Abstract
Official abstract text for this publication.
The invention relates to a leak detector comprising a first sensor for detecting a gas component (helium) in a gas taken in. Because the sensor is susceptible to saturation or contamination, a second sensor is provided. The sensor is a thermal conductivity sensor. The thermal conductivity sensor has a lower detection sensitivity, yet, at a high concentration of the gas component, it does not risk being contaminated. The two sensors together allow for a large detection range, from extremely sensitive measurements to instances with high concentrations of the gas components as those which can occur with gross leaks.
First claim
Opening claim text (preview).
The invention claimed is: 1. A leak detector with a vacuum pump device through which gas is taken in, and a first sensor for detecting at least one gas component in the gas taken in, the first sensor is a saturable gas-selective sensor, wherein a second sensor is a thermal conductivity sensor and is provided to detect the thermal conductivity of the gas taken in, and a signal-receiving control device for switching the first sensor to a blind mode when the first and/or the second s…
