A system for correlating condition-indicative signals fed sequentially from a series of sensors, such as thermocouples installed in ports on the surface of a rotating kiln at various longitudinal and angular coordinates along the total length of the kiln, with the signals printout on a multipoint recorder mounted remotely from the kiln is disclosed wherein two photoelectric devices are disposed at fixed points adjacent the kiln for sensing the passage of a series of sensor-location indicator tabs mounted on and rotating with the kiln. The series of indicator tabs are spaced circumferentially about the kiln shell, preferably in respective radial plane alignment with the series of sensors, so as to produce a sequenced series of signals in response to the continuous passage of the tabs past one of the photoelectric devices, which signals are communicated from the device to the multipoint recorder to sequence the print mechanism on the receiving recorder and thus correlate the sequenced condition signals with the sensor locations. A single reset tab is also disposed on the kiln and activates the other photoelectric device which produces a recorder reset signal for every revolution of the kiln.
