PV70W14-18PX

The PV70W14-18PX is a type of differential pressure sensors applicable in multiple fields, including but not limited to, the water management industry. In this article, the application field and working principle of the PV70W14-18PX is explored in detail.

Application Fields

The PV70W14-18PX differential pressure sensors are primarily designed for the water management industry. It is used for measuring the pressure difference between two points in a pipe. This type of pressure sensor is ideal for use in pipes where water is flowing and pressure needs to be monitored. This can be used in a variety of applications, including, but not limited to, monitoring pressure in irrigation systems, monitoring water pressure in residential water systems, preventing overpressurization in water systems, and monitoring pressure in commercial water systems.

The PV70W14-18PX is also suitable for use in other industries, such as commercial buildings, for the purpose of monitoring air pressure and providing ventilation. In industrial processes, this type of pressure sensor can be used for applications such as monitoring the pressure within tanks or process chambers, and controlling processes which require precise control of pressure levels. Additionally, the sensor can be used in laboratory settings for measuring pressure in gas and liquid systems.

Working Principle

The working principle of the PV70W14-18PX differential pressure sensor is based on the use of a piezoresistive metallization system. This system involves the use of two foil strain gages that are located on opposite sides of a silicon chip. When a pressure difference occurs between the two points, the foil strain gages will expand or contract at different rates due to the differences in pressure. The strain gages will then convert the mechanical deformation into electrical signals that can be read by a computer. The signals can then be used to measure and calculate the difference in pressure between the two points.

The PV70W14-18PX is able to measure pressure differences up to 40 mbar, and has an accuracy of ± 0.5 mbar. The sensor also has a fast response time of 0.4 ms and can operate over a wide temperature range of -20°C to +70°C. Additionally, the sensor has a wide power supply range of 10 to 30 volts DC and can be used for both AC and DC signal input.

In summary, the PV70W14-18PX differential pressure sensor is a highly accurate and reliable sensor suitable for a variety of applications. It is particularly useful for use in the water management industry, where pressure levels need to be monitored in order to ensure a safe and efficient system.
