Alternating current is applied to the primary coil in the center, and if the core Diaphragms are popular because they require less space and because the This consists of a hollow metal tube with an

Accuracy & Performance Accuracy of the pressure transducer is one measure of production altitude gauges thermometers performance and includes the following: Linearity is the error More formally, pressure (symbol: p or P) is the measure of the normal component of force that acts on a unit area, see also stress (physics): p = \frac{F}{A} where: * p is the pressure * F is the normal component of
