Safety Transmitters For Temperature and Pressure

Series One Safety Transmitter
United Electric Controls
Industrial history is replete with examples of catastrophic accidents. New safety technologies exist today that can prevent or mitigate mishap and disaster in fluid processing and other operations. Modern philosophy of plant safety brings a focus on a proactive approach. Process operators have a new sense of urgency to bring increased levels of safety to their operations.

The United Electric Controls (UE) Series One is a SIL-certified (Safety Integrity Level) transmitter designed solely for safety, alarm, and shutdown. With reliability, speed, and reduced nuisance trips an integral part of its design, the Series One is suitable for application in new installations, or easily integrated into existing operations.

A typical safety loop consists of sensors (such as a pressure or temperature transmitter), controllers, and final control elements. Most SIL-rated pressure transmitters require 300ms to communicate with the controller, then up to 500ms for the controller to send a signal to the final control element (such as a valve). This combined response time may insufficient for some applications. Incorporating the One Series Safety Transmitter, directly connected to the final control element, the total signal time is reduced to 100ms - a large and significant time savings when safe operating conditions have been breached. When used with blowers, pumps and compressors, the One Series makes up a complete safety system with a self-contained sensor, controller, and final control element (the switch) capable of SIL2 without additional safety instrumented function (SIF) components.

The below document provides detailed information about the Series One. Share your process safety challenges with the instrumentation specialists and combine your process knowledge with their product application expertise to produce effective solutions.

Opportunity For Improving Power Plant Heat Rate

Opportunities for improving efficiency at power plants
The large scale of most power plants provides a environment in which financial justification, or payback, of attempts to improve energy consumption can be justified. Even small improvements in efficiency can yield very substantial returns. The challenge to engineering and management is to select the projects which have the best overall probability of success and can be integrated into the process with the least amount of disturbance.

One area of the steam cycle that may be a candidate for improvement is the feedwater heater. This device is essentially a shell and tube heat exchanger used to recover waste heat from the process and use it to preheat boiler feedwater. Maintaining the correct liquid level in the feedwater heater is a key element of extracting maximum performance. Magnetrol, a globally recognized leader in the development of level measurement equipment, has produced a video showing how their technology can be used in an advantageous manner to others in regulating feedwater heater liquid level and achieving maximum efficiency.

Measurement of pH/ORP is a common operation throughout a number of industries. Obtaining true measurements and making correct interpretation of the results can prove challenging without solid working knowledge of the methodology and procedure involved. Certain effects have the ability to cause problems if not taken into consideration.

The book provided below, authored and provided by Yokogawa Electric Corporation, provides a comprehensive understanding of pH/ORP measurement and how to achieve reliable results. Basic information on the principles of measuring pH/ORP, construction of the sensing elements, and their basic use in process applications is provided.

A part of achieving accurate and reliable pH/ORP measurements includes the provision of sufficient electrode strorage conditions and proper maintenance. Prevention of common errors during maintenance and storage, as well as consistent detection of loop failures is important. This book describes how to avoid pitfalls and detect failures.

The book is accompanied with a frequently asked question and answer section as well as an appendix that includes helpful information like a Chemical Compatibility Table and a Liquid-Application-Data-Sheet, which can be used to describe the user’s application.

Safety Transmitters Achieve Safety Goals With Reduced Cost and Complexity

Series One Safety Transmitter
United Electric Controls
Process safety experts continually seek sustainable ways to improve the performance of safety critical loops, achieving risk reduction and safety goals in a cost-effective manner. Some view a reduction in complexity of safety related protocols to be a positive development. Traditional or historical approaches to deploying full blown safety systems were generally associated with great expense and high complexity, and still came up short on delivering the needed levels of risk reduction. Process control device and equipment manufacturers have responded with newer technologies and products that better address the safety needs of industrial processing.

In sensor subsystems, United Electric’s certified safety transmitter for pressure or temperature provides a less costly, simple path for process designers, instrument and control engineers, and maintenance personnel. The Series One Safety Transmitters combine several useful safety and monitoring functions into a single, easy to deploy device. Products are available for gauge pressure, differential pressure, and temperature applications. In addition to a 4-20 mA process variable output, the Series One has an embedded programmable high-capacity relay certified as a safety variable output. The Series One Safety Transmitter provides designers the option of a hard wired trip in less than 100 milliseconds, with a tenth of a percent repeatability, along with the monitoring functions of a traditional continuous analog output.

For equipment under control requiring protection, or processes where rapid excursions can initiate dangerous events, this unique pressure and temperature transmitter is addressing process safety time constraints, coupling issues with PLC and DCS units, and adding diversity to the safety instrumented function.

There is a whole lot more to learn about these "Safety right out of the box" industrial pressure and temperature safety transmitters. A product data sheet is provided below, but you can get the latest and most detailed product and application information from a specialist in industrial process measurement and control. Share your safety instrumentation challenges with them, combining your process expertise with their product application knowledge to develop effective solutions.

Yokogawa Data Acquisition Unit Product Changes

data acquisition units for process control and automation
The DX1000 and DX2000 are among the potential
replacements for the discontinued CX Series
Modern industrial process control has ever increasing demands for data acquisition. The ability to rapidly gather and process measurements into control and management decisions and reports is essential to efficiency, safety, and profitability. Yokogawa has been a leading manufacturer in the data acquisition sphere for decades, and has made some changes in its product line to maintain its leadership position.

The model CX 2000 was discontinued at the end of February. It combined data acquisition, display, control, and networking in a single unit. A scaled down version, CX 1000 was previously discontinued. The company recommends possible replacements to include one or more of the following products:

  • Advanced Application Temperature Controller UT75A
  • Button Operated DX1000/DX2000
