Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
58 words
An ambient compensated solar sensor comprising a support, a pair of matched thermal sensors mounted on said support in fixed widely spaced thermally insulated relation to substantially prevent heat transfer between said thermal sensors, and a shield surrounding and protecting from solar radiation one of the matched thermal sensors, the other of said matched thermal sensors being unshielded.
Claim 2
Dependent Claim
58 words
An ambient compensated solar sensor comprising a support, a pair of matched thermal sensors mounted on said support in fixed widely spaced thermally insulated relation to substantially prevent heat transfer between said thermal sensors, and a shield surrounding and protecting from solar radiation one of the matched thermal sensors, the other of said matched thermal sensors being unshielded.
Claim 3
Dependent Claim
22 words
A solar sensor according to claim 1 additionally comprising transparent enclosures for each of said thermal sensors, said enclosures being substantially identical.
Claim 4
Dependent Claim
21 words
A solar sensor according to claim 2 wherein a thermally conductive potting compound embeds said thermal sensors within the respective enclosures.
Claim 5
Dependent Claim
31 words
A solar sensor according to claim 1 further comprising an insulating member, said thermal sensors mounted on opposite ends of said insulating member, and said support joined to the insulating member.
Claim 6
Dependent Claim
17 words
A solar sensor according to claim 4 wherein said insulating member and said support form a tee.
Claim 7
Dependent Claim
14 words
A solar sensor according to claim 5 wherein said tee is made of plastics.
Claim 8
Dependent Claim
13 words
A solar sensor according to claim 5 wherein said tee comprises tubular construction.
Claim 9
Dependent Claim
27 words
A solar sensor according to claim 7 additionally comprising leads connected to the respective thermal sensors and passing through said tee for connection to an external circuit.
Claim 10
Dependent Claim
15 words
A solar sensor according to claim 1 wherein said thermal sensors are thermal sensitive resistances.
