TYPES OF PRESSURE TRANSDUCER
What are the different types of pressure transducer?
Chemical Vapour Deposition
The Chemical Vapour Deposition method involves bonding a polysilicon layer to a stainless steel diaphragm. This is done at the molecular level to produce a sensor which then has a superior long term drift performance. Semiconductor manufacturing processess are used to create a polysilicon strain gauge bridge with superior performance at a very cost-effective price. Chemical Vapour Deposition units are the most popular sensor for OEM applications construction as they can offer excellent price and performance.

The Capacitance Type is used for a large variety of high volume OEM bespoke applications. Measuring capacitance change between two surfaces allows for transducers to detect very low pressure and vacuum levels. Their extremely robust construction lets capacitance units to be used in a huge range of applications. They offer great price and performance benefits.

Sputtered Thin Film
Sputtered film deposition creates transducers with maximum combined linearity, hysteresis and repeatability. These types of units allow for extremely high full scale accuracy and very low long term drift. Accuracy is as high as 0.08% full scale with long term drift as low as 0.06% full scale per year. They are most commonly used in critical applications where precision is a must-have.

Micromachined Silicon (MMS)
MMS transducers use micromachined silicon (MMS) diaphragms to sense pressure changes. The silicon diaphragm is protected from the process media by an oil-filled 316SS isolation diaphragm. MMS transducers are manufactured through common semiconductor techniques. These units off a great proof pressure, linearity and stability.
