Transient recorder system combines high channel density and high-precision measurements

Recorder from Elsys Instruments offers 64 channels with flexible configuration for a variety of industrial applications.


Transient recorder from Elsys Instruments offers 64 channels with flexible configuration for a variety of industrial applications.Elsys Instruments, a manufacturer of precision data acquisition systems, now offers the TraNET EPC, a complete transient recorder that provides up to 64 channels in one system. The new unit combines Elsys' family of high-speed LAN-controlled instruments featuring multiple acquisition modes with a series of robust industrial computers designed for high-precision measurements in industrial environments.

The flexible TraNET EPC enables configurations designed to users' unique measurement needs, making it ideal for a diverse range of power measurement applications, including verification and testing of  electrical engine control systems, inverters, frequency converters, power plant maintenance, and particle accelerator control. The unit's LAN connectivity allows standalone operation, so TraNET EPC can reliably be deployed in mobile and remote environments as well.

The unit can be equipped with up to 16 of Elsys' TPCX PCI-compatible digitizer modules that feature typical measurement precision of ±0.03%, sample rates up to 240 MS/s at a vertical resolution of 14 bits (up to 30 MS/s at 16 bits), and acquisition memories up to 128 M points per channel.

Available in 8-, 16-, 24-, 32-, 48- and 64-channel versions, the scalable design allows units to be coupled and synchronized for clock-and-trigger with the Sync-Link Box for up to 512 parallel channels. Using TransAS 3 software, TraNET EPC becomes a turnkey solution enables both quick configuration of acquisition channels as well as a post-processing analysis of complex waveforms. In addition, two entirely separate instrument functions can run on a single EPC backplane using TransAS 3.

Using a sophisticated data acquisition mode, event controlled recording (ECR) is ideal for troubleshooting and long term monitoring applications. ECR mode requires a trigger event, but eliminates the dead time between triggers using an overlapping technique of adjacent acquisitions. In addition, every channel can acquire waveform data independently on trigger command as well as synchronously with associated channels. The time-stamped events are recorded first in the onboard memory using a ring-buffer architecture, and are then written to the internal hard drive. As long as the streaming rate keeps up with the data trigger rate, this mode can run until the hard drive is full.

Annual Salary Survey

After almost a decade of uncertainty, the confidence of plant floor managers is soaring. Even with a number of challenges and while implementing new technologies, there is a renewed sense of optimism among plant managers about their business and their future.

The respondents to the 2014 Plant Engineering Salary Survey come from throughout the U.S. and serve a variety of industries, but they are uniform in their optimism about manufacturing. This year’s survey found 79% consider manufacturing a secure career. That’s up from 75% in 2013 and significantly higher than the 63% figure when Plant Engineering first started asking that question a decade ago.
