Application Field

The AHT3801 Panel Meter is mainly used in industrial applications. As a general-purpose control instrument, it can be used to measure, control, and monitor various parameters. Its main uses include the following:

Measurement of Process Parameters:

AHT3801 is most frequently used to measure and monitor parameters associated with processes such as temperature, pressure, flow, and humidity. It can also be used for other process-related measurements and monitoring, such as the monitoring of power consumption.

Control of Process Parameters:

The AHT3801 can be used to control process parameters during operation, by adjusting settable digital points or parameters. In addition, it can be used to set alarms when critical parameters exceed predetermined thresholds.

Display of Process Parameters:

The AHT3801 can also be used to display process parameters to operators or other personnel in a graphical and easy-to-understand format. It allows for easy monitoring of the process and allows personnel to take appropriate action when required.

Real-Time Data Acquisition:

The AHT3801 also allows for real-time data acquisition for log purposes. This feature involves the logging of data at a regular time interval and can be used for trending and analysis of the process performance.

User Interface:

The AHT3801 provides a user-friendly graphical interface that enables operators to interact with the system easily and efficiently. It also allows for easy configuration and modification of settings if necessary.

Working Principle

The AHT3801 Panel Meter is powered by a 12 VDC supply. It works using pulse-width modulation (PWM) control, which is a technology used to control electrical current.The working principle of the AHT3801 is based on a voltage regulation system. When the applied voltage drops below the set point, the AHT3801 will begin to increase the voltage to bring it back up to the set point. This system of voltage regulation ensures that the desired output voltage is maintained even when the input voltage is fluctuating.The PWM technology used by the AHT3801 works by modulating the duty cycle of the PWM output. This means that the output voltage is determined by the pulse-width of each pulse in the PWM waveform. The pulse-width is determined by the setting of the AHT3801, which can be adjusted to adjust the output voltage to the desired value. The frequency of the PWM output is fixed at 100 kHz.The AHT3801 also provides a number of features which make it a useful tool for industrial applications. These features include adjustable alarm points, tachometer sensing input, and four-digit electronic display.

Conclusion

AHT3801 is a general-purpose electronic panel meter which is used in industrial applications for adjustment and monitoring of process parameters. It is based on a PWM technology which provides accurate voltage regulation and adjustable alarm points. It also provides a user-friendly graphical interface that makes the process of monitoring and controlling process parameters easier for operators.Overall, the AHT3801 is an ideal instrument for industrial applications, particularly for processes that require an accurate and reliable measurement and monitoring of parameters.
