A flame sensor apparatus includes a sensor assembly. The sensor assembly includes a photodiode for sensing characteristics of a flame. The photodiode outputs an electrical photocurrent. The sensor assembly includes an electrical assembly that is electrically remote from the sensor assembly. The sensor assembly includes an electric cable assembly extending from the sensor assembly to the electrical assembly. The electric cable assembly includes an electrical cable to electrically convey the photocurrent to the electrical assembly. At least the sensor assembly is configured and constructed to experience and continue to operate at a temperature at or greater than 200&#xb0; C.

High temperature flame sensor

An atomic particle detection assembly includes one or more detectors that detect atomic particles. The detectors are positioned within a first chamber having a first operating pressure. The atomic particle detection assembly includes a junction apparatus supporting the detectors. The junction apparatus defines a second chamber having a second operating pressure that is different from the first operating pressure. Sensing electronics are attached to the detectors and the sensing electronics are housed within the second chamber of the junction apparatus.

Gas-tight packaging of detectors

An electrical system for an atomic particle detection assembly includes an electrical component electrically connected to an atomic particle detection unit. The electrical system includes a dielectric insulating material surrounding the electrical component. The electrical system also includes a conductive shielding material surrounding the dielectric insulating material. The conductive shielding material and a conductive element are at substantially the same electric potential.

High voltage shielding to enable paschen region operation for neutron detection systems

A sensor apparatus is used for sensing a condition in a combustion chamber. The sensor apparatus includes a sensor housing having a sealed internal chamber. The sensor apparatus further includes a connector attached to an opening of the sensor housing. The connector transfers a signal indicative of the condition into the sensor housing. A fastener is secured to the connector. A sealing member is disposed between the connector and the fastener. The sealing member sealingly engages the connector to prevent fluid passage through the connector and into the internal chamber of the sensor housing. A method of sealing a sensor apparatus is also provided.

Hermetic electrically shielded connector

A detector includes an outer shell having a shell profile in which a welded portion of the shell profile extends as an annular flange in an outward direction relative to a center axis of the outer shell. The detector further includes an end cap positioned adjacent the welded portion of the outer shell. The end cap and the welded portion of the outer shell are welded together to form a seal. A method of making a detector is also provided.

Weld joint design for automatic welding of tubular detectors

An atomic particle detection assembly includes at least one detector that detects atomic particles. The atomic particle detection assembly includes a junction apparatus supporting the detector. The junction apparatus includes a first manifold attached to a first housing at an attachment location. The junction apparatus includes a sealing device sealing the first manifold with respect to the first housing along a sealing axis. The sealing axis is substantially parallel to and separated a first distance (d) from an attachment axis defined by the attachment location.

Counterbalanced vacuum seal for neutron detectors

A layered heater structure including an electrode layer and a localized tuning method for tuning the electrode layer of a layered heater structure with high precision is provided. The localized tuning method tunes the electrode layer to its proper local resistance to minimize temperature offsets on the heater surface and thus provide a desired thermal profile that is in marked contrast to conventional, non-localized resistance tuning approaches based on thickness trimming practices, such as grinding or blasting, or resistivity adjustment, such as local heat treatment.
