Abstract
A radiation detector for a non-dispersive infrared gas analyzer has two detector chambers, which are surrounded by a housing and separated by a separating element permeable to infrared radiation and impermeable to gas and which can be filled with a radiation-absorbing measurement gas. A receiving element, which has a measuring system fastened therein and including a flow- or pressure-sensitive sensor, can be attached to a contact surface on an outer face of the housing. Each detector chamber is pneumatically connected to the measuring system by a channel, which extends in the housing and is open to gas. The housing of the radiation detector is modularly constructed and includes a base element, which encloses the channel, the separating element, and the measuring system fastened in the receiving element, and a first and a second outer element, each of which can be connected to the base element and surrounds a detector chamber. The outer elements have openings, which lie in the beam path of the infrared radiation and are sealed in a gas-tight manner by a radiation-permeable window. The receiving element and the first and the second outer elements are joined to the base element.
