There are many different applications that require the use of a Honeywell pressure sensor. Typically used to measure pressure changes in gasses or liquids, they generate an electronic signal that then turns a circuit on or off to create the desired action.

Honeywell has long been one of the most recognized producers of pressure sensors around the world. They can be found in everything from barometers to vehicles and airplanes. They are also used for flow sensing within systems as well as depth sensing in tanks or other types of storage facilities. Leak testing can also be completed through the use of in-line and system based pressure sensors.

The Types

Depending on the type and application of the various Honeywell pressure sensor models, different types of measurement options are available. Understanding what needs to be measured is critical in selecting the right type of pressure sensor for a specific application.

  • Vacuum pressure sensors – these are used to measure negative air pressure, or when the pressure is below that of the atmosphere. It can also be used to measure low pressures compared or relative to the pressure found in a vacuum.
  • Sealed – with these types of pressure sensors, the measurement is between a fixed pressure and the pressure to be regulated. This is important in many applications because weather conditions and other factors can change the atmospheric pressure, which in turn changes the consistency of the sensor. By having a fixed pressure to compare these variations are eliminated.
  • Absolute pressure sensor – this is measuring the pressure compared to an absolute or perfect vacuum.
  • Differential pressure sensor – this measures the pressure on the two sides of a connection. This is essential in monitoring pressure changes within the system to allow the flow of the liquid or gas between the two sides to create the desired readings on each side.
  • Gauge pressure sensor – the gauge pressure sensor is also designed like a differential pressure sensor, but with one side of the system measuring atmospheric pressure. One of the best examples of this is the tire gauge, as when the tire is at the same pressure as the atmosphere, it registers nothing on the gauge.

The various Honeywell pressure sensor units are designed to provide specific types of pressure measurements and will have specific PSI or pounds per square inch ratings. Choosing the right sensor will be a factor of the type of measurement required combined with the actual pressure through the system.
