Most types of pressure sensors are built to work in a very wide range of environment and conditions. The same is true for any low pressure sensor, but they are designed differently from other types of sensors and this needs to be carefully considered when determining where and how the sensor will be used. Choosing the sensor that is specifically designed for a particular environment and system will be critical to a long life and reliable data.
The Difference
In order to be able to measure slight changes in low pressure systems, these sensors have to be designed with a very thin diaphragm. This allows even minute changes in pressure to cause the change in the diaphragm to then be converted into an electric signal and recorded. The flexibility of this very thin material is critical to the effectiveness and accuracy of the low pressure sensor.
This very thin diaphragm is, of course, protected by the outer casing of the sensor as well as the design itself. This outer protection is not enough to completely address all the possible conditions that may impact the functioning of the component.
Vibration
Ongoing vibration as could be found in an engine or in an industrial application can be very damaging to a low pressure sensor. This potential for damage will increase if the vibration is combined with shock or sudden impact to the sensor.
With a sudden impact or shock, the diaphragm can be damaged so that it no longer functions, resulting in immediate loss of the readings from the system. It is also possible that with vibration combined with shock the diaphragm simply deforms, which will result in lower accuracy of the sensor.
Temperature
Many of the models and designs of low pressure sensors are designed with specialized thermal compensation in the system. This will help to prevent any irregularities or inaccuracy in reading when the ambient temperature changes or it is operated at high or low temperatures.
It will be important to use the sensor only in the environmental conditions where it is recommended. This includes selecting the position of the sensor to avoid changes in cold or heat by other components in the system.
