A pressure transducer, also known as a pressure sensor, is a device that converts pressure into an electrical signal. At its most basic, the transducer measures force applied by a fluid (such as a gas or liquid) and then transmits data or uses the resulting information to regulate the pressure.
Typically, a pressure transducer consists of two main parts: a pressure sensitive element (transducer) and a signal conditioning electronics. The pressure sensitive element can be made from different materials and based on different technologies like piezo-resistive, capacitive, electromagnetic, etc. One common type is the piezo-resistive strain gauge.
When pressure is exerted on this element, it results in a physical change within the sensor. This change could be a deformation or strain, which is then converted into an electrical signal by the transducer.
The signal conditioning electronics then interpret this signal and convert it into a readable output, often in the form of a current or voltage. The readings can then be displayed, recorded, or used to control other devices.
Pressure transducers are widely used in various fields like aerospace, automotive, HVAC systems, medical devices, and industrial controls for monitoring and controlling systems. They play a critical role in maintaining safety, efficiency, and performance standards across a range of applications.
Our range of pressure transducers is based on the Titan Series using either a ceramic piezo-resistive or stainless-steel oil filled piezo-resistive silicon sensor.
