Abstract
A temperature probe, such as for a respiratory system in which breathable gases are supplied to a patient, includes a housing having an external wall and an internal cavity defining an end and an internal cavity and further includes a temperature-responsive device in an area of the cavity near the end, such as in thermal communication with the external wall. A first potting compound that is deformable and/or has a relatively high thermal conductivity holds the temperature-responsive device in the cavity and a second potting compound having a relatively low thermal conductivity may be in the cavity behind the first potting compound. The housing may be made thin to enhance thermal conductivity, at least in the area containing the temperature-responsive device.
