Title: The Innovations of Carl F Klein

Introduction

Carl F Klein is a notable inventor based in New Berlin, WI (US), recognized for his contributions to the field of sensor technology. With a total of 7 patents to his name, Klein has made significant advancements in the development of humidity and pressure sensors.

Latest Patents

Among his latest innovations is the capacitance humidity sensor. This device features a film core that is in contact with a pair of conductive layers bonded to opposite faces of the core. The core is constructed from a polyimide that has a dielectric constant which varies substantially linearly with humidity. This polyimide includes at least one ether linkage in the dianhydride portion, and may also contain ether linkages in the diamine portion and/or fluorine atoms in either or both portions. Another significant invention is the elastomer type low pressure sensor. This sensor comprises top and bottom mounting plates that support a pair of electrode layers. The first electrode layer is positioned on the upper surface of a dielectric disc, while the second layer is located beneath the disc and includes a conductive elastomeric layer overlying an elastomeric support layer. The preferred embodiment utilizes a silicone elastomer, with the conductive layer formed by mixing a conductive carbon powder with the silicone. This sensor is particularly effective in detecting pressure changes in a low range, specifically from 0-1 inch of water, and features a prestrained elastomeric layer for temperature compensation.
