Process display/ panel meters

Process displays are devices that display information about the current status of a process. They can come in various forms, such as a digital display, an analog scale or an LED display. Process indicators are used to display the current value of a physical parameter or a measured variable in a process, such as temperature, pressure, flow rate or fill level.

Panel meters are special measuring devices that are installed in devices or systems in industrial or technical applications. They are normally integrated directly into the process and measure one or more measured variables continuously or periodically. Built-in measuring devices can be temperature sensors, pressure transmitters or flow meters, for example. They are used to monitor the status of the process, record measurement data and, if necessary, make adjustments or controls in the system.

There are various types of process indicators and panel meters that are used in industrial plants to monitor and control processes. Here are some examples:

1. Digital displays: This type of display shows the current measured value in digital form. You can display various units such as temperature, pressure, flow rate, etc. Digital displays use sensors to capture the measured value and then convert it into digital signals that are shown on the display.

2. Analog displays: Analog displays use pointers or bars to indicate the measured value. They are usually provided with a scale that represents the measuring range. Analog displays are often used for pressure and temperature measurements. They are based on mechanical or electronic sensors that record the measured value and convert it into a mechanical movement that moves the pointer.

3. Touchscreen displays: This type of display enables interactive operation and display of process data. They use a touch-sensitive screen on which various measured values and control options can be displayed. Touchscreen displays can be configured for different applications and often offer advanced features such as trend graphs, alarms and logging.

4. Built-in measuring devices: Panel meters are specially developed for installation in control cabinets or housings. They are compact and offer easy integration into existing systems. Panel meters can monitor various measured variables, such as temperature, humidity, pressure, flow rate, etc. They are often used in industrial processes to monitor the operating status and trigger alarms if certain limit values are exceeded.

The exact functionality of the process indicators and panel meters depends on the respective type and model. In general, sensors record the process variables, convert them into electrical signals and pass them on to the display or measuring device. The device then processes the signals and shows the measured value on the display. Depending on the model and configuration, process indicators and panel meters can also offer additional functions such as alarms, data logging and communication with other devices.
