A print liquid supply unit, comprising:
- an electrical interconnect sealed in a supply joint and extending through the supply joint from an outside of the supply unit to an inside of the supply unit, wherein the supply joint is welded to join housing components of the supply unit.
A print liquid container, comprising:
- a container property sensor including a strain sensor or pressure sensor connected to a container wall;
- and
- a conductor coupled to the container property sensor that is sealed through a welded joint of container shells.
A method, comprising:
- installing an electrical conductor in a print liquid container lid, wherein the electrical conductor is coupled to a digital liquid level sensor and a strain sensor or pressure sensor, and wherein the electrical conductor is covered with a flexible protective layer;
- and
- welding the print liquid container lid to a print liquid container body, wherein the electrical conductor is situated in a joint between the print liquid container lid and the print liquid container body.
