Wireless Data Acquisition System
Wireless module ZT-014 / Wireless Controller ZT-120
The wireless data acquisition system consists of wireless module ZT-014 and wireless controller Z_T-120. The wireless module incorporates an A/D converter which digitize the measured data of strain-gauge-based transducers and carries out interval measurement, data acquisition and monitoring. Since no wiring between the sensor and controller is needed, the system is optimal for measurement in a place where cable arrangement is very difficult or the scenery is destroyed and on moving test specimen. You can save troublesome wiring and cost. The measured data are stored in the memory of the module and periodically collected by the controller and PC.
Features
- Easy wiring due to wireless.
- Noise-resistive as digital process is done near strain gauges.
- Very low power consumption Possible one year or more measurement.
- About 50m in communication distance with an open view
- Small and light wireless module
- USB connection of wireless control and PC and USB bus power driving
- Capable of controlling wireless modules of the maximum 100 units for setting, data collection and monitoring.
Application Examples
| Data on the inclination of a retaining wall (with inclinometers), the tensile force of an anchor (with annular load cells) and the behavior of an observation well (with water-level meters) are collected wireless in site. |
