Title: Innovations by Hans Trachsel in Gas Detection Technology

Introduction

Hans Trachsel is an accomplished inventor based in Uetikon, Switzerland. He has made significant contributions to the field of gas detection technology, holding a total of 2 patents. His work focuses on enhancing the performance and reliability of photoacoustic gas detectors.

Latest Patents

Trachsel's latest patents revolve around the development of advanced gas sensors. One notable invention relates to a device designed to accomplish noise reduction in a photoacoustic gas detector. This device utilizes a sound damping element and/or a background or reference microphone. A larger external volume acts as a sound damping element (SDE) and is coupled to a smaller volume through which gas diffuses. The design ensures that externally generated sound waves are adequately attenuated by the larger volume SDE without adversely affecting the diffusion of the gaseous species of interest. This is achieved by coupling the larger SDE volume to the smaller gas diffusion volume via a long and thin pressure channel. Another aspect of his invention includes a measuring system to assess the photoacoustic excitation of analyte gas, along with a reference system to measure environmental pressure waves. This system offsets outputs to reduce noise in the detector's output signal. Additionally, Trachsel has developed a device for testing the integrity of porous members, which includes a source of pressure waves and a sensor to measure signals related to pressure losses through the porous member.
