DESCRIPTION
The SimTach A is
which provides a calibrated speed readout from a variety
of
signal sources. Its wide range
face to process signals, DC tachometers and motor
drives. An optional digital calibrator offers precise scaling
while maintaining accuracy. Easy installation and convienient switch selections make
indicator applications.

PANEL MOUNTING
Make a panel cutout as shown below (right). Affix the
adhesive gasket (for watertight
panel. Remove the panel straps and slide the unit
through the cutout.
Slide the panel straps into the
enclosure guides. Secure the unit by tightening the hex
washer head screws into the guides.
