Description

The ADS-261 is a battery-powered end node for collecting and transmitting data from bridge strain gauge sensors. It offers a high accuracy bridge instrumentation amplifier input, 1 digital input configurable as a pulse counter input, and multiple excitation options with voltage calibration for powering transducers. The bridge amplifier offers low Input Offset Voltage and low Input Voltage Noise with several gain options are available to meet specific custom applications. The ADS-261 wireless sensor platform provides a smart end node that sends data via the Sigfox network. It offers reliable communication and outdoor enclosures to satisfy a variety of measurement and monitoring applications. SIGFOX, which uses Ultra Narrow Band (UNB) radio technology operating in the license-free ISM radio bands, has the advantage of covering larger areas than other fixed local systems. The D-size Lithium Thionyl battery can provide autonomous operation for over 10 years.

Applications Include:

  • Structural Engineering
  • Water/Wastewater
  • Oil & Gas

We also carry the ADS-260 wireless end node for collecting and transmitting data from analog and SDI-12 or Modbus serial sensors.
