In this block diagram of a simple measuring system, there are three basic elements: A Sensor is a device that is used to detect changes in any physical quantity like Temperature, Speed, Flow, Level, Pressure, etc. The output mechanical quantity can be anything like displacement, force (or torque), pressure and strain. Oscilloscope Kits Beginners Input Transducers measure non-electrical quantities and convert them into electrical quantities. For example, a Microphone is a Sensor, which converts sound waves into electrical signals and a Loudspeaker is an Actuator, which converts electrical signals into audio signals. Active Electrical Transducers A basic instrumentation system consists of various devices. Raspberry Pi Starter Kits They produce an electrical signal proportional to the input (physical quantity). Hence stress is measured. TYPES OF TRANSDUCERS. Instrumentation is the art and science of measuring and controlling different variables such as flow, level, temperature, angle, displacement etc. Tachometers Basically, the two different types of Transducers are Mechanical Transducers and Electrical Transducers. In contrast, a Resistance Thermometer, also reacts to changes in temperature, but the response is a change in resistance of the element. With a range of mounting styles, it's important to learn which type of transducer in correct for your boat and boating needs. The performance characteristics of a Transducer are key in selecting the best suitable transducer for a particular design. • Passive Transducers - These need an external power source, for example Potentiometer, Strain Gauge, etc. a thermocouple) Pressure transducers (e.g. Resistive Moisture Transducers Following is small list of transducers classified based on the physical quantity and corresponding examples.
