Abstract

A standard industrial temperature gauge is adapted for a sanitary conduit that has been provided with a tubular stub for mounting the temperature gauge. A disk flange mates with an upper flange of the tubular stub. A aperture or passageway in the disk flange permits the rod probe of the temperature sensor to penetrate through it. An O-ring seal seated within the passageway seals against the rod probe. A female threaded nipple is affixed on the flange disk coaxial with the passageway. This nipple has threads to mate with the male threaded stem of the temperature gauge. A sealing gland or equivalent seal is disposed between the disk flange and the flange of the said tubular stub, so that the sanitary conduit is sealed off when a clamp is installed, removably holding the flange disk in sealed engagement with the tubular stub.

Claims

1. Temperature gauge adapter for use in connection with a sanitary conduit through which a liquid product flows whose temperature is to be monitored, the conduit including a tubular stub formed on said conduit to mount a temperature gauge and to permit a cylindrical rod probe of the temperature gauge to contact said fluid;

and wherein said temperature gauge has a body portion and a male threaded stem from which said rod probe extends;

the adapter comprising;

a flange member of a diameter to mate with an upper flange of said tubular stub;

seal means disposed between said flange member and the flange of said tubular stub;

clamp means for removably holding said flange member in sealed engagement with said tubular stub;

a passageway formed in said flange member of a sufficient diameter to permit the rod probe of the temperature sensor to penetrate therethrough;

an O-ring seal seated within said passageway for sealably engaging said rod probe when the latter penetrates said passageway;

a female threaded nipple affixed on said flange member and coaxial with said passageway, and having threads to mate with the male threaded stem of said temperature gauge.

2. The temperature gauge adapter of claim 1 wherein said flange member includes a disk flange having a radially tapered outer edge adapted to receive a tri-clamp.

3. The temperature gauge adapter of claim 1 wherein said threaded stem has a diameter of about ¼

inch, and said female threaded nipple has a matching inside diameter.

4. The temperature gauge adapter of claim 1 wherein said passageway and said nipple are centrally disposed on said flange member.
