Dept. Q7. The bourdon tube senses the pressure and converts it into a displacement. It can measure physical quantities like displacement, temperature, motion, level, pressure, etc. In general, the measurand could be a linear or rotary displacement, pressure, force, torque, vibration velocity, and acceleration. to understand the working principle, consider a conductor rod. Q8. This paper presents an inductive pressure sensor which can be employed for the acquisition of biomedical signal, and these signals can be extremely vital in monitoring and diagnosing human body conditions. Sensing Element The physical quantity or its rate of change is sensed and responded to by this part of the transistor. Some of the more important ones are discussed in terms of the transducer itself as well as the overall measuring system. The transducer used for the measurements is/are A. Thus, pressure may be monitored within the inner walls of a well housing without requiring holes to be drilled which would threaten the hydraulic integrity of the wellhead. The most commonly used type of transducer is variable resistance transducer. Strain gauges are mounted on a bending beam. These physical quantities are noted as measurands. Piezoelectric transducer. Pressure is a force per unit area. The differential measuring principle of our LVDTs ensures minimum temperature effects on the results of the measurements. A self-inductance or mutual inductance is varied to measure required physical quantities like displacement (rotary or linear), force, pressure, velocity, torque, acceleration, etc. An inductive transducer based pressure sensor for biomedical applications Abstract: This paper presents an inductive pressure sensor which can be employed for the acquisition of biomedical signal, and these signals can be extremely vital in monitoring and diagnosing human body conditions. Inductive sensor mainly includes an induction loop which is enough for detecting electromagnetic. An important application of inductive transducer based pressure sensor is fabrication of such sensor on a chip which is fitted to a pacemaker [11]. When you’re troubleshooting pressure transducer problems, the first step is to ascertain that the device in place is the right one for its environment. When specifying a pressure transducer for a process measurement, a number of items have to be considered. In a reluctive transducer, displacements occur in the magnetic coupling between a pair of coils. The same method can be extended to develop a null-balance type instrument as shown in the figure below. An inductive sensor is a device that uses the principle of electromagnetic induction to detect or measure objects. An electrical transducer is a device which is capable of converting physical quanties into a proportional electrical quantity such as voltage or electric current.Hence it converts any quantity to be measured into a usable electrical signal. The electronics integra-ted in the device supply the primary coil, evaluate the vol- tage induced in the secondary coils and provide a defi ned output signal or convert this into a bus signal. ANSWER: D. All of these . To protect the pressure transducer against these high temperatures, you will need to apply a siphon effect, where the transducer is moved away from the process and the fluid (liquid or gas) first runs through a section of metal pipe to dissipate the heat of the media being measured.
