Recirculations
The method used to improve the resolution of a system using a digital LDT. The On time
of a pulse width output is multiplied by a specified factor (from 1-127). This multiplication
provides more counting time for the counter in the customer’s electronics, thus improving
the resolution. The only disadvantage to higher recirculation numbers is the time needed to
process the signals.
Return (Stop) Pulse A pulse generated by the BlueOx to determine the location of the magnet assembly on the
rod end.
Rod
A stainless steel tube on which the magnet assembly travels.
RS422 Differential Differential line driver.
Start Pulse
A pulse generated by either an external device or the LDT to start a pulse sequence.
Stop Pulse (See Return Pulse)
Unipolar Power Supply
A power supply that provides a single voltage.
Volatile Position held in memory that is lost on power down.
Wire Speed
The average time it takes a pulse to travel one inch on the wire.
Zero Pulse By sending a signal to the probe at any time in the stroke a new zero point can be estab-
lished. (952 QD only)
