RY-CZS / 485 tubular noise sensor (outdoor) is an on-line noise monitoring sensor in current environmental monitoring, with built-in high sensitivity sensor and data acquisition module, integrating measurement and transmission. The sensor can also be connected with the dust detector and become a part of the dust detector to measure the noise related data of the tested environment. The noise monitor with industrial standard output (RS485) realizes the real-time monitoring of the field noise with high precision and versatility.

The choice of installation location. This product can be installed indoors or outdoors, in areas with good lightning protection measures, and away from high-voltage electrical equipment.

Output cable. This sensor is led by an aviation plug with a four-core cable. Users can match a cable of appropriate length according to their needs. The cable specification is a 0.2mm² four-core shielded cable. The wiring color is defined as:

Digital quantity output color definition
Red	Power positive
Black	Power negative
Yellow	A
Blue	B

After fixing this product on the mounting frame, test whether the data collection is normal. If it is not normal, please check whether the cable plug is well connected.

Matters needing attention and daily maintenance:

After unpacking, please check whether the product is consistent with your order requirements, and whether the packaging and product are damaged. If you find any errors, please contact our company.

Please connect correctly according to the requirements in this manual.

Hot plugging is prohibited when using this product.

This product is a precision measuring instrument. It is strictly forbidden to smash, impact, forcefully clamp, disassemble, or poke the pressure hole or metal diaphragm with a sharp instrument.

The wires of this product should not be laid together with high-voltage cables.

If it is installed outdoors, please use a clean, dry soft cloth to wipe the windproof ball outside the instrument at intervals.

Please do not input power exceeding the maximum input power of the device, otherwise it will cause damage to the instrument.

It is recommended to return to the factory for measurement calibration once a year to ensure the measurement accuracy of the sensor.
