Chapter 2 General device description 5
This chapter provides a general description of the TA120 noise sensor. This
description will introduce you to all the possibilities offered by the TA120 and its
main features. It will also help you to identify the various components of the device.
2.1 TA120 noise sensor
The TA120 sensor is the solution for monitoring noise levels of infrastructures and
activities. The TA120 brings in a small size equipment, the Class 1 sound level
meter precision, the maximum protection of TK200 a professional outdoorkit (rain,
snow, wind, dust, birds, IP65) and full connectivity with open source platforms and
industrial protocols.
2.2 Main features of TA120 sensor
The most important features of TA120 sensor are as follows:
•Class 1 precision sensor according to IEC 61672-1.
•Protection against external agents with outdoor kit TK120: wind, rain, birds.
Maintains Class 1. IP65 Protection.
•Can be fully integrated into different open source platforms for sensors
connectivity.
•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 (optional PS120 Solar
panel kit, external batteries), public lighting network with optional BA120 daily
backup battery*.
•Continuous measurement 24 hours / 7 days a week.
•Minimum annual maintenance. The materials used in manufacturing the TA120
ensure a long life.
•Removable outdoor kit for quick verification and adjustment with an acoustic
calibrator (IEC 60942).
•Communication by Ethernet (RJ45) or other options: 3G/GPRS Modem, Wi-Fi,
Current loop (4-20 mA loop).
