Pressure transducers and pressure sensors often consist of a spring element on which multiple strain gauges are installed. Hence it converts any quantity to be measured into a usable electrical signal. The deflection of the internal diaphragm is measured and converted into an electrical output. The resistive transducer element works on the principle that the resistance of the element is directly proportional to the length of the conductor and inversely proportional to the area of the conductor. A high accuracy stable pressure transducer often recommended as calibration standard for gas pressure and density, is obtained by making a thin walled cylinder oscillate continuously in one of its vibration modes – specifically circumferential mode using limit cycle feedback system. In some cases, the problems of the transducer can be determined by repairing, recalibration otherwise this transducer may be changed. It uses a sensor capable of converting the pressure acting on it into electrical signals. The working principle of the melt pressure sensor is that the pressure of the medium directly acts on the diaphragm of the sensor. More complex pressure transducers include an electronic circuit for rationalising the transducer output signal so that there is very little difference from one transducer to another of the same type. Fixing the transducer on to the end of a long piece of pipe directly or via a manifold block requires a very simple mechanical connection such as a G1/4 (1/4 BSP) or 1/4 NPT male/female thread which are both very popular fittings used in most countries. What is the most likely cause of a pressure transducer failure? This allows the pressure to be monitored by microprocessors, programmable controllers and computers along with similar electronic instruments.
