In Electrical Transducer Nomenclature and Terminology standard, a sensor is defined as “a device which provides a usable output in response to a specified measurand” . The secondary transducer converts the output of primary transducer into electrical signal. Zero drift is defined as the change in output (∆y) without any corresponding change in input. The smallest change in a measured value that the instrument can detect is called the resolution of the instrument. Passive transducers are defined as those transducers that require external or auxiliary power supply for their operation of conversion of physical quantity into electrical signal. Signal filtering, amplification and analog to digital conversion are the most common input conditioning operations. Successive readings may be close to each other, but far from the true value. For example, a piezo-electric crystal transducer, being an active transducer, converts pressure into e.m.f.

Sensor/transducers specifications. They are the resistive type of transducers and the output voltage is proportional to the displacement and is given by: e o = ( x i /x i. Sensors generate a proportional electrical signal (voltage, current etc) to the measured output. A thermocouple is a transducer that converts temperature to a small voltage; the amplifier increases the magnitude of the voltage; the ADC (Analog to Digital Converter) is a device that changes the analog signal to a coded digital signal and the LEDs (Light Emitting Diodes) display the value of the temperature. Sensors need frequent calibration for many reasons. For example, for a temperature measuring instrument the input range may be 100-500 °C and the output range may be 4-20 mA. Cost: Cost of the sensor should be low. Sensors are the feedback elements which help sense the state of the controlled output. They are externally powered transducers, for example, a potentiometer. CHAPTER 1 MECHATRONICS, SENSORS AND TRANSDUCERS Introduction to Mechatronics systems Mechatronics is integration of mechanical engineering with electronics engineering and computer control in design and manufacturing of products and processes. Accuracy indicates the closeness of the measured value with the actual/true value and is usually expressed in percentage of full scale reading. Precision is the degree to which an instrument will repeat the same measurement over a period of time. Even though real sensors and transducers can behave quite differently in practice, when developing a mechatronic system we should use the ideal behavior as a reference for the design speci cations.
