Features of high precision pressure sensor "MS5525DSO"

MS5525DSO is a pressure sensor provided by TE Connectivity.
It can be measured from 1 to 30psi, and the measurement data is mainly 24bit, so it is possible to measure with high accuracy.

Equipped with SPI and I2C bus interfaces, it can be easily connected to existing microcomputers.

In this article, we will explain the following three major features of the MS5525DSO.

  1. Ideal for industrial applications due to its wide measurement range and high accuracy
  2. Board-mounted package for easy implementation
  3. Easy connection to existing microcomputers, realizing commercialization in a short period of time

 

1. Suitable for industrial applications due to its wide measurement range and high accuracy

The MS5525DSO can measure gage pressure, compound pressure and differential pressure from 1 to 30 psi.

Equipped with a delta-sigma analog-to-digital converter, it can measure highly accurate 24-bit digital pressure and temperature values. Since the calibration is performed at the time of shipment from the factory, the number of man-hours at the time of product shipment can be reduced.

This makes them ideal for industrial applications such as pneumatic controls, valve control systems, and leak detection.

2. The package is a board mount type, so it is easy to implement

The MS5525DSO package is a board mount type. Therefore, it can be easily mounted on a printed circuit board.

3. Easy connection to existing microcomputers and quick commercialization

The MS5525DSO has SPI and I2C bus interfaces. Therefore, it can be easily interfaced with a general microcomputer.

The communication protocol is simple and no complicated programming is required. Therefore, it can be incorporated into the product in a short period of time.
