Abstract
A transmitter-receiver arrangement for measuring concentration of gas and/or for measuring pressure in a container headspace, wherein the transmitter-receiver arrangement defines a measuring zone accommodating the headspace, and the transmitter-receiver arrangement includes a transmitter to emit electromagnetic radiation covering a wavelength range including an absorption line of gas, a receiver of electromagnetic radiation in the wavelength range, the receiver and transmitter positioned respective to each other defining a path for the electromagnetic radiation from the transmitter to the receiver, a fixating element for fixating the transmitter-receiver arrangement to the apparatus or filling machine, an electrically controllable actuator arrangement causing at least one common shift of the transmitter and receiver, a shift of the transmitter relative to the receiver, a change in spatial orientation of the transmitter and receiver relative to the fixating element, and a change in spatial orientation of the transmitter relative to a spatial orientation of the receiver.
