It becomes transducers when connected in a bridge circuit. Sensor : Sensor is the device that detect the change in the environment. 1. 10 µV/°C in case of a voltmeter affected by ambient temperature change. The controller generates a control signal to achieve a desire level of output. Successive readings may be close to each other, but far from the true value. 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. Following are static characteristics of a measurement system. Sensitivity is defined as the rate of change of output to the change in input. This tutorial is mainly descriptive.

Definition – Mechatronics is synergetic integrartion of mechanical, electronics, controls and information technologies to obtain the best solution to a given technological problem. A precision instrument indicates that the successive reading would be very close or in other words, the standard deviation of the set of measurements would be very small. • Note : sensor/transducer are one andthe samesensor/transducer are one and the same. Note that a transducer and a sensor are not the same. Advanced material Technology (7.5.2) Uploaded by. Notes for Sensors And Transducers - ST by Anita Mohanty. Measurement is an important subsystem in any major system, whether it may be a mechanical system or an electronic system. 3. University. When a transducer converts a measurable quantity (sound pressure level, optical intensity, magnetic field, etc) to an electrical voltage or an electrical current we call it a sensor. Unit 4. It provide output response to specific input measured which may be physical quantity. Precision is the degree to which an instrument will repeat the same measurement over a period of time. It is useful to anyone studying measurement systems and instrumentation but it is provided mainly in support of the EC module D227 – Control System Engineering. In this type of classification, the transducers are classified on the basis of principle of transduction, viz. It can be temperature sensor, pressure sensor or Humidity sensor.

Typical Senso… sensor differs from a transducer in the way that a transducer converts one form of energy into other form whereas a sensor converts the received signal into electrical .form only A sensor's sensitivity indicates how much the sensor's output changes when the measured quantity changes. ( Log Out /  PRINCIPLES OF SENSORS & TRANSDUCERS • Linearity • The relationship between output and input is a key parameter for sensors and transducers. These are a number of performance related parameters of a transducer or measurement system. In a process industry 4 basic and very important parameters to be measured and controlled are: 1) Flow 2) Temperature 3) Pressure 4) Level 3. The smallest change in a measured value that the instrument can detect is called the resolution of the instrument. Example of Transducer: Strain gauge, and Piezoelectric Transducer.
