For harsh environments and years of reliable service, Motion Sensors' Hermetically Sealed VR Sensors are your best option. They are hermetically sealed for resistance to moisture and other atmospheric contamination . They are "The Sensible Sensor" for use in wind turbines for their ability to operate dependably in harsh environments with wide temperature extermes. These sensors are specially constructed to tolerate rigorous conditions that would cause other sensors to fail (e.g., excessive vibration, impact, and repeated thermo-cycling). (Motion Sensors now conduct vibration and other testing in-house for quality control and quick turn around !)

Product Specifications

Motion Sensors has a line of standard hermetically sealed VR sensors, which can be viewed on their website at http://www.motionsensors.com/psensor-vr.html In addition to the models specified, they specialize in providing custom 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, even for low volume applications. Motion Sensors can also provide intrinsically safe versions of VR sensors, please see additional details at http://www.motionsensors.com/vr-is.html If you do not see a sensor that meets your needs, please contact Motion Sensors and they will be happy to make a product that meets your specifications.
