Yokogawa is one of the most trusted names in data loggers and recorders, but the company also develops generic data-acquisition equipment that competes with the big guys (NI, iotech, etc.). Here are some of these products from Yokogawa's current line:

PC-Based Measurement Instruments: WE7000
Yokogawa developed the WE7000 Data Acquisition System based on the following concepts:
- Simple data acquisition without any software development
Each WE7000 system includes the standard control software and each module has its firmware resident within the module.
- Isolation and noise immunity
Isolation and noise immunity are very important for the mechanical electronics area. The WE7000 has great isolation from the base station to the input modules as well as channel to channel (depending on the module) isolation.
- Various precision modules with traceability
WE7000 has various modules from 2 Hz to 1 GS/sec digitizing rates. There are also modules with signal output capability, including a precision D/A and a function generator.
- Remote control and monitoring using Ethernet Communication
WE7000 control, monitoring, and real time saving of data are all available using Ethernet communication. |

Data Acquisition Unit: MW100
The MW100 is a scalable, high performance data acquisition/data-logging platform designed for both PC-controlled and stand-alone operation under harsh operating conditions. Open Ethernet connectivity with web-based configuration and data monitoring functions allow MW100 to handle a wide range of monitoring and historical logging functions. See real time trends with your web browser from any PC and no special software. A full range of input/output modules handle all of your process inputs with fast measurement speed and high noise immunity for rock-solid performance.
Anytime, Anyplace...
- In a wide range of temperatures: -20 to 60° 1,2,3,4
- Reinforced insulation: Between input terminal and case5
3700 Vrms (one minute) or 600 Vrms/VDC (continuous)
- A wide variety of network functions: HTTP, FTP, DHCP, SNTP, E-mail, and others
- DC power supply (12 V-28 V) option available
Smart Logging...
- High speed measurement with a single unit (10 channels/10 ms or 60 channels/100 ms):
Shortest measurement interval of 10 ms
- Multi-interval: Enables mixing of three different measurement intervals in a single unit
(measurement intervals can be set for each module)
- Supports CompactFlash (CF) cards 6 of up to 2 GB
Continuous data acquisition is possible on 60 channels at 100 ms for approximately ten days with a 2-GB card, or for three months on 60 channels at 1 s.
- MATH function on the main module available with the /M1 option.
- Collective data acquisition on 360 channels (via Modbus with the /M1 option)
1. The operating temperature range for the input modules and main module. The operating temperature range of the output modules is -20 to 50°.
2. Note that the power cord supplied with the main module differs depending on the operating temperature range (see the specifications on page 7). If the operating temperature range specification of the supplied standard power cord does not meet your requirements, we recommend that you select a screw-type terminal rather than the plug type for the main module power inlet, and supply your own power input cable.
3. The operating temperature range of the AC adapter used with DC power supplies is 0 to 40°.
4. Please consult with a representative for applications involving temperatures below -20°.
5. The withstand voltage value with the MX110 input module. For the withstand voltage values of other input and output modules, please refer to the specifications for those modules (GS 04M10B01-01E).
6. CF card not included (sold separately). |

Yokogawa's famous DARWIN line has been a staple for the DAQ-using industry for many years.

DAQ Equipment Series: DARWIN
Concept of DARWIN
The name "DARWIN" stands for Data Acquisition and Recording Windows. The equipment is modularized, with the data acquisition engine as the heart of the measurement system, which converts analog signals to digital signals. The series uses various "Window = interfaces", so that the data acquisition environment can be freely configured to ensure expandability; there are no black-box type restrictions. The series is designed to overcome conventional problems and to offer a flexible response to changes in the environment. This ability to evolve with the times makes the series a new standard for data acquisition equipment. |
Equipment in the Darwin series includes the famous DR-series recorders
DR130/ DR230/ DR240
Direct to PC, FDD or Paper Hybrid Recorders
Data Collectors and Loggers may, arguably, be what Yokogawa does best. Here we spotlight some of Yokogawa's top data-collection products:
Data Collectors: DC100
The DC100 features a large display with a whole range of functions, allowing you to monitor data while storing them in memory. With it's sophisticated memory, the DC100 offers simple data acquisition and recording in a single device, yet it's still fully portable and packed with features. No PC needed. No chart paper. No environmental impact. A cost-effective solution to your measurement needs.
* 10 to 300 isolated inputs
* Measurement interval: As low as 0.5 sec.
* Flexible inputs: DC Voltage, Thermocouples, RTDs, mAmps, AC Voltage/Current, Strain, Pulse
* Versatile Memory
* 3.5” FDD std.
* Power Source: 90 to 250 VAC, 10 to 30 VDC (optional)
* Direct PC connection via GPIB, RS-232C or RS-422/485
* Weight: Approx. 10 lbs.
* Flexible Expandability
From 10 to 300 channels, the DC100 can be flexibly modified and expanded. It handles a variety of input signals such as DC voltages, thermocouples, RTDs, contacts, power monitors, pulses, strains, and DC currents (mA).
* Dependable Durability
Durability against harsh environments is assured by Yokogawa's unique technologies such as the planar transformer and high-breakdown-voltage solid-state relay. The DC100 also complies with various international safety standards.
* Effective Data Processing
The various memory functions (memory size: 1, 2, or 4 MB: specified when ordering) allow effective data acquisition and recording. Data can be transferred to a personal computer while making a backup in the memory. The standard features include a 3.5-inch floppy disk drive and DAQ 32 software.
* External Mass Storage Interface (/C5, option)
The external mass storage interface (SCSI) option is a communication interface for saving files created in the DC100 internal RAM to the MO/Zip/Jaz/PD disk.
* Report Function (/M3, option)
Report files can be created hourly, daily, monthly or at designated time/date independently.
* Complete Application Software
In addition to Yokogawa's original software packages such as InTouch for DARWIN and DARWIN DAQ 32, a huge range of software packages for DARWIN as well as driver software such as LabVIEW, and FixDmacs can be used.
