Application

Tips: How Does Stainless Steel Noise Sensor Work?

The noise detection sensor is made of advanced stainless steel and works via RS485 communication technology. The principle is based on a highly sensitive sound sensing device that is capable of monitoring the sound level in the environment in real time.

When the noise in the environment exceeds a set threshold, the noise sensor will send a digital signal through the communication interface to the monitoring system. The monitoring system can analyze the noise level in real time through these data and implement corresponding control or alarm.

This structure can be widely used in urban environment monitoring, industrial place safety and other fields, providing reliable technical support for effective management and improvement of noise environment.

how convert to 4-20?

If the default communication is RS485, how can I change it to signal 4-20?

ATO Responded

You can only determine the output signal type before purchasing. If you choose RS485, it cannot be changed to 4-20mA.

I have some questions

I had about Noise Sensor, Stainless Steel, RS485. What the meantime to failure for this product? We do not need data logging. Can you confirm that it does not have this feature? It looks like the product comes with an L-mount bracket. Can we obtain a Y-mount bracket instead? This product will be in high humidity environment. Confirming that it can withstand harsh environments?

ATO Responded

1. Under normal use, the product has a lifespan of 8-10 years.
2. The sensor does Not have a data recording function, and the data is only output via RS485.
3. The Y-type bracket requires you to provide us with a dimensional drawing or similar physical photos to confirm the style so that we can confirm whether it can be implemented.
4. The sensor can meet the IP67 dust and water resistance standard.

Great Product-Great Price

Super fast shipping and item works as described, Recommended!
