Pressure Sensor Comparison Report: Electrical Engineering Analysis

This report provides a comparative analysis of pressure sensors from three different manufacturers: REV ROBOTIC, KM41/45, and HONEYWELL FP5000. The analysis includes detailed specifications such as accuracy, response time, supply voltage, working pressure range, and temperature limits. The report highlights the applications of these sensors, particularly in industrial settings like refrigeration, HVAC systems, and hydraulic pressure systems. A comparison chart is included to summarize the various sensor properties. The report also references relevant research papers on pressure sensors and their applications. This document is available on Desklib, a platform providing students with access to past papers and solved assignments for academic support.

The technologically advanced sensors of today tend to be more accurate, reliable as well as
rugged in comparison to before. These features render them ideal for use in long term
environments and even withstand harsh conditions of the most extreme conditions of vibration,
humidity or even temperature. Industrial pressure sensors find their uses in quite wide
applications ranging from refrigeration, HHAC compressors as well as variable speed pumps all
the way to hydraulic pressure, water or even oil (Tamez-Duque et al., 2015). The specifications
