PR300 is a panel-mounted meter designed to meet two user needs: a power facility meter and a meter for monitoring energy consumption.
Combine three desired measurement items and show them all at once on the large LED display. Just one PR300 unit can take the place of two or more meters, dramatically contributing to savings in cost, space and wiring.
PR300 comes with measurement functions for reactive power, apparent power, demand current, demand power, and other items, as well as with a transducer function.
* Use SEL key to view phase Amps and Volts.
PR300 versatilely supports a wide range of phases and wire systems, from a single-phase two-wire system to a three-phase four-wire system. The phase and/or wire system, including CT/VT ratios, can be selected or changed on site using the panel keys. For panel mounting, PR300 supports various standards with different shapes and sizes.
Other RS-485 devices can be connected to the network using Ethernet–serial gateway function.
PR300 comes complete with functions necessary for efficient power monitoring, including power integration over a desired period, a transducer function (4 to 20 mA DC output), an integrated pulse output of electric energy, demand current/power alarm output functions, RS-485 communication (Modbus/PC link), and Ethernet communication.
The Ethernet-serial gateway function enables connection between the PR300 and RS-485 devices.
Data logging by MW100
Monitoring is assisted by the browser, and data are transferred by the FTP function.
Capable of measuring energy and environmental factors
Connection with control devices is possible via the network (10BASE-T/100BASE-TX). Data logging is performed by PC.

The Japan Steel Works, LTD., Muroran Plant uses the Control and Measurement Station CX2000, UP series program controllers, and UT series digital indicating controllers for operation of its heat treating furnaces. The Japan Steel Works (JSW), LTD., Muroran Plant is located in an industrial area looking over Muroran port in Muroran City, Hokkaido.
Okinawa Cellular Telephone Company has launched an experimental vegetable factory to encourage farmers in the prefecture to enter into that business. The 80 square meter vegetable factory engages in hydroponics, and uses 100% artificial lighting. Located at Nanjo City in the southern part of Okinawa island, the facility holds six levels of beds dedicated to raising greens like romaine and leaf lettuce.
A major soft drink manufacturer dictates strict quality control standards to companies that manufacture vending machines, coolers, and dispensing equipment that handle the branded products of the company. The company operates an engineering lab at corporate headquarters in Atlanta where numerous environmental rooms can simulate any climate condition where a vending machine or cooler may operate.
Improving manufacturing efficiency demands constant action - from uncovering operational waste to identifying areas for continuous improvement. Namely, we must always pursue a cycle of visualizing, analyzing, and solving energy saving challenges.
Appliance testing typically require 100% quality check prior to shipping. Early life cycle test and outgoing quality check is instrumental in measuring the product's power consumption, heat dissipation, cabin temperature and safety. The test parameters must be logged and analyzed to ensure the product performs to the quality standards.
Facing serious environmental problems for the whole earth, clean energy using solar, wind, geothermal, tidal, etc... to reduce CO2 emissions is an inevitable matter. Renewable energy providers need economical/reliable/efficient solutions. Yokogawa provides a reliable data acquisition system with high accuracy for measurement and control instruments.
Data from tests of multiple compressors run in parallel are saved to separate files for each compressor using the DAQWORX software suite.
Yokogawa Power Monitors measure energy in plants, such as power, current, voltage, power factor, etc. In addition, data acquisition for power, vapor, fuel, water, air, etc, and data monitoring using viewer software, are performed by connecting to the MW100 data acquisition unit.
A useful pre-shipment inspection for picking out defective items. Measures product watt hours, power, current, voltage, and other parameters before and after general inspection to check for abnormalities.
It's easy to set up a monitoring system for power equipment that saves energy.
Recent years have witnessed increasing corporate initiatives for energy savings and environmental protection due to laws and other ordinances, and this has affected power monitoring needs. As opposed to power monitoring on a large scale such as on the level of an entire factory, there are more and more examples of small scale power monitoring systems such as for manufacturing lines, or even for specific manufacturing equipment.
In order to save energy and reduce rounds made for periodic inspections, you can set up acquisition and monitoring of power data and temperature data from converters, alarms warning against imminent shutoffs due to power overages, abnormal temperature alarms, and other mechanisms.
A large OEM parts supplier to the automotive industry has been a Yokogawa customer for several years. In the past, Yokogawa sold the customer field instruments and data logging equipment for measuring and recording environmental conditions within their facility.
Power generator parameters and weather environment data at wind-farms can be recorded. Remote access allows users to monitor all data for operational status.
