SENSECOM-HPNC

Product detailed description

Remote transmission device for vibrating wire (VW) /resonant sensor using a nationwide LPWAN IoT network NB-IoT. 

•  Input from resonant / vibrating wire (VW) sensor
  • Multichannel unit for 2 VW sensors, expandable to 8 VW sensors 
    • String oscillation period measurement
    • Thermistor measurement
• Requires 1-2 SENSECOM-HPNCM extension modules for more than 2 VW channels , each HPNCM module supports 3 VW extra channels
• Applicable for VW-type geotechnical and structure diagnostic sensors:
  • Pressure/piezometers (pore pressure, soil moisture and water levels)
  • Strain Gauges
  • Load & Pressure Cells
  • Displacements
  • Crackmeters
  • Extensometers
  • In Place Inclinometers
  • Tiltmeters
  • External Temperature
• Operating with VW instruments/sensors from producers like:
  • DGSI (Nova Metrix),
  • Encardio,
  • Geosense,
  • Geokon,
  • Gloetzl,
  • Innovative Geo-technical Instrumentation,
  • Pizzi instruments,
  • Roctest (Nova Metrix),
  • RST Instruments (Terra Insights),
  • SISGEO,
  • Soil Instruments (Nova Metrix),
  • Systel instrumentation, etc.
• Measured string frequency range 600Hz - 5kHz
• Resolution and accuracy:
  • Within range 600-1500Hz, Accuracy: 0.009 %, Resolution: 0,002Hz
  • Within range 1500-3000Hz, Accuracy: 0.011 %, Resolution: 0,004Hz
  • Within range 3000-5000Hz, Accuracy: 0.010 %, Resolution: 0,006Hz
  • The accuracy of the measurement is usually limited by the accuracy of the VW sensor itself and its calibration capability.
• Built-in sensors:
  • atmospheric pressure
  • temperature
  • relative humidity
  • detection of condensed water
  • accelerometer
• Memory (datalogger) for least 1500 measurements
• E2E encryption with AES-256 possible
• > 10 years without battery replacement with 2 transmissions and 2-12 measurements a day
• SMA connector for external antenna, select optional external antenna or use other antenna (suitable for NB-IoT band)
• IP67 protection
• Communication to the nationwide IoT network NB-IoT, Select whether to include an NB-IoT SIM card with 10 years flat rate with coverage type.
• Select optional multi-user multi-year flat rate for SENSEPARAM portal to access processed data, sending callbacks to your server, etc. or process data directly from NB-IoT UDP packets.
