Mounting a sensor - Amazon Monitron

Mounting a sensor

The temperature and vibration detectors are located on the base of the Amazon Monitron sensors. Any area of the base is effective as a target contact area, but the contact area must be at least 30 x 25 mm for reliable detection. Center the target contact area over the mounting location for the most reliable results. The circular aluminum sensor (in the center of the target contact area) conducts heat directly from the asset's surface to the temperate sensing mechanism inside the Amazon Monitron sensor.


See the Monitron Sensor Device Safety and Compliance Guide before installing and using sensors.

Determine the place and orientation where you can most effectively monitor the asset, and then mount sensor at that spot. To mount the sensor, you need to purchase an industrial adhesive. We recommend using cyanoacrylate epoxies like Loctite 454 and Loctite 3090 or something similar. If the surface on which you mount the sensor is flat and relatively smooth, only a thin layer of adhesive such as Loctite 454 is needed. If the surface is rounded or somewhat uneven, apply a slightly thicker layer of adhesive such as Loctite 3090.

If you are uncertain of where to mount your sensor, see Positioning a sensor.


When installing sensors, check and obey applicable safety regulations. You are solely responsible for safely installing the sensor on any equipment or machine part. To mount a sensor, you use industrial adhesive. Always consult and obey the adhesive manufacturer's safety and handling instructions.

For more information about the recommended adhesive, see Loctite 454 Technical Information or Loctite 3090 Technical Information, as appropriate.

To mount a sensor
  1. Remove all oil and grease from the position on the asset where you want to mount the sensor.

  2. If the surface that you're mounting the sensor to is flat and relatively smooth, apply a thin layer of adhesive such as Loctite 454 to the bottom of the sensor, maximizing the area that will be in contact with the asset.

    If the surface is rounded or somewhat uneven, apply a slightly more liberal layer of adhesive such as Loctite 3090 to the bottom of the sensor. The layer of adhesive can bridge distances of up to 5 mm between the surface and the sensor if necessary.

  3. Hold the sensor to the mounting location on the machine part for 30 seconds, pressing firmly.

    If you're mounting the sensor on a curved surface, put a small amount of additional adhesive on each side for better contact between the sensor and the surface. Based on the surface and the adhesive used, your results should look similar to the following.
