Variable Reluctance Sensors - Humbucking
 

Humbucking sensors are special dual coil versions of the MSI Premium series and feature the same materials and construction methods. These sensors offer very high resistance to electrical interference with little or no loss in signal strength. Humbucking sensors must be used with a differential amplifier to condition and isolate the signal and eliminate unwanted electrical interference. They have the ability to cancel out most of the extraneous noise that is generated by motors, pumps, overhead lines, or other electrical devices that often create signal problems.

Product Specifications

In addition to the models specified, MSI can make custom Humbucking sensors in other lengths, diameters, configurations, mounting threads (e.g., metric) as well as with different operating specifications and options like pigtail leads, NPT threads for explosion proof applications, etc. to satisfy special requirements. If you do not see a sensor that meets your needs, please contact us and we would be happy to make a product that meets your specifications.
