ISSO-IPI borehole inclinometers
Downhole inclinometers–IPI are designed to measure the angle of deviation of the borehole section plane relative to the horizon. The main application is the monitoring of landslide processes and the control of horizontal and vertical ground movements. Principle of operation: the angle of inclination is measured using a micromechanical MEMS sensor oriented relative to the gravity vector.
Defines the maximum tilt angle that the sensor can register, usually expressed in degrees (for example, ±90°).
Reflects the minimum error when taking readings, usually indicated in degrees or fractions of a degree (for example, ±0,1°).
Ensures the operation of the sensor in conditions of high humidity and IP68 dust and moisture protection, which is important for operation in wells and difficult natural conditions.
