...changes from a few inches to several feet. In the typical LVDT level sensor, a stainless-steel float coupled to a nonmagnetic stainless-steel rod is attached to the high-permeability armature core of the LVDT. The 4 to 20-mA loop-powered LVDT position transmitter senses the position of the core...

...current characteristic of a part with respect to the position variable. In a profiling application, either a dual- or single-element eddy current sensor is passed over the surface of the part and its position, with respect to that part is measured with a linear displacement device such as a linear...

  • Instrumentation to Enhance Advanced Test Reactor Irradiations
    Figure 6-17 presents the deviation of the indicated displacement, rela- tive to the time 0 output, as a percentage of total linear travel (which is 5 mm for all sensors ). As indicated in this figure, Vendor A LVDTs were found to be very stable through ~330 h. … period is equivalent to a displacement of ~0.004 mm rela- tive to their time 0 position .
  • EVALUATION OF LVDTS FOR USE IN ATR IRRADIATION EXPERIMENTS
    Figure 7 presents the deviation of the indicated displacement, relative to the time 0 output, as a percentage of total linear travel (which is 5 mm for all sensors ). As indicated in the figure, Vendor A LVDTs were found to be very stable through ~330 h. … that period is equivalent to a displacement of ~0.004 mm relative to their time 0 position .
  • New Sensors for the Advanced Test Reactor National Scientific User Facility
    output) as a percentage of linear travel (which is +/- 2.5 mm for all sensors ). LVDT response during long duration testing. As indicated in Fig. 8, Vendor A LVDTs were found to be superior to Vendor B LVDTs. … maximum deviation was equivalent to a displacement of ~7x10-6 m relative to their time 0 position .
  • Evaluation of Candidate Linear Variable Displacement Transducers for High Temperature Irradiations in the Advanced Test Reactor
    The use of LVDTs to measure linear displacement is a relatively mature technology. However, as discussed below, options for use in the ATR are limited when considering LVDT vendors with sensor operating histories in a nuclear reactor environment. … been used for many decades for the accurate measurement of displacement and within systems for positioning control.
  • SI-Traceable Spring Constant Calibration of Microfabricated Cantilevers for Small Force Measurement
    The AFM used in this experiment was equipped with a linear variable differ- ential transformer ( LVDT ) displacement sensor that had been calibrated interferometrically by the vendor for the Z direction. Once the AFM cantilever has been precisely posi- tioned over the appropriate location, it is then pressed against the reference cantilever.
  • North American Position Sensor Market Forecast to Grow at 7.58% CAGR Over the Period 2012-2016
    The other vendors mentioned in the report are Banner Engineering Corp., Denso Corp., Eaton Corp., Honeywell International … According to the report, the Position Sensor Market in North America is witnessing many growth drivers such as the increasing adoption of position sensors, including in the Aerospace industry.

  • New Sensors for the Advanced Test Reactor National Scientific User Facility
    For the long duration test, all four LVDTs were configured in the test fixture with cores set as close as possible to null positions . … the indicated displacement (relative to the time 0 output) as a percentage of linear travel (which is sensors ). As indicated in Fig. 8, Vendor A LVDTs were found to be superior to Vendor B LVDTs.
  • Summary report of fuel rod displacement sensor for LOFT
    Technical specifications and operat- ing environment for the required displacement sensor influenced the decision to use a linear variable differential transformer ( LVDT ) for the application. Based on development test results, five sensors were purchased from a single vendor for qualification tests. For calibrations, precise core positions depend on use of a digital stepper motor driving a rotary to …
