? P g electronics offers a precision scalable tachometer, model pst
201. This precision pulse tachometer comprises a high resolution pg
coder, which can deliver up to 10000 pulses per revolution and a
site configurable digital indicator. A common indicator can be used
for very wide range of speeds from less than 1 rpm to several
thousand rpm. One can choose the pgcoder resolution from a table
depending upon the speed range desired. The two units mentioned
above form a useful tool to measure rotary speed in rpm or linear
speed in meter per minute or any other speed parameter with
precision. The digital display unit is site configurable and has
electro mechanical lock to avoid tempering. Upper and lower speed
thresholds can be offered to set to give output contacts. Similarly
analogue output can be given in the form of 4-20 ma. Ideal for use
in paper machines, sheet metal lines, web speed and tension control
monitoring of any form and numerous other applications where slight
changes or difference in speeds are to be registere
