The sensor boxes combine precision air pressure transducers with a sensor for relative humidity. They can be connected to the environmental modules UW-32 to UW-34 and to the LCS climate measuring station. The extraordinarily high accuracy of the air pressure measurement of ±50 Pa is achieved by a special calibration procedure during production. The sensor boxes can be ordered with different cable lengths. As a rule, the standard connection length of 3 m is sufficient, as the sensor box must be positioned directly next to the interferometer. Positioning in the same room, for example at the height of the measuring section and as far away as possible from heat sources, is sufficient.
