The number of waves or signals that occur in a fixed time interval specifies the frequency and it is measured in the units of Hertz (Hz). Based on the values of frequency, the frequency range is varied and it is determined. When the sound produced is at a higher level than the human hearing range, then it is said to be ultrasound, with a frequency spectrum of over 20KHz. The device that can generate or sense the ultrasound is called an ultrasonic transducer and ultrasonic sensor. The various … [Read more...]

A capacitive transducer is one kind of device, used to change the energy from one form to another. Generally, transducers are frequently used at the boundaries of control systems, measurement, & automation, wherever electrical signals are changed from different physical quantities like force, energy, light, torque, position, motion, etc. There are two kinds of transducers like electrical and mechanical. Electrical transducers convert the physical quantities to electrical whereas … [Read more...]

In fluid power circuits, pressure is an essential factor. A pressure transducer is used to change the pressure of a fluid into an electrical signal to check & control the pressure within electronic control systems. Once these transducers are connected to a suitable electrical source then it will generate an electrical output signal like current frequency or voltage which is proportional to the force. There are different kinds of transducers are available which are used to generate linear … [Read more...]

Any type of electronic system requires communication with the real world. To make it done sensors and actuators are used. The purpose of the sensor is to sense the different forms of energy either it can be of movement, thermal, electrical, or magnetic. Where the actuators are used to switch currents or voltages. Sensors including actuators are termed as Transducers. The main purpose of this device is to convert the applied form of the signal into other signals based on the requirement of the … [Read more...]

A device that can convert one form of energy into another form is called a transducer. That means a transducer has the ability to convert a signal of one form to another form. These are mainly used for automation, measurement, and control systems because the electrical signal needs to be converted to physical quantities like force, torque, motion, etc. An electric motor, solar cell, incandescent bulb, microphone, etc are examples of transducers. A transducer can be electrical or mechanical. An … [Read more...]

Resistive transducers are very important devices from an industrial point of view. They are used in calculating physical quantities like temperature and pressure which you would otherwise find really difficult to measure. Transducers can make industrial processes a lot simpler. A resistive transducer is basically a type of transducer whose resistance changes according to the change in environmental conditions. We are able to measure this change in resistance using various kinds of measuring … [Read more...]
