New PPC-3 portable power monitor
Vydas introduce new portable power monitor for machine analysis and process development
VYDAS International Marketing have announced the release of a new portable power monitor manufactured by Load Controls Inc. in the US.
The PPC-3 portable power monitor offers accurate and extremely fast (15ms) true power measurement for machine analysis or process development, giving process engineers the flexibility to assess the performance of individual machines and product processes.
The instrument has been designed to complement the company’s range of power cell transducers, which are now firmly established with process control customers who require the 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 and cannot provide accurate measurements under such conditions.
The PPC-3 power monitor is mounted in a rugged, easy-to-carry waterproof case. A digital true power display calibrated in horsepower or kilowatts is included, with peak emphasis to allow 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 the stirrer or paddle drives, even minute viscosity changes can be detected.
