2LP128 Application Field and Working Principle

2LP128 is a type of digital pressure switch. It is a fast microcontroller-based pressure switch having the features of adjustable pressure settings and USB connectivity. This type of switch is the widely used one, for it offers better precision and accuracy in comparison to many other available pressure switches.

Applications of 2LP128

The primary application of the 2LP128 is for use in oil and gas pipelines. This switch is an essential part of such systems since it helps in monitoring the pressure and the flow of the liquid, such as oil and gas, within the pipelines. It is an ideal choice for this type of application since it offers a high level of accuracy and precision. Additionally, it also provides the flexibility of being adjusted to specific pressure settings.

Apart from use in oil and gas pipelines, the 2 LP128 is also used in a variety of other applications. In the medical sector, this switch is used in devices like MRI scanners, X-ray machines, and other such medical diagnostic equipment. Likewise, it is also often seen in industrial processes such as in steam systems, cooling systems, and hydraulic circuits. It is even utilized in commercial applications, particularly to monitor heating, ventilation, and air conditioning systems (HVAC).

Working of 2LP128

The working principle of the 2LP128 is based on the microcontroller-based pressure sensing technology. The sensor features a piezoelectric transducer, which converts the mechanical energy of the system into electrical signals. This signal, in turn, is measured by the microcontroller within the switch. Once the received signal reaches a predetermined threshold level, the switch initiates an action.

The switch uses two pressure thresholds, one high and one low, to monitor the pressure of the system. The upper pressure threshold is the one set before the microcontroller initiates the action. Similarly, the lower pressure threshold is the one set by the microcontroller below which no action will be initiated. Thus, the pressure of the system is monitored in between these two pressure thresholds.

Moreover, the microcontroller in the 2LP128 digitally samples the pressure at a certain rate and interprets the actual pressure values. These pressure values are then compared to the predetermined thresholds set within the microcontroller. This comparison helps the microcontroller determine if the pressure is in the range of the set thresholds or not. If the pressure exceeds the upper threshold, the switch will then initiate the action.

The action initiated by the switch could be anything ranging from switching a safety valve to operating a compressor. This depends on the function of the switch and is defined by the user. For example, if this switch is used in an oil and gas pipeline, then the action initiated could be to switch off the pipeline valve in case the pressure exceeds the upper threshold.

Conclusion

The 2LP128 is a digital pressure switch which is primarily used in oil and gas pipelines. This type of switch offers better precision and accuracy in comparison to many other available pressure switches. In addition to this, it also offers the flexibility of being adjusted to specific pressure settings. The working of the switch is based on microcontroller-based pressure sensing technology, where the microcontroller compares the received pressure signals to predetermined thresholds set within the switch. The action initiated by the switch depends on the given application and is defined by the user.
