Wireless Data Recording System Wireless Controller ZT-120
The wireless data recording system consists of the wireless module ZT-014 and the wireless controller ZT-120.
The wireless module incorporates an A/D converter that converts measurement data from strain gage transducers into digital data for interval measurement, data recording, and monitoring. Since wiring from the sensor to the controller can be made wireless, it is ideal for measurement in locations where wiring of measurement cables is difficult or detracts from the landscape, or for measurement of moving objects, reducing wiring labor and costs.
Measurement data is stored in the memory of the wireless module, and the wireless controller and PC are brought in periodically to collect the data.
- Features
- Communication distance is approximately 50m in line-of-sight
- Wireless controller is connected to PC via USB and powered by USB bus power
- Up to 20 wireless modules can be controlled (setting, data collection, monitoring)
