The instrument has been designed to complement the innovative range of Power Cell transducers, which are now firmly established with process control customers who require the very best possible motor load "process end point" monitoring signal under the most difficult industrial conditions.
Using three clip on "Hall Effect" current sensors, the instrument has a wide frequency response, is not affected by poor wave shape or frequency and is suitable for use on the OUTPUT of variable frequency or inverter drives. Many other power monitors use current transformers (CT's) and can not provide accurate measurements under such conditions.
The PPC3 power monitor is mounted in a rugged easy to carry waterproof case. A bright digital true power display calibrated in Horsepower or Kilowatts is included, with peak emphasis allowing fast moving events to be monitored. Selection switches provide flexible ranges and both 0-10V and 4-20mA isolated analogue outputs allow measurements to be transferred to remote instrumentation, chart recorders, data loggers and computers.
Many industrial process machines such as grinders, mills, mixers, rollers, pumps, compressors, extruders etc may be improved by sensing power instead of just current. Applications include monitoring optimum feed rates, tool condition, mixture viscosity, pump or fan flow, obstructions or overloads.
The PPC-3 Portable Power Monitor and Power Cell transducers are particularly suited to mixer "process end point detection" where by measuring the true power drawn by stirrer or paddle drives, it is sensitive enough to detect minute viscosity changes.
