Abstract: A noncontact distance measuring sensor and a method for noncontact distance measurement is provided. The distance measuring sensor has a coil arrangement including at least two measuring coils oriented along a common axis. An electrically and/or magnetically conducting measurement object is in electromagnetic interaction with the coil arrangement. The distance measuring sensor further has an evaluation circuit for evaluating and ascertaining a position of the measurement object. In addition to the measuring coils, the noncontact distance measuring sensor includes an additional coil which is arranged along the common axis, is coupled to the evaluation circuit, and at least partly overlaps at least one of the two measuring coils.

Abstract: A portable gas transfer device for point-of-use sterilization at a sterilization site includes: a housing; a pressurized gas canister held by the housing; a first passageway in fluid communication with the pressurized gas canister and configured to supply pressurized pre-sterilization gas from the pressurized gas canister to the site; a gas discharge canister held by the housing; and a second passageway in fluid communication with the gas discharge canister and configured to supply post-sterilization gas from the site to the gas discharge canister. Additional related devices, systems and methods are provided.
