INTRODUCTION
The Blancett B220210 Magnetic Pick-up with Preamplifi er was designed to directly replace a standard pick-up within a turbine ow meter when signal amplifi cation is required. The pick-up is a combination of a standard Blancett magnetic pick-up and a solid state electronic preamplifi er in a single stainless steel housing.
OPERATING PRINCIPLE
As fl uid fl ows through the meter the turbine rotates at a speed proportional to the fl uid velocity. As each turbine blade passes through the magnetic fi eld at the base of the pickup, an AC voltage pulse is generated in the pick-up coil. The voltage signal generated by these pulses becomes amplifi ed within the pick-up. The output signal generated from the pick-up is now in the form of a square wave. The frequency of this amplifi ed signal is used to represent the fl ow rate of fl uid passing through the turbine fl ow meter.
