Please solve a b c e and f
Explain the significance of the following information given in the specification of transducers: A piezoelectric accelerometer. Non-linearity: 0.5% of full range. A capacitive linear displacement transducer. Non-linearity and hysteresis: plusminus 0.01% of full range. A resistance strain gauge force measurement transducer. Temperature sensitivity: plusminus 1% of full range over normal environmental temperatures. A capacitance fluid pressure transducer. Accuracy: plusminus 1% of displayed reading. Thermocouple. Sensitivity: nickel chromium/nickel aluminum thermocouple: 0.03 mV/ degree C when the cold junction is at 0 degree C. Gyroscope for angular velocity measurement. Repeatability: plusminus 0.01% of full range. Inductive displacement transducer. Linearity: plusminus 1% of rated load. Load cell. Total error due to non-linearity, hysteresis and non-repeatability: 0.1%.Explanation / Answer
a)
Ans:
piezoelectric accelerometers convert one form of energy into another and provide an electrical signal in response to a quantity, property, or condition that is being measured. This conversion is done via the mass spring system
b)
Answer:
Capacitive displacement sensors are non-contact devices capable of high-resolution measurement of the position and/or change of position of any conductive target”. They are also able to measure the thickness or density of non-conductive materials. Capacitive displacement sensors are used in a wide variety of applications includingsemiconductor processing, assembly of precision equipment such as disk drives, precision thickness measurements, machine tool metrology and assembly line testing.
c)
Answer:
It is a device used to measure strain on an object. The most common type of strain gauge consists of an insulating flexible backing which supports a metallic foil pattern. The gauge is attached to the object by a suitable adhesive, such as cyanoacrylate. As the object is deformed, the foil is deformed, causing itselectrical resistance to change
e)
Answer:
A thermocouple is an electrical device consisting of two different conductors forming electrical junctions at differing temperatures. A thermocouple produces a temperature-dependent voltage as a result of the thermoelectric effect, and this voltage can be interpreted to measure temperature. Thermocouples are a widely used type of temperature sensor.
f)
Answer:
Applications of gyroscopes include inertial navigation systems where magnetic compasses would not work (as in the Hubble telescope) or would not be precise enough (as in intercontinental ballistic missiles), or for the stabilization of flying vehicles like radio-controlled helicopters or unmanned aerial vehicles, and recreational boats and commercial ships. Due to their precision, gyroscopes are also used in gyrotheodolites to maintain direction in tunnel mining.Gyroscopes can be used to construct gyrocompasses, which complement or replace magnetic compasses (in ships, aircraft and spacecraft, vehicles in general), to assist in stability (Hubble Space Telescope, bicycles, motorcycles, and ships) or be used as part of an inertial guidance system
