Comment concerning bits 5 + 13
USW transducer rods require a certain recovery time between two measurements to allow the ultrasonic wave to
fade. Otherwise there is a risk of interfering with the next measurement (especially when the rod has more than
1 magnet).
Depending on the setting, the module waits at least 2 or 3 times the runtime of the ultrasonic wave for the measure-
ment rod (default = 3x). In the standard function module, the next measurement is then triggered synchronously
with the next X2XLink cycle.
The runtime measurement is based on the settings for the rod length (plus a safety margin of 100mm) and the
ultrasonic speed:
•
USW runtime = (rod 100mm) / ultrasonic speed.
For their rods, BALLUFF recommends a recovery time equal to 3 times the maximum runtime of the ultrasonic
wave for the measurement rod. This is the default setting for the module.
The setting can be switched to 2 times the runtime if the measurement rate is otherwise too slow. This may only
be done after consulting the manufacturer of the transducer rods!
