The Logix® 520MD digital positioner is a highly efficient device that provides superior positioning and tuning functions for valves and actuators. With its easy setup and powerful diagnostic tools, this positioner is ideal for a wide range of industrial applications.
What sets the Logix 520MD positioner apart is its multi-variable gain tuning algorithm which allows for precise control of valve and actuator movement. The positioner can make large step changes with minimal overshoot while achieving the resolution to respond to very small step changes.
The Auto-tune procedure is another powerful feature of the Logix 520MD. This function cycles the actuator to produce a measured response and selects gain values that provide appropriate actuator performance. With the gain modifier selector, users can increase or decrease the calculated gain in order to achieve optimal performance.
Configuration of the Logix 520MD positioner is a breeze, thanks to its easy DIP switch configuration for tuning mode and other common settings. Users can also modify tuning sets with a handheld device or with ValveSight™ software, to accommodate a wide range of actuator sizes and types.
Configuring a system can be a challenging task, but it doesn't have to be with our efficient and straightforward configuration features. Commissioning your system is easy and quick, and our fast configuration process ensures that you get your system up and running in no time.
Calibrating and tuning your system is an essential step in ensuring its optimal performance. With our self-calibration and auto-tune features, you can improve your system's performance and keep it running at peak efficiency. You can also adjust your gain selector to optimize your system for the specific application you are working on.
Industry standards matter, and that's why our system is equipped with HART communications that are widely used across industries. This standardization ensures that you can easily integrate our system into your existing setup and enjoy seamless communication between devices and control systems.
By using low air consumption in our system, we ensure that we meet the sustainability goals of reducing energy consumption and minimizing waste. With our low air consumption feature, you can be sure that your system is eco-friendly and cost-effective.
The two-stage control design in our system ensures faster response times and tighter control. With this feature, you can be sure that your system will respond quickly and accurately to changes in the process, giving you more control over your operations.
ValveSight™ software is a standard diagnostic tool that comes with our system. With this diagnostic functionality, you can easily troubleshoot your system and identify any issues that may arise. The ValveSight™ software also allows for predictive maintenance, which can help you prevent potential issues and ensure that your system runs smoothly.

Power generation is an essential aspect of modern life, and there are multiple methods to produce electricity. A conventional steam power plant generates electricity through the use of burning fossil fuels to create steam, which then drives turbines. Combined cycle plants use the steam produced to turn turbines and also use gas turbines, allowing for higher efficiency. Concentrated solar power (CSP) generates electricity through the use of mirrors or lenses to concentrate and direct sunlight to heat up a fluid, which then drives turbines. Biomass and municipal solid waste (MSW) power plants use organic waste as fuel to generate electricity. Finally, geothermal plants use heat from the earth to generate electricity.
The chemical industry is vast and varied, producing a wide range of products from basic inorganic and organic chemicals to specialty fine and consumer chemicals. Biofuels are produced from biomass, which are renewable organic materials such as plants, algae, and waste. Pharmaceuticals are chemicals used for medical purposes, and petrochemicals are chemicals derived from oil and natural gas.
Water management is crucial for ensuring that water is being used effectively and efficiently. Wastewater must be treated before being released back into the environment, and agriculture and irrigation require careful water management to ensure optimal growth. Flood control systems are designed to minimize the damage caused by floods.
The oil and gas industry involves upstream exploration and production, midstream transportation, and downstream processing. Upstream exploration and production involves finding and extracting crude oil and natural gas from the earth. Midstream transportation moves oil and gas through pipelines or vessels to refineries for processing. Downstream processing involves refining oil and gas into usable products such as gasoline, diesel, and heating oil.
General industries include pulp and paper production, steel and primary metals manufacturing, food and beverage production, corn wet milling and ethanol production, and other industries. Mining involves the extraction of minerals from the earth.
