Therefore, design and development of sensing and recognition for different anions have grown into an area of great interest in recent years [,,,,,,, ].Among various anions, fluoride plays significant roles in chemical, environmental and biochemical process.
2016-5-1 The peak temperature is the maximum measured bridge voltage which is then converted into temperature. With each grinding run the temperature increases because the grinding wheel comes closer to the sensors and to the thermocouple. The measured temperature of the thermocouple is lower than the measured temperature of the thin film sensors.
2018-1-1 Lezanski [7] proposed an intelligent system for condition monitoring of the grinding wheel using AE sensor, vibration meter, and piezoelectric transducer. ANN and neuro-fuzzy models were developed to classify the condition of the grinding wheel. It was concluded that for the development of a fuzzy logic system with many input variables, the
The acoustic sensors placed on the grinding machines must, therefore, become the machine and operator's sixth sense. That is mostly needed as the current automation of the machining processes no longer allows a direct view of the part, due to the high operating pressures of the lubricants and coolants required to work at high speed.
2019-2-1 For this purpose, two acceleration sensors mounted on the workpiece spindle and the tailstock, an acoustic emission (AE) sensor applied to the grinding wheel, and the motor current of the directly driven headstock spindle are considered.
2008-2-1 On-line particle size soft-sensors play an important role in the efficient operation of control systems in many industrial grinding plants. To cope with disturbances and changing operating points it will be necessary to adapt the soft-sensor parameters to the new conditions.

2014-6-18 Unfortunately grinding wheel performance is difficult to predict, and workpiece damage is commonly prevented by frequent dressing of the wheel surface. However, such over dressing is also costly in unnecessary machine down time and consumption of the grinding wheel.
The sensor is mounted above the grinder (see Figure 1) and monitors the radial position of the rotary drive shaft. A bipolar analog output indicates the position of the grinding wheel relative to the ground part. The signal from the sensor directly controls the position of the grinder
