THE MARKET for data acquisition (DAQ) boards, modules and software is poised to expand to nearly $1 billion by 2009, according to analysis from Frost & Sullivan. Sales will reach $823.3 million, with the data acquisition modules market alone expected to grow at an annual rate of 13.4% during this period.
On the Ethernet front, the market also has seen considerable growth in distributed DAQ applications. Market analysis provided by Venture Development Corp. shows revenues from distributed DAQ applications constituted approximately 20% of the total DAQ market’s revenues in 2005, and they continue to find increased acceptance.
While demand for data acquisition systems, data loggers and recorders continues to grow at an accelerated pace, our rundown of new systems and devices for industrial processing applications shows technological advances are keeping up with how DAQ is being used by controls and instrumentation engineers.
Systems and devices used to measure acoustics, vibration, shock and other signals are now available with thousands of I/O channels. Many new devices now can be mixed and matched, mostly for applications that demand a variety of industrial measurements with full isolation.
Advances in data recorders include adoption of wider bandwidths for data-collection. New data loggers have gone ultra-compact and include internal sensors as a second temperature channel.
USB-based, Ethernet-based and data-logging DAQ devices with out-of-the-box functionality are the latest in PC-based data acquisition. Many new devices support Modbus and TCP protocols, enabling communication with third-party software drivers and HMI/SCADA packages. In addition, distributed I/O is being used more often to collect data from remote sensors and other instrumentation, and to provide process control and distributed I/O capabilities.
Data Acquisition Devices
DAQ System Supports Modbus
isoLynx SLX200 data acquisition system enables communication with third-party software drivers and HMI/SCADA packages. The fully isolated DAQ can interface with more than 650 analog I/O modules for factory automation, process control, test and measurement, machine control and data acquisition applications. Communication protocol is Modbus RTU for RS-232/485 or Modbus TCP for Ethernet. Standard communication is RS-232/485. Dataforth; 800/444-7644; www.dataforth.com ;
Paperless Recorder Improves Display

iBTHX transmitter lets you monitor and record barometric pressure, temperature, relative humidity and dew point over an Ethernet network or the Internet by using a Web browser. No special software is required. The transmitter serves active web pages to display real-time readings; charts of barometric pressure, temperature and humidity; and logged data in standard formats for use in a data acquisition program, spreadsheet, or programming language. Features include a probe that measures barometric pressure, temperature, humidity and dew point in a single location. Omega Engineering; 203/359-1660; www.omega.com
Distributed Graphic Recorder
6000XIO distributed graphic recorder views and archives data, remotely, from various operator displays in a plant. The recorder has an intuitive, touch-screen display to enable operators to view process data in varying format; onboard Flash data storage capability; Ethernet communication; a Compact Flash Card; and access via a local-area network, dial-up connection, intranet or Internet. Data is stored in a tamper-resistant binary format that can be used for secure, long-term records of your process. Eurotherm; 281-296-7114; www.eurotherm.com
Pluggable Wiring for Bus Terminal I/O
KS Series bus terminal I/O system includes pluggable connections from the face of the I/O housing without the need for tools. The connector can be removed from the bus terminal assembly by pressing an unlocking tab. Users insert the new I/O component and replug the connector in with the wiring. Bus terminals from the KL and KS series can be mixed and matched on the same I/O node without restrictions. Beckhoff Automation; 952/890-0000; www.beckhoffautomation.com
