Relative pressure and temperature sensor
Water level sensor for groundwater data monitoringCNRT sensor Integrated the atmospheric pressure aerator

Relative pressure sensors & temperature CNRT

  • Double output signal, level and temperature
  • Measuring range of level 5, 10, 20 mH2O
  • Temperature measuring range of 0°C…60℃
  • Quick connection by connector M12 8Pts to data loggers LOGV4 by 4-20 mA
  • Battery powered logger, low power consumption, autonomy > 5 years
  • Rugged and compact
  • Integrated atmospheric pressure aerator
  • Wireless configuration by short range radio
  • Communication (depending on the logger model) : radio / GSM / GPRS / 2G / 4G
  • IP68 housing protection

Pressure level sensors also providing temperature (Pt1000). Easy to install with their 4-20mA output, and M12 8PTS connectors to the LOG V4 dataloggers. Data retrieval is done by radio on-site, or remotely by GSM/GPRS for compatible loggers.
