprocessor which performs an automatic temperature compensation of the tilt (g) data.
