Abstract
A viscosity measuring instrument for measuring ceramic slurries, e.g. in a casting tank, with a probe having an elbow and presenting a transducer part in substantial alignment with a flow direction of the ceramic slurry relative to the active part and a barrier orthogonal to such relative movement direction is interposed in front of the transducer part by one or more stand-off rods to form a partial enclosure that moderates flow to the active part and provides a long term stable measuring capability.
Claims5
A viscosity measuring instrument for use in measurement of viscosity of ceramic slurries comprising:
- means defining an instrument with a transducer portion constructed and arranged for immersion into and movement within a vessel containing the slurry to present a portion of the transducer in substantially linear opposition to movement relative to the slurry for a continuous time range of contact and positioned to block direct flow of the slurry at the transducer along the direction of rotating movement of slurry,
- the transducer being of a linear form substantially aligned with the direction of relative movement, and
- means defining a barrier substantially orthogonal to the direction of relative movement, the barrier being held out from the transducer by one or more stand-off parts, the combination of barrier and stand-off being constructed and arranged to effect a tortuous path of slurry to the transducer and limit build up of coating on the transducer end.
