Noise Measuring Sensor for Smart Cities
TA120

Noise has become an essential vector when sensing smart cities. CESVA’s more than 45 years of experience designing and manufacturing sound level meters are concentrated in the TA120 noise measuring sensor.
The TA120 combines the accuracy of a Class 1 sound level meter, maximum protection of a professional outdoor kit (rain, snow, wind, dust, birds, IP65), and full connectivity with major open source platforms and industrial protocols into one small-sized single piece of equipment.
The TA120 requires minimal annual maintenance and can be verified with an acoustic calibrator (IEC 60942). The TA120 offers you high precision and reliable noise measurements.
Description Specifications

Product Full Description

The TA120 brings together in a small-sized single piece of equipment, the accuracy of a Class 1 sound level meter, maximum protection of a professional outdoor kit (rain, snow, wind, dust, birds, IP65), and full connectivity with major open source platforms and industrial protocols.

The TA120 requires minimal annual maintenance and can be verified with an acoustic calibrator (IEC 60942). The TA120 offers you high precision and reliable noise measurements.

    Road and port infrastructures
    Industrial activities
    Separate waste collection routes
    Control of Works
  • Noise monitoring:
    Concerts, festivals, major events and exhibitions
    Sports events and racetracks
    Quiet areas (acoustically protected)
  • Generating noise maps and displaying in real time noise levels

Features:

  • Class 1 precision sensor according to IEC 61672-1.
  • Protection against external agents with an outdoor kit: wind, rain and birds. Keeps class 1 precision. IP65 protection.
  • Can be fully integrated into different platforms: NoisePlatform (CESVA), open source ones such as Sentilo or proprietary platforms like Telefónica or Smarty Planet.
  • Light weighted small sized and easy to install in street lights, marquees, billboards, shelters, kiosks and advertising posts.
  • Powered by mains, POE (Power over Ethernet), 12 VDC (Solar panels*, external batteries).
  • Continuous measurement 24 h/7 days a week.
  • Minimum annual maintenance. Materials used in the manufacture of TA120 ensure a long life.
  • Removable outdoor kit for quick verification and adjustment with an acoustic calibrator (IEC 60942).
  • Network with an unlimited number of sensors.
  • Communication by Ethernet (RJ45), Wi-Fi*, 2G/ GPRS or 3G modem*, 4-20 mA loop*.
