Noise meter system, measures 30-130 dB with 4-20 mA output and Class 2 calibrator (94/104/114 dB)

The decibel meter consists of a measuring microphone with handle and a wall holder with 1.5 m cable, a noise transmitter and a digital display. The main application of the noise meter is the continuous noise measurement and noise monitoring of factory halls, production rooms and large events (discotheques, folk festivals, kart tracks, etc.). The digital display has a relay output for the control of alarm horns or blinkers for visual or acoustic warning and a control output. The limit value for this alarm output can be programmed on the display. The analogue output signal can also be used for controlling window flaps ... or the signals of the transmitter can be stored, evaluated and documented on a logger. The noise warning device is very easy to connect and can be operated via 240 V power adapter. The cabling is the only installation task that the customer has to carry out himself. Thus, this noise warning device can be used quickly for monitoring purposes.
