Panel meters are an important component of most automated systems, providing crucial information about the performance of the system as a whole. Counters, hour meters, and other panel meters are used to measure the amount of energy produced by a given system or device, as well as the amount of time a particular system or device has been in use. In this article, we\'ll discuss the application field and working principle of 98755-100 panel meter.

Application Field

The 98755-100 panel meter is designed for use in industrial equipment such as power supplies, electric motors, and other heavy duty equipment. Its built-in functions make it suitable for applications where adjustable timing and measuring are required. Some of these applications are as follows:

• Measurement of AC/DC electric parameters.
• Counting of engineering or production cycles.
• Start/stop/reset timing and measuring.
• Primary current and voltage monitoring.
• Time interval recording.
• Time signature: digital or analog output.

Working Principle

The 98755-100 panel meter is an active digital device that operates on the principle of electronic counter circuits. It works by counting the incoming pulsed signal continuously. It is composed of two stages: a pre-amplifier stage and a counter stage. The pre-amplifier stage is the first stage, which consists of a high-gain amplifier, comparator circuit, and reset circuit. This stage amplifies, eliminates, and compares the input signal, as well as produces the reset signal for the counter stage. The second stage is the counter stage, which consists of several counter scales for measuring time-interval. These scales can be adjusted on a model-by-model basis.

Once the amplified signal is fed into the counter stage, it is converted to an exact number of rotations, indicating the total number of periods of the incoming signal. The number of rotations can then be displayed in the LED panel of the meter or recorded in a memory chip. The recorded information can be used to determine the energy produced, for instance, in an AC generator.

Additionally, the 98755-100 panel meter is also equipped with a variety of alarm functions, allowing users to monitor and adjust the readings of the panel meter remotely. Some of the features include a warning for low or high readings, and an automatic reset feature, allowing the user to make adjustments without the need to manually reset the meter after each measurement is taken.

Conclusion

The 98755-100 panel meter is an advanced digital device that is capable of measuring AC/DC electric parameters, counting of engineering or production cycles, and recording time intervals. Its built-in features, such as alarm functions and automatic reset feature, make it suitable for many industrial applications, such as power supplies, electric motors, and other heavy-duty equipment.
