How hot does the Entry sensor get?

Why is my Entry sensor 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 fixed or mounted devices, the exterior surface temperature limit is 140ºF (60ºC). We routinely test our Entry sensors 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 sensor is safe to touch, even after it’s powered and operational, but it may be uncomfortable to hold for an extended period of time. If you need to move the Entry sensor 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 Entry sensor 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. A minimum 3-inch clearance above the sensor is required for normal operating temperatures, as well as optimal performance.
  • Entry Sensors should not be operated for an extended period while sitting face down on a surface. If the sensor 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 Entry in an indoor, temperature-controlled environment.
