Panel Meters - Accessories - LXPPM000 application field and working principle

LXPPM000 series panel meters are an essential part of multiple systems, especially alarm systems. To be specific, when the system is in an ideal state, an indicator shows no indication, like a warning light stays off. When a problem is detected by sensing conditions, the panel will be activated, like a warning light turns on. To ensure its accurate functioning, it is important to have a clear knowledge of its application fields, installation, and working principle.

Application Fields

LXPPM000 series panel meters are mainly utilized for analog Signal monitoring. It is suitable for both linear and logarithmic signals. Thus, they are installed in control systems, amplifiers, and industrial process control systems. Panel meters are also applied to take readings in car engines, such as fuel injection, voltage, and temperature.

Installation

For successful installation of the panel meters, various conditions must be meticulously checked beforehand. First and foremost, it is important to make sure that the installation sites are adequately sheltered from vibration, dust, humidity and oil. Appropriate protection should be applied in the entrance and exit to the panel. Additionally, the panel meter should be polarized properly such that it functions correctly after installation.

Working Principle

Once installed, it is time to take a closer look at the working principle of the panel meter. Generally, LXPPM000 series panel meters measure electric signals such as current and voltage, then convert them into an observable value shown on the interface. This conversion process is mainly facilitated by electronically controlled circuit, analog amplifier, and a controller.

To come to the conversion, a controller obtains input signals through a surrounding coupling transformer, then derive control signals from these signals. These control signals are then used to regulate the current via a controlled circuit, thereby adjusting the parameters of the analog amplifier and generating a voltage reading displayed on the interface. Accordingly, this reading denotes the measured current, voltage, or temperature.

Conclusion

To sum up, LXPPM000 series panel meters play a significant role in the measurement of current, voltage, or temperature in a wide variety of systems. Installation of the panel is a simple yet delicate task, while understanding its working principle will help to maximize its efficiency. Therefore, it is important to be aware of the application fields, proper installation, and working principle of LXPPM000 series panel meters.
