How Does a Strain Gauge-Based Pressure Transducer Work?
Pressure transducers work similarly to force transducers. In this article, get an overview of the working principle of strain gauge-based pressure transducers.
There is a variety of different technologies used within pressure sensors to provide accurate results. The following section will highlight some of these.
Other pressure sensors that also do not use a measuring body can be thermal or ionization sensors, which use changes in thermal conductivity due to density changes in the flow of charged particles to measure the applied pressure.
There are a variety of properties that can be used to classify pressure sensors, including the pressure range they measure, the temperature ranges of operation, or the type of pressure they measure. Different pressure types can be absolute, gauge, sealed gauge, and differential pressure.
The obvious advantage of an absolute pressure sensor is to always measure against the same reference pressure (vacuum) and therefore be unaffected toby atmospheric pressure changes and less affected by temperature changes.
HBK has over 65 years of experience in developing and manufacturing test and measurement equipment, including strain gauge-based pressure sensors. If you are looking for more information on our range of pressure sensors, please contact us.

HBK pressure transducers and pressure sensors ensure precise results up to accuracy class 0.01. Thanks to strain gauge technology and monolithic design, the sensors are extremely durable and are also suitable for high-pressure measurements up to 15,000 bar.
