A Sensor is a device that measures a physical quantity and translates it to a signal. The quantity is usually Pressure, temperature, displacement, etc. The pressure sensor is an instrument consisting of a pressure-sensitive element to determine the actual pressure applied to the sensor and convert its output signal. More easily, the Pressure sensor senses the pressure then converts the pressure to a small electrical signal that is transmitted and displayed. Pressure sensors can also call as to be called pressure transducers, pressure transmitters, pressure senders, pressure indicators, piezometers, and manometers. When pressure sensing technologies were first manufactured they were mechanical and used Bourdon tube gauges to move a needle and give a visual indication of pressure. Nowadays we measure pressure electronically using a pressure sensor.
Benefits of the pressure sensor
- It has low cost and high durability.
- It has Good resistance to shock, vibration, and dynamic pressure changes.
- Circuits are very simple.
- It also allows high-resolution measurement.
- It also has Linear output and millisecond response time
The drawback of a pressure sensor
- A pressure sensor is unsuitable for battery-operated systems as well as low power.
- It also has a Limitation on scaling down as it can increase the power consumption with diminished sensitivity.
Application of pressure sensor
- Pressure sensors are used throughout many industries for applications including Food processing industries that use high-pressure pasteurization systems to destroy many pathogens and produce safe and healthy food. Besides it also uses pharmaceutical industries to monitor and maintain pressure inside drug manufacturing chambers to protect them from germs. Pressure sensor also uses in monitoring gas pressure in the petroleum industry and tire pressure in vehicles.
