Digital Panel Meters
Digital panel meters are precision instruments designed to display measurements from various analog inputs such as voltage, current, frequency, or process signals. The panel-mounted devices have LED displays that afford clear and precise readability, and they find their applications mainly in laboratories and an array of industrial settings. Digital panel meters accept as their inputs data from load cells or signals from various kinds of processes. They furnish essential real-time feedback for the kind of close monitoring that typifies most system performance applications.
High-performance digital panel meters frequently incorporate relay outputs and screw terminals from which to make secure and efficient connections, allowing the meter to serve "control" functions in addition to serving as a means to measure and display data. Using relay outputs, the panel meter can activate alarms or switch equipment on and off in accordance with pre-set measurement thresholds. These outputs can be used in most applications in which a display and a measurement threshold are needed, from lab settings to industrial environments.
More Information about Digital Panel Meters
Digital panel meters also offer a variety of ways to install the meter and supply power to it, meaning they fit easily into almost any existing setup. You can find them with an input and output configuration to measure just about anything—DC current, for instance, or process signals like temperature and flow. Robust designs mean that even the most demanding process environments can't shake their basic ability to display data accurately.
FAQs
Can digital panel meters use pulse inputs and serial data to process values?
Yes, digital panel meters can use pulse inputs and serial data to process and display values accurately.
HMI vs OIT, What's the Difference
Human Machine Interface (HMI) is a software interface that allows operators to interact with various pieces of electrical hardware and controls systems. HMI typically utilizes monitors or screens to display information, which are referred to as HMI screens. The screens are not the actual HMI, but are a tool used to display HMI software. For example, electrical enclosures often have screens mounted on the outside of them to provide users with information about ongoing process and to allow users to make changes to the system.
Operator Interface Terminal (OIT) typically displays basic information about the electrical hardware that it is attached to. It provides only local information about the environment it is interfacing with and allows control and monitoring for that one piece of hardware, not an entire system.
