Industrial Pressure Transducers

A pressure transducer - also known as a pressure transmitter - is a sensor which converts pressure into either an analogue or digital signal so that it can be processed by the user.

Industrial Pressure Transducers are suitable for use within harsh industrial environments and applications. They have certain characteristics which ensure they are not compromised within harsher, more demanding areas.  

Industrial Pressure Transducers have a rugged enclosure; they are often water resistant as well as being resistant to dirt and dust. They are robust, strong and offer high accuracy within harsh and demanding surroundings. They have a wide operating temperature range to ensure accuracy.

Considerations when selecting your Industrial Pressure Transducer 

When selecting an Industrial Pressure Transducer for your application it is important to account for the following;

Pressure range - pressure range is the most important factor; choosing an industrial pressure transducer with a range which is too wide would only use a small amount of the range meaning it would not be as accurate. Choosing a pressure transducer with a range which is too small may damage the sensor whilst in use. It is recommended to use a pressure sensor where the application pressure ranges use roughly 50-75% of the sensors over all pressure range. 

Accuracy - accuracy is another important factor when it comes to selecting a pressure transducer. The desired accuracy level varies depending on the application. If your application requires a high level of accuracy it is best to choose a pressure transducer with +/-0.1% accuracy.

Temperature - very often in industrial environments the temperatures can be very high, for this reason it is important to choose a pressure transducer with a wide operating temperature range. This will mean the accuracy of the pressure transducer will not be compromised in an industrial environment. 

Environment - as well as being dirt and dust resistant, industrial pressure transducers will often be resistant to shock and vibration. Depending on what environment they will be operating in, this will have to be considered. The amount of space available within the application also needs to be taken into consideration as this affects the size of sensor selected.
