Title: Innovations by Peter Christen in Gas Sensing Technology

Introduction

Peter Christen is an accomplished inventor based in Mannedorf, Switzerland. He has made significant contributions to the field of gas sensing technology, holding a total of 2 patents. His work focuses on developing systems that enhance safety and efficiency in environments where combustible gases are present.

Latest Patents

One of Christen's notable patents is a gas sensing signaling system. This system connects multiple gas sensing units to a central station via cables. It is designed to establish threshold levels that minimize false alarms while maintaining sensitivity to dangerous conditions. The central station includes timing circuits that activate upon detecting an alarm condition above a lower warning threshold. If the warning signal persists for a predetermined time, a warning signal is issued. A higher level signal triggers an alarm signal, either immediately or after a brief delay. The system also features self-holding circuitry, ensuring that once a sensing unit transmits a signal, the central station will indicate the condition until manually reset. Additionally, it can control corrective actions, such as activating ventilation equipment.

Another significant patent by Christen is a gas sensing unit designed for environments containing explosive gases. This unit is equipped with a gas sensor that operates on the principle of catalytic oxidation or uses a semiconductor gas sensor. The design includes at least two separate chambers: one that is compression-proof and houses the electronic evaluation circuit, and another that is explosion-proof, containing the gas sensor. This innovative design allows for easy exchange of the gas sensor without needing to open the compression-proof chamber, facilitating maintenance and testing.
