There are many different applications for low pressure sensors. As the name implies, they are used to measure changes in a low pressure environment with each specific model and type of sensor being rated for specific pressure levels.
These types of sensors can be found in different systems. In a vehicle, they can be found in the oil, coolant and even in the fuel systems. They are also used in many of the high-tech types of tires and are able to provide readings to the computer in the vehicle to signal when there is lower than ideal tire pressure.
Differences to Consider
With the different varieties and options in low pressure sensors, it will be essential to consider the use environment and the pressure range. Each company manufacturing these low pressure devices will have different kPa gauge ranges or other similar standards for their various stock items. It will be important to carefully select the correct gauge for the specific pressure ranges for the most accuracy and precision in measurements.
It will also be essential to check the sensor for the specific working conditions and exposure to different aspects of the system or the environment. This can include issues with high or low temperatures, the presence of specific types of chemicals or compounds or even the presence of EMI (electromagnetic interference).
There will also be a need to consider the right match in low pressure sensors if vibration or thermal shock may be an issue to consider. These are often not seen as considerations when making a selection in a sensor. However, if they aren’t considered, they can result in failures and very short lifecycles of the sensors.
Also, consider the mounting location, the configuration of the sensor and the ability to be certified or warranted for use in specific types of applications.
