1. INTRODUCTION LabVIEW stands as a widely embraced software platform within the realm of the process industry. Its popularity stems from its capacity to deliver an intuitive graphical interface, adept data acquisition and analysis tools, as well as a versatile programming environment [1]. With LabVIEW, the development of real-time monitoring and control systems becomes feasible across an array of processes, spanning chemical manufacturing, power generation, and water treatment [2]. This software platform exhibits the ability to seamlessly interface with diverse instruments and sensors, thereby enabling the collection and analysis of process data. Moreover, LabVIEW empowers the provisioning of control signals to regulate process variables [3]. Through its adaptable nature, LabVIEW facilitates the real-time capture and scrutiny of process data from an assortment of origins, encompassing sensors, controllers, and other instruments. This platform can be tailored to effectuate real-time data analysis, presenting engineers and operators with graphical and statistical tools essential for informed decision-making [4]. LabVIEW also emerges as a potent tool for the development of remote monitoring and control systems. This capability empowers engineers and operators to oversee and regulate processes remotely.

The impetus driving this research arises from the demand for precise methodologies to fashion low-cost instruments catering to signal analysis, encompassing parameters like temperature, pressure, level, displacement, and strain. The aim is to enhance the performance of a multitude of instruments across aspects such as acquisition, linearity, sensitivity, accuracy, and resolution. Employing the system engineering prowess inherent in the Laboratory Virtual Instrument Engineering Workbench, improvements are sought in signal conditioning circuits, bolstered by remote indication technology powered by LabVIEW.
LabVIEW-based instruments present an economical, reliable, and versatile solution for capturing and analyzing an array of process signals, encompassing temperature, level, pressure, and displacement. Among these, pressure holds paramount importance as a pivotal process parameter warranting meticulous measurement and regulation across diverse sectors. Manufacturing applications specifically necessitate robust, high-performing, and interoperable software solutions. In this context, the integration of a proportional controller emerges as a noteworthy avenue, promising heightened precision and accuracy in process variable control, surpassing the efficacy of manual oversight. This augmentation bears the potential to yield enhanced product quality, heightened operational efficiency, and curtailed wastage.
2.1 Proportional Controller A proportional controller represents a category of control systems wielded within industries to govern a process variable, be it temperature, pressure, flow rate, or others, aligned with a designated set point [5]. The controller's functionality hinges on imparting a control signal that maintains proportionality with the disparity between the established set point and the actual measured process variable. The block diagram in Figure 1 delineates the schematic visualization of a proportional controller.
