At present, Inductive sensor is an essential component used in machines. What is an Inductive Sensor? 1. An inductive sensor is a device that uses the principle of electromagnetic induction to detect or measure objects. It has two versions and comprises of 4 main components: It uses coil or inductor for its construction. A pressure transducer is a device that measures the pressure of a fluid, indicating the force the fluid is exerting on surfaces in contact with it. Electrical pressure sensors . Inductive proximity sensors are contactless sensors used to only detect metal objects. Inductive sensors are nowadays indispensable for industrial applications. Piezo is a Greek term signifying “press” or “squeeze”.Piezoelectricity (also called the piezoelectric effect) is the presence of an electrical potential across the sides of a crystal when mechanical stress is applied by squeezing it. It mentions Inductive sensor advantages and Inductive sensor disadvantages. ... For example resistive capacitive inductive transducers… The total supply current will be: A. A manometer is an example of a local gauge. A pressure sensor can also be designed to perform as a pressure switch, which generates a simple on/off signal that will change state when a preset threshold is reached. A. eddy voltage. 32) Which sensor can detect nearby objects? There are many types, each suited to specific applications and environments. at the pressure below its vapor pressure can be used to measure temperature down to 1 K. High temperature: For high-temperature measurement upto 500°C the standard hydrogen gas thermometer with platinum-iridium bulb can be used, and for … Which of the following represents drawback of the inductive transducer for displacement measurement?

Following is the list of multiple choice questions in this brand new series: MCQ in Industrial Electronics Principles and Applications . They produce an output signal in the form of some variation in resistance, capacitance or any other electrical parameter, which than has to be converted to an equivalent current or voltage signal. They are, therefore, perfectly suited for monitoring the position of your hydraulics, such as when controlling the end position of hydraulic cylinders or monitoring valve positions. Fig. It is used for position and speed sensing. 10.5.2 Velocity Transducers 10.5.3 Force or Pressure Transducers 10.5.4 Temperature Transducers 10.6 Summary 10.7 Key Words 10.8 Answers to SAQs 10.1 INTRODUCTION Sensors can be broadly classified in two categories: discrete event and continuous. ASWDC (App, Software & Website Development Center) Darshan Institute of Engineering & Technology (DIET) How it Works. (a) Humidity sensor (b) Proximity sensor (c) Touch sensor (d) Pressure sensor ANS-b 34) Which proximity sensor detects metal objects? "Genuine" inductive pressure sensors operate in accordance with the principle of inductive position measurement whereby the core of the coil is connected to a diaphragm whose deflection it measures (Figure I 6). These short objective type questions with answers are very important for Board exams as well as competitive exams. Discrete event, or on/off sensor, changes its state based on the occurrence of some The rated electrical power required for operating inductive sensor 23 is 18 to 30 volts dc with a 150 milliamp maximum current. They are as follows: i) Variable permeability inductive transducer ii) Variable reluctance inductive transducer iii) Eddy current inductive transducer iv) Linear variable differential transducer. TI Precision Labs (TIPL) is the most comprehensive online classroom for analog signal chain engineers. 1(a), the proposed magnetic sensing unit mainly consists of a planar coil and two magnetic films (CoFeB film is employed in this study). Inductive sensors.
