NTC Thermistor Performance and Linearization of its Temperature-Resistance Characteristics Using Electronic Circuit
Get PDFThis paper critically discusses the performance of an NTC thermistor sensor in the temperature range 20 oC to 85 oC and provides a technique for linearization of the temperature sensed by the thermistor. The linearization was achieved by utilizing Wheatstone bridge electronic circuitry which responds to the thermistor and produces an output which is an exponential function of the temperature sensed by the thermistor sensor. A further simple and low-cost electronic circuitry responds to such output and converts the resistance measurement to provide a signal which represents the temperature. Moreover, the Wheatstone bridge signal conditioning circuitry was designed to have 0 – 100 mV output voltage within the considered temperature range. The physical characteristics of the thermistor (constant A and b ) were found to be 4.0015 x 10-5 ± 0.2956 x 10-5 Ω and 3514.8 ± 11.6 K respectively. The result also shows that the percentage nonlinearity was as low as 1.7 and a sensitivity value of 1.5661 mV/K was found for the thermistor, but the resolution of this thermistor sensor is 2 oC. However, the percentage of nonlinearity obtained was in agreement with the theoretical percentage nonlinearity

Design and Fabrication of Pneumatic Can Crushing Machine
Get PDFThis paper is based on the design and fabricate of a pneumatic can crusher that will reduce to the smallest possible amount of the volume of aluminum cans by 70%. The can crusher is made up of various parts containing parts such as a lever, base frame, can bin, piston cylinder arrangement, chain sprocket mechanism and bearing. The inspiration behind this design came from the wastages in eateries, canteens of big companies where people gather and consume a lot of canned beverages. Thus, it makes sense that there should be an easy way to dispose of used cans properly during large social gatherings. The Can Crushing machine works with the help of pneumatic single acting cylinder. The machine is portable in size, and as such is easily transportable. Most companies find it difficult to dispose of their used cans in hotels and canteens and to create enough storage space that is required. This paper deals with the operations, the design and structural analysis of can crusher. A Can crusher is a device to reduce large material object into a smaller volume. The crusher reduces the size or change the form of waste materials so that they can be disposed off or recycled easily. The Can crushing machine is designed to crush aluminum waste cans by 80%. reduction in volume. It is used primarily to ease transportation of aluminum waste for recycling purposes. The machine is designed to smash an empty can of diameter 65mm and height 120mm to height of between 25mm to 30mm. It uses compressed air for its operations with the following component parts: pneumatic cylinder, solenoid valve, control unit and hoses. The cans are fed into the hopper and the cans travel in an orderly manner through the chute into the crushing chamber. The air compressor through the pneumatic cylinder supplies the required crushing force. The crushed cans drop through the created space into the collection tray below the crushing chamber
