The engine test stands used with advanced data-acquisition systems require a different type of pressure sensor than those used in the past.
Engine hydraulics and pneumatics operate faster and often, with higher pressures and temperatures. Accordingly, the pressure sensors have to be more reliable and rugged in order to reduce downtime.
In choosing the correct pressure sensor for your application, you must consider several specifications. You must decide which type of pressure sensor will give you the best results in your application.
