Pitch and Roll Micro - Electro - Mechanical Sensor (MEMS) - MicroTilt

View 3D More Pictures Brochures Manuals

The CDL MicroTilt is a tiny, dynamic, pitch and roll sensor for use in a huge variety of applications. Measuring only 55mm x 37mm x 26mm OEM (matchbox size) the unit can provide highly dynamic pitch and roll readings at a frequency up to 50Hz.

The tiny size is possible by utilising MEMS (Micro-Electro-Mechanical Systems) sensors. MEMS is the integration of mechanical elements, sensors, actuators, and electronics on a common silicon substrate through the utilization of microfabrication technology.

At an output rate of 50Hz the sensor returns an accuracy better than 0.5 degrees over the range of +/- 30 degrees. A range of oversampling settings allows the selection of output rates down to 1Hz, where the accuracy is better than 0.2 degrees.

A topside software package provides graphic and numeric indication of the pitch and roll readings and allows the selection of a variety of data output formats.

Internal DIP switches allow the selection of various options within the device.

A surface version and two subsea versions (3,000m and 6,000m) are available. The unit can also be supplied as an OEM part for inclusion in your equipment.
