Application Examples of Frequency / Rate Meters & Transmitters
AC Line Frequency
Laureate frequency meters and transmitters accept line voltages
up to 250 Vac and output line frequency to 6-digit accuracy
(50.0000 or 60.0000) in a few line cycles. Fast low frequency
response is achieved by timing the period and taking its inverse.
RPM and Speed
Laureate frequency meters and transmitters can sense low-level
signals from magnetic pickups or the NPN or PNP transistor
output of active sensors. These can be powered directly by the
meter or transmitter. Output in RPM or units of speed is
achieved by mathematical scaling.
