A requirement to sense glass bottles leaving an automatic washer on a production line conveyor belt...

A requirement to sense glass bottles leaving an automatic washer on a production line conveyor belt has been notified to you. The output from the sensor is to be of binary form, i.e. logical 1 when the part is present and logical 0 when no part is present. It is also necessary to ensure that a change of sensor state occurs closer to the sensor when a bottle approaches than when it moves away. The switching distance will lie between 5 and 20 mm. The production line is for food products and the environment is clean and maintained at a temperature of 15°C. Bottles will pass the sensor at the rate of 10 every second. There is no requirement for protection from contact with objects but it must be proof against water drips.

(a) Recommend a suitable sensor and justify your recommendation. Sketch a diagram that shows the functional blocks within the sensor and explain each function.

(b) Would the recommended sensor be suitable if a change was made from glass to plastic bottles?

An environmentally progressive small manufacturer in South Dakota has observed that her gas bill in February (the coldest month of the year) is usually about $900 (for space heating only). She uses a large natural gas space heater whose efficiency is known to be about 89%. She is considering upgrading to a furnace that uses a water source heat-pump with a coefficient of performance of 4.2. The heat-pump operates on 240 VAC electricity. Furthermore, she plans to install a wind turbine to generate enough electricity to power the new heat pump. The turbine will be connected to lead-acid batteries, each 12 VDC, but connected in strings of 5 batteries in series. In planning the wind turbine system, to choose an appropriate turbine and tower height, she needs to estimate the daily DC load that the wind turbine system would need to supply to the inverter on the ground. The inverter’s efficiency (in converting 60 VDC to 240 VAC) is 91%. Estimate the daily DC load (in Wh per day) as input to the inverter to power the heat-pump (for an average day in February). Put a box around this final estimate. By the way, her natural gas costs $6.25/mcf and the energy content of the gas is about 1030 btu/ft3. The electricity she is currently using costs $0.095/kWh.
