Pid computer

Types of PID computers

A PID computer has different kinds for various business uses. One is the portable PID, which is light and small. Users can carry it wherever they need to work, so it is very convenient. Another kind is the fixed PID. It is too big to carry about, but it has features that make it work well. Some features are more stable and consistently accurate data. Most industrial applications that use PID controllers prefer this kind because of those features.

Some PIDs can move between different places in a laboratory or industrial area. They are not as strong as fixed PIDs, but they still do their job well. Then, we have the ATEX certified PID computers. They are in a special explosion-proof design. PIDs with this certification are safe to use in places with highly dangerous explosions.

PID computers come with different displays. The handheld ones have 4 to 5-inch displays. But then again, some displays are brighter and sharper than others. They are easier to see in the sun or very bright areas. Some PID computers have displays with touchscreens. The touchscreens are easier to use than displays with just buttons. Then we have PIDs with displays that are 7 inches or larger. Users can see the data better on bigger screens than on smaller ones.

A few more types of PID computers have special capabilities. Some can connect to printers, while others can connect to smartphones and tablets. There are also PIDs that can connect to data loggers. These computers can export the data they gather into printed paper or another device.

Functions & Features of PID Computer

  The data gathering and analysis capabilities of PID computers are essential for optimizing processes and making informed decisions. It systematically collects a wide range of process-related data over time. This aids in the identification of patterns, trends, and anomalies in the data, which improves process performance, efficiency, and troubleshooting. PID computers ensure smooth and effective industrial operations by continuously monitoring and analyzing critical data.

• Sequential Control:

  Sequential control is essential in many industrial applications, such as machine automation and production processes. Some PID computers have sequential control capabilities that allow them to manage multiple devices and processes in a predetermined sequence. This function improves operational efficiency and consistency by automating various tasks and operations.

• Enhanced Control:

  A PID controller with computer capabilities has advanced control features that enhance regulating complex processes. This might incorporate functions like multi-loop control, where several parameters are being controlled simultaneously, or cascade control, for example, that links multiple controllers for better precision and stability.

• Data Logging and Reporting:

  The functions of a PID computer include data logging and reporting, which are crucial for maintaining compliance and making informed decisions. Data logging allows for the continuous recording of historical data related to critical process parameters over time. This historical data can be used for analysis and investigation, assisting operators in understanding process behavior, finding recurring problems, and taking corrective action as necessary.

• Alarm Management:

  The alarm management features for PID computers are important for ensuring safe and effective industrial operations. Alarms and alerts are generated when deviations from normal operating conditions occur or critical thresholds are reached.

• Networking and Connectivity:

  Networking and connectivity are important functions of PID computers because they enable effective data exchange and integration in industrial settings. PID computers can connect to other devices, systems, and networks through various communication protocols and interfaces.

• User Interface and Customization:

  The user interface (UI) and customization options of PID computers are essential features that allow operators to interact with the system easily and tailor it to their specific needs. A user-friendly interface with clear visualizations, such as graphs, charts, and trend displays, is critical for monitoring process parameters in real-time and making informed decisions.

• Integration with Other Systems:

  Integration with other systems is a key function of PID computers that enhances operational efficiency and data management. PID computers can connect and exchange information with various systems, such as manufacturing execution systems (MES), enterprise resource planning (ERP) systems, and distributed control systems (DCS).

How to choose pid computers

When choosing a Pike's Peak PID computer, buyers must remember specific factors that could differ based on preferences and requirements.

• Scaled Channel Count:

  The scaled channel count is the total number of input channels for which the output is being multiplied or divided. For instance, a PID controller with a scaled channel count of 2 means there are 2 control outputs, but only one set of control inputs for each control output. This factor brings consistency to applications where control inputs are to be shared among control outputs. Buyers can choose a PID controller with a scaled channel count that meets the requirements of their application.

• Number of Outputs:

  The number of outputs varies in different PID controllers. While some have two outputs, others can have up to eight. The type of controller chosen should depend on the nature of the application. Controllers with more outputs are mainly used in applications that require multiple control actions for effective process management.

• Input Type:

  PID controllers are devices that take different kinds of signals from different types of sensors in systems and use them to control the process. This equipment includes a controller that can accept signals from sensors with different input types like digital, analog, voltage, and current. The input type of a PID controller can significantly impact its capabilities. For example, a PID controller with analog input can only regulate a process variable that can be measured by a sensor that provides an analog signal.

• Output Type:

  The output type of a PID controller depends on its application. For example, the output type can be voltage or current. Voltage output can control devices that accept a variable voltage signal, like a control valve with a pneumatic actuator. Current output, on the other hand, can control devices that require a variable current signal.

• Power Supply:

  When selecting the power supply of a PID controller, the needs of the application must be considered. For instance, a PID controller with a power supply of 24 VDC can be used in systems that operate on a low DC voltage.

• Number of Inputs:

  The number of inputs varies based on different model types. While some PID computers have two inputs, others can have up to eight. The specific requirements of the application will determine the number of inputs to look for when choosing a PID computer.

• Display:

  Display is an essential function of a PID controller used to monitor process variable. The display type can either be LED or LCD. A PID controller with an LCD display is preferred over one with an LED display because of its higher resolution and color depth. An LCD can clearly show details about the controlled process, like temperature, control settings, and alarm conditions.
