Industrial process measurement and control utilizes transmitters in abundance. There may be instances where, for convenience or due to equipment changes, the output signal from the transmitter will need to be converted to a different protocol or format. Yokogawa has produced an instructional video showing, in a clear and understandable way, how to install a signal converter on their EJX910 Multivariable Transmitter. While the instructional video shows a conversion from Modbus to USB, the knowledge and understanding gathered from the short video will help you to meet other signal conversion challenges that may arise in your facility.
Your investment of five minutes to watch the video will generate returns by increasing your understanding and allowing you to move forward with confidence when a signal conversion task inevitably comes up. More information on signal conversion products, as well as process measurement transmitters, is available from an application specialist. Enlisting their help to generate solutions to your industrial measurement and control requirements is also a good investment of your time.
Density is certainly a fundamental physical attribute of any liquid that is the subject of a process control operation. The ability to accurately measure liquid density in a process application is achievable using specially applied technology from Yokogawa.
The company's latest version, the model DM8, is a vibration type liquid density analyzer with reliable, multi-function operation. It is the culmination of manufacturing and density measurement technology experience extending back over 40 years. The DM8 employs a converter with an incorporated microprocessor to directly convert sensor frequency signals into displayed density values. One touch calibration, internal diagnositics, and digital communications are also provided.
The DM8 liquid density analyzer measures liquid density of general process liquids with high sensitivity and excellent stability. It has a measuring density range of 0 to 2.0 g/cm3, and is unaffected by flow rate and viscosity. Sensor options include general-purpose, sanitary, and explosion proof versions.

Industrial processes often are characterized by substantial hazard through their operation. As operators, engineers, and designers, we are responsible for keeping those actual and potential hazardous conditions and occurrences in check. I recently wrote about safety transmitters that can be used to enhance safe industrial process operation and provide compliance with applicable standards.
I located a single sheet document that summarizes the features, benefits, cost savings, and compliance ratings for the safety transmitters from United Electric. You can get more detailed information on these devices and how to properly apply them in your process control scheme by contacting a product specialist. Combining you process expertise with their product application knowledge will generate a solid solution.
One Series Safety Transmitters Courtesy United Electric Controls
United Electric Controls has developed a safety transmitter that combines transmitter, safety switch, and display gauge in a single, easily deployed device. The One Series Safety Transmitter includes the manufacturer's patented self diagnostics, along with diverse and redundant signal processing that feed algorithms to detect and respond to internal faults and process abnormalities.
The safety transmitter provides a local switch that can be used for rapid emergency shutdown at the point of measurement or detection, eliminating the need to communicate with other safety controllers and await a response. The safety relay output is programmable and can handle high voltages and currents associated with shutting down control valves, compressors, and other industrial equipment.
In addition to the safety relay output, the One Series Safety Transmitter provides logic outputs that can be employed in voting logic schemes often used to produce warnings prior to a shutdown. For reliability, the unit employs no moving parts and includes self diagnostics with a local display of device status.
There is a whole lot more to learn about these "Safety right out of the box" industrial pressure and temperature transmitters. The product brochure 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.

Yokogawa continues to innovate in the industrial process measurement and control field with their TDLS200 Gas Analyzer. Based on tunable diode laser spectroscopy, these industrial instruments offer calibration stability and fast in situ measurement. They can also be applied in a manner that avoids interference from other gases present in the sample. In the company's own words...
The new Yokogawa TruePeak Tunable Diode Laser Spectroscopy (TDLS200) Analyzer is one of the most robust process analyzers available designed to make fast, accurate measurements on near-infrared absorbing gases in harsh process environments, where conditions are of high temperature or pressure, it can be used under difficult conditions including environments involving corrosive, aggressive and high particulate content materials.
The TruePeak Tunable Diode Laser Spectroscopy (TDLS200) Analyzer is ideally suited to in-situ analysis, particularly for measurements in environments involving changing pressure or temperature. It can operate with process pressures up to 20 bar absolute and process temperature up to 1500°C, has a fast response (from 2 to 20 seconds), and is interference-free for most applications.
It can measure Carbon monoxide (CO), from low ppm detection limits to percentage levels at process temperatures of up to 1500°C. The analyzer can also be used for measuring parts per million moisture content in corrosive and aggressive process streams including chlorine and hydrocarbons.
The industrial applications for this technology, integrated into an intuitive and user-friendly equipment package, are extensive. Included below is a white paper authored by the company that explains the operating principles, installation and configuration, and capabilities of the unit. Contact a product specialist about your gas measurement and analysis requirements. See how the capabilities of the TDLS200 can improve your process performance.
Industrial process control implies the presence of industrial process measurement. Throughout our operations, we seek to measure "how much" of something is present. In the case of many materials, weight is the preferred measurement.
Weight is a measurement of force. We can use it as a statement of "how much" because gravity is considered constant across the planet surface. The force I measure for a batch of material in the US will, for commercial purposes, be the same force measured for that material after I ship it to somewhere else. Measurement of weight can be used for establishing proper mixing ratios of components to be combined in a particular manner. The level of material in a tank or other container can be ascertained through a measurement of weight.
In our processes, higher throughput and accuracy are always in demand.
The Vishay Precision Group's BLH/Nobel Weighing Systems operating unit manufactures a high speed, high performance control for industrial weight/force measurement applications. Their G4 line of controllers provides the user a wide range of configurable options, from multiple input channels to analog and digital outputs. The clean user interface provides access to all functions and channels and the unit is available as a freestanding desktop, DIN rail mount, or panel mount unit. There is also a model configured for harsh environments.
The video below provides a good overview of the unit and its potential applications. Contact a product specialist to receive more details, or to discuss how the G4 might be helpful to your process operation.
