YieldPoint’s d-Tilt-EL is a dual-axis tiltmeter designed for semi-permanent installation in either a borehole or on surface, for geotechnical and civil applications. The technology is based on an electrolytic tilt sensor with a range of +/- 2o and an on-board digital temperature sensor. Each instrument is individually calibrated with coefficients stored in the micro-controller memory. Calibration sheets are available upon simple request.
The RS485 output signal is an ASCII encoded message that includes the unique Sensor_ID, the Sensor_Type as well as the temperature and tilt data. This eliminates the necessity for expensive analog-to-digital conversion so that the low-cost readout unit outputs data in real world units (arcdeg and oC). Readings can also be made using the USB port of a PC or a tablet computer (SensorViewer on d-Tab). A real-time Plug-and-Play network of d-Tilt-EL sensors or of any combinations of other YieldPoint Instrument can be built in minutes using a combination of the low cost d4Logger solution and the dMesh wireless mesh.
