DANAHER INDUSTRIAL CONTROLS 4.09
The Dynapar MAXjr Tach family set the standard for low cost industrial
rate controllers. Programmable calibration factor and decimal point
allow speed to be displayed in units, such as: feet/minute, gallons/
minute, etc. Combining high accuracy measurement with alarm
capability, built-in diagnostics, large, bright LED display, simple
programming and compact size makes the MAXjr Tachs a best value.
■Calibration factor allows display in engineering units
■0.01% accurate time interval measurement
■Large, bright 0.56" high red LED display
■Full 5 digit display capability
■High and low alarm setpoints with outputs
■Sealed NEMA 4 front panel
■Programmable decimal point position
■Built-in diagnostics
The MAXjr Tach 1 Rate Indicator/Controller performs the basic rate or
speed measurement functions. The MAXjr Tach 2 provides a choice of
operating modes: rate of input A, as in the MAXjr Tach 1; ratio of two
independent inputs A and B; and time interval, which can be the period
of A or the elapsed time between inputs A (start) and B (stop).
