      Mounting the sensor
      All mounting options for your sensor can be found in the Sensolus product mounting instructions.
      Mounting the probe
      This is a lab product. The optimal mounting instruction for the probe is still being investigated. At this moment there are no
      standardized instructions to mount the probe since this is use case specific.
      Testing the sensor before actual usage is required.
      Mounting advice for liquid containers
      You will need quality thermal paste to mount the probe onto the liquid container.

      Step
      Action
      Details
      Locate the thermal stud
      Find the stud on the liquids container
      There is a stud with external thread on the
      liquids container. Loosen the nut. The
      thermal probe of the SENSE T 4004 should
      be attached onto the stud.
      Mount the probe
      Apply thermal paste and attach
      Apply enough thermal paste onto the sensor
      probe and attach to the stud. Screw the nut
      back onto the stud. Make sure everything is
      fastened tightly together.
      Mount the sensor
      Position the sensor correctly
      Mount the sensor in the tank shell, with the
      probe behind the insulation and the sensor
      as close as possible to the external cover to
      ensure BLE connection to a tracker. Fit outer
      insulation, making sure the pocket is well
      insulated. Do not use too much insulation.
      Close up everything.
      Locate the thermal stud
