Question 3 4) The diagram illustrates a pressure measuring system. mV mA meter converter pressure input The system consists of pressure transducer connected to a converter. The output mV is related to the input pressure by V = 30p where p. is in bar and V is in mV. The converter output in mA is related to the input by I= 4 + 0.2V. The current is sent to a meter. What is the pressure when the meter indicates 15mA? b) With the aid of sketches write briefly on the following Spring balance Boudon gauge c) A hydraulic load cell is required to measure a maximum load of 500KN. If the effective diameter of the diaphragm is 200mm, calculate the maximum pressure to be indicated on the Bourdon gauge. Assuming the scale is linear and operates over an A. C. of 270 volts. Calculate the sensitivity of the pressure guage. i. ii.
