CRY2100 series noise sensor is a new type of noise sensor for industrial applications. Products execute IEC61672 class1/2 and GB/T3785 class1/2. CRY2100 series noise sensor has a tiny structure and is equipped with a precision measurement microphone which guarantees good temperature and humidity characteristics. The noise sensor which integrates with the signal conditioning circuit and the DSP chip can provide a dynamic range up to 110dB, and measure ambient noises as low as 25 dBA. The noise sensor also has an RS-485 bus interface which can support Modbus RTU protocol and a 4-20mA analog signal output port.
