Vibrating Reed Tachometers

The Model 2110 uses the five position dip switch plus a potentiometer to provide timebases from 0.2 to 15 seconds. This permits application where an odd number of teeth or an uneven ratio between shaft RPM and desired readout are involved. Both models are available with a wide range of accessories.

These tachometers allow a wide choice of inputs; magnetic, proximity. shaft encoder, pulse generator and surface speed adapters. Quartz crystal control assures accuracy and provides a one second time base. The Model 2100 has a five position dip switch that permits field adjustment to 1/4, 1/2, 2 and 4 second time bases to allow measurements with 240, 120, 60, 30 and 15 tooth gears. Operates on 120 or 240 VAC or 12 VDC.
