Digital Telemeter
Model:
MRS-100 Series
Maker:
Kyowa Electronic Instruments
Features
• Easy operation without PC after initial setting
• Quarter-bridge 2-wire system, 3-wire system, and full-bridge system support
• Up to 64 channels in a system
• Certified in radio law in Japan, the USA, China, India, Thailand, Taiwan, EU (Depends on models)

Application
The MRS-100 Series is a lineup of small wireless units that enable to achieve stable communication with digital modulation, and this series can be used to easily make a strain-gage sensor or voltage-output sensor wireless. The MRS-100 Series can therefore be used to respond to rapid events in the automobile-related and other experiment and research fields, and the testing data can be sent almost in real-time. In addition, because the unit can be incorporated into a production line to make the load, pressure, and other sensors used for quality control wireless, it is useful for improving productivity.
