Abstract
An improvement to bimetallic pipe thermometers utilizing insulating tubular seats. The present invention improves the insulating tubular seat by closing off the tail slot along a proximal end thereof with a bridge or stop. Going forward, users of such bimetallic pipe thermometers no longer need worry about the tail of the bimetallic coil sensor unintentionally slipping out of what is currently an opened-ended tail slot.
Claims11
A method of improving a bimetallic pipe thermometer utilizing a tubular seat with an open-ended tail slot that extends longitudinally along a sidewall of the tubular seat, wherein the bimetallic pipe thermometer comprises a bimetallic coil sensor configured to convert temperature change to vertical mechanical displacement of a tail of the bimetallic coil sensor, the method comprising:
- calibrating the bimetallic coil sensor by confining said tail in said open-ended tail slot until it is finally calibrated;
- and
- closing off a proximal end of the open-ended tail slot with a stop.
A tubular insulating seat for housing a bimetallic coil sensor with an unrestrained tail, the tubular insulating seat comprising:
- a longitudinal slot extending along a non-rotatable sidewall of the tubular insulating seat to just inward of a proximal edge of the tubular insulating seat so that the unrestrained tail protrudes through the longitudinal slot, wherein the unrestrained tail has a known calibration when protruding through the longitudinal slot;
- and
- a bridge at a proximal end of the longitudinal slot to separate the longitudinal slot from said proximal edge of the tubular insulating seat, preventing loss of the known calibration caused by the unrestrained tail vacating the longitudinal slot.
