information on inductive sensors into a single source. The intent is to help the reader understand where inductive sensors can be utilized, how to best apply them, and to understand their performance. Why Kaman? Kaman Precision Products has over 40 years of experience designing, testing, and manufacturing non contact inductive measuring systems. A four-terminal connection setup was employed and the excitation frequency was fixed at 100 kHz for capacitive measurements and at 25 kHz for inductive measurements. The sensor position was fixed and the sample was displaced to change lift-off. Lift-off could be adjusted from 0.1 to 4 mm with a resolution of 0.1 mm.
what is inductive sensor

The correction algorithm has successfully improved the thickness measurement precision from 0.19 mm to 0.07 mm. A higher accuracy of thickness measurement is also achieved, with the mean of the corrected thicknesses equals to the true thickness to ±0.01 mm. The algorithm also enabled the detection of a thickness loss of 0.09 mm.Inductive coupling Permanently installed sensor Structural health monitoring Ultrasound ABSTRACT An inductively coupled ultrasonic transducer system (ICTS) is a lightweight, wireless, battery-free, and low- profile (0.5 mm thick) permanently installed sensor system for measuring remaining wall thickness at fixedThis paper describes a pulsed eddy current (PEC) based non-destructive testing system used for experimental evaluation of material thickness and properties. Both classical and modern sensing methods of magnetic field have been carried out. An inductive as well as a giant magnetoresistive sensor based (GMR) probe have been used for sensing and the results .
6.4.7 Inductive Transducer. . As shown in Fig. 6.10, LVDT is widely used in electronic comparators, thickness measuring units, level indicators, crop testing machines and numerically controlled machines. It has fine resolution, .Sensor technologies. Distance measurement is a common task for sensors. Various kinds of sensors are used in industry which vary in their technical principles: Inductive sensors measure distance to a metal object in harsh ambient conditions. Capacitive . The following table shows a small list of mechanical transducers for measuring different quantities and responds with mechanical signal. Quantity to be Measured: Mechanical Transducer: Type of Output Signal (Mechanical) . Capacitive Thickness Transducers: Inductive Transducers: Inductive Displacement Transducers: Inductive Thickness .The definition of the capacitive transducer is to measure the displacement (how much distance it covers), pressure and other several physical quantities, these transducers are preferred. In these transducers, the capacitance between the plates is varied because of the distance between the plates, overlapping of plates, due to dielectric medium .
Figure 13.14(a) is an air cored transducer for measurement of linear displacement. Figure 13.14(b) is an iron cored coil used for the measurement of angular displacement. . Figure 13.15 shows an Inductive Transducer which works on the principle of the variation of permeability causing a change in self inductance. The iron core is surrounded .
The best example of an inductive transducer is LVDT. Please refer to this link to know about inductive transducer circuit working and its advantages and disadvantages such as LVDT (linear variable differential transformer). inductive-transducer 1). Simple Inductance. In this type of inductive transducer, a simple single coil is used as the .
The dielectric sensitivity of capacitive sensors can be exploited for use in sensing the thickness or density of non-conductive materials. Unlike capacitive sensors, inductive sensors use magnetic fields for sensing. . An inductive sensor can be mounted to measure the runout of a rotating shaft. But even if the shaft is ideal, with absolutely .of metallic plates. Wei li et al [4] presented an eddy current method for thickness measurement of metallic plates. K.Suresh et al [5] investigated a resonance method for non-magnetic and conducting sheets thickness measurement. LVDT is basically an inductive transducer most widely used for measurement of displacement [6]-[15]. The plate we want to measure its thick thickness is placed between the two sensors. The proposed measurement procedure is based on lift-offs evaluation of a bi-eddy current sensor.Inductive sensors provide high resolution measurement for even the dirtiest environments. These advantages have made inductive sensors indispensable for many machine builders, production managers, or precision metrology .
We enhance your product quality by means of the patented technology of our in-line thickness measurement device with its high-performance control algorithm for automated control of productions. . The distance between both sensors is fixed by a combined inductive sensor or adjusted by a zero cross profile. Download PDF. USMX – Ultrasonic .

The voltage sensitivity of inductive displacements transducers increases with a rising inductance. It depends on the ratio of core diameters. An optimum ratio between the central core diameter and .
Magneto-inductive sensors. mainSENSOR MDS-35/-45. mainSENSOR MDS-40-MK. mainSENSOR MDS-40-LP. Customer-specific sensors. . Sensor for precise thickness measurements. The new thicknessSENSOR opens up diverse application possibilities in terms of non-contact thickness measurement. The sensor operates with high precision and enables . An inductively coupled ultrasonic transducer system (ICTS) is a lightweight, wireless, battery-free, and low-profile (0.5mm thick) permanently installed sensor system for measuring remaining wall . So, if we multiply 12 mm by 0.5, we will end up with 6 mm as the sensing distance for a brass object. This means if we want to sense an object that is made of brass, the distance between the sensor and the object should not be more than 6 mm for this sensor to be able to sense the object.
