CRY2120 Noise sensor
CRY2120 Noise sensor is small and has integrated signal conditioning, amplification, sampling and computation circuits. It provides industrial universal RS-485 communication interface / 4-20 mA analog output / Modbus and other data transmission modes.
-
Wide dynamic range
-
Small figure
-
High industrial compatibility
Features of CRY2120
Small volume, stainless steel case, and excellent corrosion resistance
Equipped with precision measurement microphone, internal integrated preamplifier, high precision ADC, and high speed DSP processor
Excellent performance with 110 dB dynamic range, able to measure the noises as low as 25 dBA
Supporting SPL Lxy measurement, X supports A, C, Z frequency weighting modes, y supports F, and S indicates the time weighting mode
Support 1/3 octave analysis
The device uses RS485 bus and our customized communication protocol for data communication, and another version that supports Modbus RTU Communication Protocol is optional.
The products of this series have been widely used in the detection, monitoring and evaluation of noises generated by machinery and equipment, traffic trunks, industrial enterprises, construction sites, and community living environment, etc.
