1 Product Introduction
1.1 General
The MBT-4500 is an in-line viscosity transmitter designed for use in
demanding applications. The transmitter has a wide range of applications and
can be used for measurement of glue, paint, slurries, sugar solutions, oil,
coating mix, food, etc. It is also suitable for use in somewhat abrasive media.
The sensor electronic employs modern microprocessor technology with
advanced signal analysis. It is operated using BTG's electronic platform, the
CPM, which ensures capability with present and future communication
interface requirements, from analogue output with HART®to field buses.
