Difference Between Current Transducers And Sensors


The physical devices, current transducers and sensors are might used by some people interchangeably. These devices are used in numerous electrical and electronic appliances and gadgets. But, people fail to make a difference between current transducers and sensor. Because, Current Transducers are sometimes found in sensors. The main difference between current transducers and sensors is, the sensor is a physical device, that senses a physical quantity and then converts it into signals which can be read by an instrument or the user. The current transducer is also a physical device, that converts one form of energy into an another form. The best example of a current transducer is an antenna. Just Because of it converts electricity to electromagnetic waves. A sensor also converts one form of energy to another form, shows that it senses a physical quantity and converts it into an electrical signal.

Difference between Current Transducer and Sensor:
People get confused with both terms Current Transducers and Sensors, they do not understand why transducers are used in sensors devices. In a multi-operational device, a transducer converts one form of energy to another form and this converted energy is measured to the user for other measurements using sensors. This is mystifying to see contact transducers are being used in sensors for detecting energy levels and then converts them into electrical energy so as to be shown on a screen.

About 20 years ago, the application of the Current Transducers are used in tape heads of cassette players to transfer the magnetic information by direct contact with the magnetic tape. Then, this data was converted into form of electrical signals. These signals were sent to the load speakers and then converted to sound format to listen.

Coming to another type of Current Transducers like immersion and paintbrush transducers. Immersion transducers were used to measure energy in the form of pressure, sound so on. Paintbrush transducers operate in the air and these transducers are also very much similar to the immersion transducers.

The main reason or purpose to use a senor is to convert an energy into a one form which is noticeable by the user. To make this possible, a sensor may contain a transducer as they are capable of converting from one form to another. The simplest example of the current transducers is an LED (Light Emitting Diode) converts light energy into electrical energy. The best example of a sensor is the sensors used in bikes and cars which can detect the touch and activates the sirens. There are also cases when both the physical devices are the similar. For example, a bi-metallic spring is used to measure the changes in temperature and if a pointer is attached to the bi-metallic spring, and may well be the entire sensor.

Different types of Limit Switches

Rotary Geared Limit Switches The operating of the Limit Switch is to prevent the mechanism or drive at the intense forward/reverse positions. The Limit Switches are significantly suited to use on reversing drives like a hoist, winches, rolling mills and various other mechanisms used in steel plants such as coke ovens, feeding machinery, valve drives etc. The contacts of Limit Switches are forty amps rated ceaselessly at 500 Volts A. C. The Limit switch is often supplied with two NC contacts or four NC contacts or (2 NO + two NC) contacts as per the need. For Series Limit Switches are shields are provided. The frequency of switching of each contact is suitable for a maximum of 720 operations per hour. The speed of the driving shaft rotation shouldn't be over 60 rpm. Features:- High durable standards Optimum performance Easy to install Counter Weight Limit Switches A metal structure offers the required stability to Counter Weight Limit Switches that job on heavy c...

What is an Op-Amp? Operation, parameters & characteristics

What is an Op-Amp? Operational amplifiers are linear devices that have all the properties required for nearly ideal DC amplification and are therefore used extensively in signal conditioning, filtering or to perform mathematical operations such as add, subtract, integration and differentiation. An Operational Amplifier, or op-amp for short, is on a very basic level a voltage intensifying gadget intended to be utilized with outside criticism segments, for example, resistors and capacitors between its yield and information terminals. These input parts decide the subsequent capacity or "activity" of the enhancer and by ideals of the diverse criticism setups whether resistive, capacitive or both, the intensifier can play out a wide range of tasks, offering ascend to its name of "Operational Amplifier". Op-amp operation The amplifier’s differential inputs contains a non-inverting input with voltage (V+) and an inverting input with voltage (V−). Ideally, an op...

What is MOSFETs: Types & How to MOSFET as a switch

MOSFET stands for metal-oxide-semiconductor-field-effect transistor. It is a special kind of field-effect transistor (FET). The MOSFETs could be a voltage controlled device. The MOSFET has “gate“, “Drain” and “Source” terminals rather than a “base”, “collector”, and “emitter” terminals in a very bipolar transistor. By applying the voltage at the gate, it generates AN electrical field to control the current flow through the channel between drain and supply, and there's no current flow from the gate into the MOSFET. The power MOSFETs are special to handle the high level of powers. The power MOSFETs is widely used in the n-channel enhancement mode, p-channel enhancement mode, and in the nature of n-channel depletion mode. Here we've got explained regarding the N-channel power MOSFET. Basic Statures of Power MOSFET There is three main basic status in the power MOSFETs. ·          On sate resistance ·     ...
