Yokogawa Introduces the Latest Release of the Paperless Recorders and Data Acquisition System

Yokogawa Electric Corporation announced that it will introduce release 4 of the Smartdac+ GX series panel-mount paperless recorder, GP series portable paperless recorder, and GM series data acquisition system on May 19. With this latest release, new modules are provided that expand the range of applications possible with Smartdac+ systems and improve user convenience. New functions include sampling intervals as short as 1 millisecond and the control and monitoring of up to 20 loops.

The functional enhancements available with release 4 are as follows:

1. High-speed analog input module for high-speed sampling

   To improve the safety of electric devices such as the rechargeable batteries used in everything from automobiles to mobile devices, evaluation tests must be run to acquire and analyze detailed performance data. For this purpose, sampling at intervals as short as 1 millisecond is desirable. However, this normally requires an expensive, high-performance measuring instrument. When the new high-speed analog input module available with release 4 is mounted, a Smartdac+ system can sample data at intervals as brief as 1 millisecond, which is 1/100th that of any preceding Yokogawa product. This is suitable for such high performance applications as the measurement of the transient current in rechargeable batteries and vibration in power plant turbines. A dual interval function has also been added that enables the Smartdac+ to efficiently and simultaneously collect data on slowly changing signals (e.g., temperature) and quickly changing signals (e.g., pressure and vibration).

2. PID control module

   In applications that need both control and recording, such as controlling the temperature of an industrial furnace or the dosage process at a water treatment plant, there is a need for systems that do not require engineering and can be quickly and easily introduced. To control temperature, flow rate, and pressure, it used to be necessary to use a recorder and a controller for each control loop, or to engineer a solution that combined a recorder with a programmable controller or touch panel display. When the new PID control module available with this release is mounted, the Smartdac+ can control and monitor up to 20 loops. With the GX and GP series recorders, an intuitive touch panel user interface and screens for the monitoring and operation of temperature and flow rate are available. In addition, web functionality that is a standard feature on all GX and GP recorders allows for remote monitoring and control via a web browser.

3. Four-wire RTD/resistance module for precise temperature measurement

   While three-wire resistance temperature detectors (RTDs) are widely used in many fields, research institutes and manufacturers of products, such as air-conditioning equipment, require the higher level of precision possible with 4-wire RTDs. To satisfy this need, Yokogawa has released a 4-wire RTD/resistance module for the Smartdac+.
