The d-micro strain gauge is capable of 1 micron resolution over a range of 10mm. The gauge is attached to the structure using the #8-32 threaded rod at either end. The length of the sensor is 250mm and the diameter of the body is 7mm.
An on-board microcontroller provides temperature compensation, applies a 10-point calibration algorithm, and outputs an ASCII encoded RS485 (9600, 8, N, 1) signal.
The output signal includes the instrument’s unique Sensor_ID, the Sensor_Type as well as the temperature and displacement data. The balanced differential RS485 output signal used is widely recognized for reliability in harsh environments. The signal can be routinely transmitted over 1,000m/3,000ft of lead-wire.
YieldPoint’s low cost d-Reader readout unit or the new d-TAB. Both provide the temperature and displacement data directly in oC and mm.
Data from the d-Exto can be collected using YieldPoint’s d-Logger dataloggers (d1Logger and d4Logger). Data can be download by any computer device running Windows including the convenient d-TAB.
Automated data retrieval:
Clusters of instruments (4 per Logger) that are monitored using YieldPoint’s d4Logger can be wireless networked using:
- dMesh: a 900MHz wireless mesh solution.
- IoT GateWay if Ethernet is available
