Abstract
Surface temperature measurements of the tubes of operating power boilers are facilitated by using ganged and preferably scannable hollow-core sapphire probes to capture infrared radiation emanating from discrete tube surface areas. By selectively overlapping the tube surface areas scanned, the greater diameter of the scanning beam in relation to the tube diameter is compensated for and individual tubes can be assessed for surface temperature. Multiplexing the outputs of many probes to a remote signal processor which also controls the scanning regimens provides systematic automated temperature readings.
