Analog Hour Meters
An analog hour meter is an electromechanical time counter that gives the elapsed operating time on a mechanical display made of rotating digit drums. It counts as long as voltage is present at the supply terminals; it is used on machines, compressors and generators to track total operating time and maintenance time. This category includes the Tense SF-48, a 7-digit, 220 V AC supply, panel-mount operating-time hour meter. Select the meter by the voltage of the control circuit it will be energized with, the cut-out dimension in the panel door and the number of digits. The mechanical display holds its last value when power is cut. An hour meter is not a timer relay; it does not switch a contact when the time elapses, it only accumulates and displays the total time.
