AMETEK RPM sensors are made with simple, small flange mounts. As an added benefit, the flange mounts can be spring loaded to accommodate thermal expansion, which eliminates the need to install shims for signal requirements. Our speed sensors are qualified with samarium cobalt magnets, permeable nickel-alloy cores, and high temperature insulation copper wire. All hermetically sealed enclosures are assembled with proprietary strain relief methods and high temperature potting. Of course, all sensors are tested 100% of the time.
