**Acoustic sensor NM2101**
What we sell is the sensor part.The customer is responsible for understanding the relationship between the ultrasonic waves emitted by the sense object and the state of the object, and for building a processing system for the ultrasonic signals.
## ■ Example of sensor installation
## **・ ・ Installation with adhesive Installation with double-sided tape (Permanent placement) (Temporary installation)**
## **・ Installation with special attachment**
Attachment can be easily detached and attached with a magnet on the surface of the attachment adhesive fixation of the attachment enables measurement in place even when the sensor is detached.
Fixing around the sensor installation surface with specified adhesive.
Double-sided tape is applied to the sound collecting surface of the sensor, which is then affixed to the object and sealed with clay around the installation surface.
