专利汇可以提供Electronic hook gauge manometer专利检索，专利查询，专利分析的服务。并且A hook gauge manometer provided with a micrometer mounted probe incorporated in an electrical circuit in which a pen light cell provides a direct current power source, with the direct current from the power source being electronically converted to provide an alternating current signal that is transmitted through the gauge liquid when the hook gauge probe is moved to its read out position, with the alternating current signal being electronically converted to a direct current signal that is sensed by a direct current detector and provides a visible signal that the instrument is to be read. The unit is portable and measures positive, negative, or differential pressures in the zero to two inches water column range.，下面是Electronic hook gauge manometer专利的具体信息内容。

权利要求

1. A hook gauge comprising: a body formed with a pair of upright well chambers in open communication adjacent their bases and adapted to receive a quantity of gauge liquid, said body being U-shaped in configuration and defining a pair of upright spaced apart legs in which the respective chambers are formed and that define a housing mounting space therebetween, said body being mounted on a base plate, means for leveling said base plate, a high pressure connection fitting for one of said chambers, a low pressure connection fitting for the other of said chambers, a probe positioned in said other chamber, means for mounting said probe for movement longitudinally of said other chamber including micrometer means for measuring said movement of said probe, a housing mounted in said mounting space between said body legs, said housing including cell means providing a source of direct current power and means for converting direct current from said source to an alternating current signal, said probe being incorporated in a circuit which includes contact means disposed to be in electrical conducting relation with the gauge liquid when the latter is in said chambers, means in said housing for applying said alternating current signal to said circuit, means in said housing for converting the alternating current signal, when transmitted through the gauge liquid on contact of said probe therewith, to a direct current signal, a direct current detector mounted in said housing, and means in said housing for making said detector responsive to said direct current signal whereby said detector indicates contact of said probe with the gauge liquid in said chamber.

2. The hook gauge set forth in claim 1 wherein: said housing is releasably clamped against said body on either side thereof tO secure same to said body.

3. The hook gauge set forth in claim 1 wherein said circuit includes: a first length of electrically conductive stripping secured to said body and extending between said probe and said housing mounting space, a second length of electrically conductive stripping secured to said body and extending between said contact means and said housing mounting space, said housing including electrically conductive contacts resiliently biased against the respective strippings at said mounting space to electrically connect same in said circuit.

4. The hook gauge set forth in claim 1 wherein: gauge liquid is disposed in said well chambers and comprising distilled water containing coloring and a wetting agent.

5. The hook gauge set forth in claim 1 wherein: said detector includes an indicator arm visible from one side of said gauge, said base plate including a pair of adjustable support legs at either end thereof at said one side of said gauge for leveling said gauge, said base plate being supported along the other side of said gauge by a single leg, and wherein said base plate includes spirit level means adjacent said detector.
