Application
Reference
Production line or QA testing of electric devices
The simultaneous measurement of power consumption parameters such as U, I, P, frequency, power factor and harmonics for production line or QA testing results in reduced tact times. Thus testing is faster and low cost. The DA output and communication interfaces enable data to be remotely and flexibly captured. *“Modbus/TCP” function is supplied with the Ethernet (/C7 option). Evaluation of large current equipment
The WT310EH allows 40 Arms to be directly connected to the input without the requirement to use current clamps or current sensors. This not only provides more precise measurement but also saves on investment costs.The wide current ranges are from 1 A to 40 A and voltage ranges are from 15 V to 600 V. Users can use it to evaluate special waveform driven devices such as, IH cookers and heaters Duration testing and efficiency measurement for industrial motors and rotating machinery
The WT300E series provides reliable current integration (Ah) and Energy (Wh) measurements for up to 10,000 hours. The D/A option can be used to transmit these measurements to an external data logger or recorder, such as a ScopeCorder, and monitor and log data along with other parameters, such as temperatures, torque, and rotation speed. The Modbus/TCP communication with /C7 option is used to save and monitor the measurement results of up 200 chs. YOKOGAWA GA10 data logging software can be used directly to save data along with other parameters such as temperatures, torque and rotation speed by this Modbus/TCP Protocol. |
Development and evaluation tool for home appliances
Automotive- Battery or DC driven device evaluation
Conformance and evaluation testing of uninterruptable power supplies (UPS)
The WT300E series enables users to conduct conformity tests according to UPS performance testing standards. The WT300E series is used to measure and calculate input & output levels, efficiency, frequency and THD. The average active power data also provides accurate values of power consumption. This equipment along with the WTViewerFreePlus software helps to simultaneously measure all necessary parameters required to test a UPS, thereby reducing the evaluation time. |

Optional
WT300E Series
Connectivity of Modbus/TCP*1 with YOKOGAWA’s recorders and Ethernet*1 with PLC Measured digital data of the WT series can be acquired by YOKOGAWA’s recorder GP10*2, *3 and GM*2, *3 via Ethernet or Modbus/TCP directly. It is possible to make use of the GA10*2 data logging software. And also, it can be connected with YOKOGAWA’s PLC, FA-M3V*2 by VXI-11 protocol for production fields. (*1) /C7 Ethernet option is required. (*2) GP10/GM/GA10/FA-M3V are manufactured by Yokogawa Electric Corporation. (*3) /E2 and /MC options are required A wide range of communication interfaces USB, GP-IB or RS-232 (selectable), Ethernet (optional) Users therefore have the flexibility to choose according to their application needs e.g. from production lines to engineering test benches.
Users can use WTViewerFreePlus software to set up all kinds of measurements. Additionally, the numeric values, waveform display* and trend graphs of the measurement data can be displayed and saved. *Waveform display requires the /G5 Harmonic option |
D/A output for measurement recording The D/A option is used to output voltage, current, power and other measured data for recording to data loggers (±5 Vdc outputs). (WT310E/WT310EH 4 CH, WT332E/ WT333E 12 CH) . . Current Sensor Input Users can select either an /EX1 input option (2.5 to 10 V) or an /EX2 (50 mV to 2 V) for measuring large currents using current clamps or current sensors with voltage outputs.
.Comparator Function The WT300E series outputs +5 V, 0 V, or −5 V. To replace the output with a relay contact output, like the WT210/WT230 comparator function, a user can implement their own relay and driving circuit. .Automatic zero adjustment The WT300E series compensates for any drift in the zero level by automatically performing a zero adjustment when the input ranges are changed. This is achieved in less than 100 ms and does not require disconnecting wires. . |
