Abstract: A combination temperature and low water sensor includes a body configured to penetrate the wall of a hydronic furnace. A detection tip is attached to the body and extends into the furnace when the temperature sensor penetrates the wall. The detection tip is electrically conductive and defines a tip interior volume. A temperature sensor is disposed within the interior volume of the detection tip. Both the detection tip and the temperature sensor are configured for electrical connection to a furnace control system.

Abstract: A duct averaging sensor has a plurality of sensor elements contained within a housing. A housing connector selectably joins the housing to a mating terminal connector. The terminal connector may be attached to the outside wall of a duct. The housing connector and terminal connector may be selectably attached and detached, with the housing extending into the inside of the duct. The selectable attachment of the housing to the terminal connector substantially eases installation and maintenance of the duct averaging sensor over prior art duct averaging sensors.

Abstract: A temperature probe having a terminal attachment arrangement for securing and selectively releasing an electrical connection is disclosed. The temperature probe further includes a housing for sealing the temperature probe to a structure, such as a HVAC duct.
