With it, the shift operator can "tour" the temperatures of 160 tubes in a little less than eleven minutes. He can stand and watch the readings as they are automatically indicated; or Speedomax will record them for later examination and for the shift log. In either case, readings are supplied in such rapid rota* tion that it h generally possible to determine the exact point at which any high or low temperature first develops, even though the condition may later spread to other points. This speed thus helps both to detect and to isolate trouble. The installation procedure is familiar to most power engineers. The power company's staff simply makes up thermocouples and attaches them to the tubes which they decide will give the most useful temperature readings. Conventional-type couples, at points outside the gas pas- sages, are of course usually included in the tASUlUl&l Couples are connected to the Speedomax equipmtitftfyj banks of 20 each, and appropriate alarms are indu'W^I Records When Desired *. V'i-yv The Speedomax automatically measures these tqpffi; tures at a rate of one every 4 seconds. Signal on for each couple, and as long as temperature rect the instrument merely indicates . . . does It can be made to record at any time, however, throwing a switch. Or if any temperature reacfiwjRjJ^ determined limit, an alarm sounds and the automatically records until switched off. Also, or banks of couples can be switched out at in7 concentrating on areas of special interest.
