Introduction
Sigfox has a global coverage network, operating in unlicensed bands worldwide, with radio frequencies ranging from 862 to 928 MHz. Using unlicensed bands enable devices to send their data to the cloud while using little power, at very low cost.
ADS-261 is a battery powered Sigfox end node for strain gage bridge sensors. The unit is available for the RC1 (868 to 869 MHz), RC2 and RC4 (902 to 928 MHz) bands. The unit incorporates one Bridge Amplifier input, one digital input configurable as pulse counter input and multiple excitation options for powering transducers. A D-size Lithium Thionyl battery can provide autonomous operation for over 10 years.
Measurement
ADS-261 incorporates a high precision Bridge Amplifier (Instrumentation Amplifier) with low Input Offset Voltage and low Input Voltage Noise. Several gain options are available to meet specific custom applications.
Transducer excitation
The unit provides multiple excitation options with voltage calibration for measuring transducers.
Applications
- Structural Engineering
- Water/wastewater
- Oil & Gas
