Abstract: A gas detector (100) includes a housing (1), a sensor in the housing and an adapter (3, 3.1). An inlet in the housing provides a fluid connection between the sensor and the environment. The sensor is configured to measure a detection variable that correlates with the concentration of a target gas to be detected. The adapter (3, 3.1) can be detachably and fluid tightly mounted on the housing. A fluid guide unit can be connected to a connection element (12, 12.1) of the adapter (3, 3.1). When the adapter (3, 3.1) is attached, an elastic filling (6, 6.1) is located between an outer shell (9, 9.1) of the adapter (3, 3.1) and the sensor. The filling (6, 6.1) is made of a cured foam. The foam includes fluorinated rubber. A channel (10, 10.1) in the filling provides a fluid connection between the connection element (12, 12.1) and the sensor.

Abstract: A photo-ionization detector (100) and a process detect an ionizable substance in a gas (G). At least two measuring cells (20.1, 20.2, 20.3) are mounted on a measuring cell carrier (10). A radiation source (4) emits ionizing electromagnetic radiation towards the measuring cell carrier (10). The gas (G) reaches at least one measuring cell (20.1, 20.2, 20.3). Ionization of the gas causes a measurable electrical property of the measuring cell (20.1, 20.2, 20.3) to be changed. Depending on the electrical property, the measuring cell (20.1, 20.2, 20.3) generates a signal. This signal correlates with the presence and optionally the concentration of ionizable substance in the gas (G). Preferably, the measuring cell carrier (10) can be rotated relative to the radiation source (4).

Abstract: A detachable belt connector system (100), for the detachable connection of belt ends (770, 775), includes a first connector element (110) with a first connection area (112) and a first belt fastening area (116) and a second connector element (120) with a second connection area (122) and a second belt fastening area (126). The first and second connection areas are configured to be connected to one another in a detachably with a positive-lock. The belt ends can be fastened at the belt fastening areas via a corresponding permanent fastening mechanism. The first belt fastening area and/or the second belt fastening area are configured such that they have a predetermined breaking region (140), by means of which an irreversible break takes place at the belt fastening area having the predetermined breaking region when a predefined limit pulling force (150) is applied at the detachable belt connector system.
