Inductive proximity sensors are used for non-contact detection of metallic objects. Their operating principle is based on a coil and oscillator that creates an electromagnetic field in the close surroundings of the sensing surface. The presence of a metallic object (actuator) in the operating area...

Users of inductive proximity sensors can select from a vast array of standard types to solve almost any general purpose. sensing application. Unfortunately not all industrial sensing applications fall into the general-purpose. category. Many applications have unique requirements such as the need...

Inductive sensors and resistance welding Resistance welding is known to create electromagnetic interference at levels high enough to falsely trigger inductive proximity sensors. Inductive proximity detectors used near welding applications require special coil and core combinations to prevent false...

Inductive proximity sensors detect metal objects without touching them. Factor 1 inductive sensors have at least two coils in their design. One technique connects the first coil to an oscillator circuit while the other coil is part of an impedance circuit that controls the amplitude...

...their detection faces. Whenever a detectable object moves into the sensor's field of detection, Eddy currents build up in the target and dampen the sensor's magnetic field. This effect triggers the sensor's output. Since a current in the target is needed for detection, inductive proximity sensors are uniquely...

...for inductive proximity sensors. Sensor manufacturers address weld slag and splatter problems in numerous ways. One way is by making the sensor front cap particularly resistant to slag and splatter. The reason is most often the sensor face is directly exposed to the weld flash. Thus slag...

...and oscillation amplitudes return to normal levels. Those target materials have little effect on electromagnetic fields, so inductive proximity sensors are useless in these situations. The sensing field must change from the electromagnetic domain to the electrostatic domain; the inductive proximity sensor... suitable for a plastic target; an inductive sensor requires a metal target. In capacitive proximity sensors, the sensed object changes the dielectric constant between two plates. Sensing range is usually quoted relative to water. Because changes in capacitance take a relatively long time...

...that their specification limits are not exceeded. In practice however, even when taking the utmost care, this cannot always be permanently guaranteed. For this reason, there is a growing interest for sensors having as wide a "misuse tolerance" as possible. This is particularly valid for inductive...

...machine controls, a larger concentration of sensors can be observed. This should not, if possible, oblige the machine manufacturer to modify the mechanics just to provide space for detectors, it would be in fact illogical that the use of detectors makes the mechanics bulkier, therefore more...

  • CR4 - Thread: Capacitive Sensor Problems
    If indeed the lighting is the root-cause, installing an inductive filter lighting cover on the fixtures... These are available from several vendors on their internet websites. If lighting is not the source, look for high electrical current consuming devices/equipment and/or high static generating devices such as a computer CRT display/console within the near proximity of the sensor and relocate them as far away from the sensor as possible.
  • Refiner disc gap and wear measurement method. Final report for the period August, 1995 - January, 1999
    One short coming of the inductive proximity sensing technique is that the bridge circuit in the signal conditioning module has a strong material dependence in the latest electronics package from the vendor . Photo 2 shows the sensor diameter test fixtures used to evaluate diameter change on sensor response.
  • An Undergraduate Survey Course on Asynchronous Sequential Logic, Ladder Logic, and Fuzzy Logic
    It contains two conveyor belts, a number of solenoid-based actuators, and proximity and inductive sensors . PLCs available from practically any vendor , such as Allen Bradley, Siemens, or Omron, would suffice for this.
