An inductive pressure transducer uses the principle of inductance to convert the flexing of a diaphragm into the linear movement of a ferromagnetic core. In addition, they are insensitive to vibration, dust and moisture. An inductor develops a magnetic field when a current flows through it; alternatively, a current will flow through a circuit containing an inductor when the magnetic field through it changes. In this case LVDT is a secondary transducer. For example, a photocell (LDR) is a passive transducer which will vary the resistance of … Transducers which require an external power source for their operation is called as a passive transducer. It uses coil or inductor for its construction. Pressure transducers are used in many control and monitoring applications such as flow, air speed, level, pump systems or altitude. "Genuine" inductive pressure sensors operate in accordance with the principle of inductive position measurement whereby the core of the coil is connected to a diaphragm whose deflection it measures (Figure I 6). A pressure sensor can also be designed to perform as a pressure switch, which generates a simple on/off signal that will change state when a preset threshold is reached. ...
