Why is my device warm?

The sensor is typically a bit warmer than room temperature, but at certain times can reach as high as 135ºF (57ºC) when it is doing a lot of processing or when the ambient environment is especially warm, (80ºF+). Normal operating temperature is between 115ºF - 125ºF (46ºC - 52ºC), which falls within industry and certification standards.

Density sensors are in compliance with industry requirements around temperature for their use-case. For devices that are fixed or mounted use, the exterior surface temperature limit is 140ºF (60ºC). We routinely test our devices for compliance using a FLIR (Forward-Looking Infrared) camera and thermocouples to ensure they never reach the temperature limit under multiple test scenarios.

I have to move my device, is it safe to touch?

The device is safe to touch, even after its powered and operational, but may be uncomfortable to hold for an extended period of time. If you need to move the device after it’s been online, we recommend unplugging the device and waiting a few minutes to cool down, or wearing gloves so it’s more comfortable to hold the device for an extended period.

What can I do to avoid the device becoming too hot?

  • Remove the plastic protector over the vent on the back of the device to ensure proper airflow.
  • Make sure the unit has sufficient clearance, per our installation recommendations.
  • Units should not be operated for an extended period while sitting face down on a surface. If the unit is under heavy load for initial power on or testing and left sitting on a surface (not mounted above a doorway), temperatures will rise as airflow is restricted. 
  • Deploy Density in an indoor, temperature-controlled environment.
