Fast and precise detection of speed and material length
The BRAUN Wheel Pulse Transmitters Series A1L04 / A1L05 are perfectly designed for
measuring speed and length on moving conveyor belts, on a web or a roll surface or
similar. The wheel pulser detects its motion and transmits a pulse train to a measuring
unit. This will convert this signal into display, or analog or data signals of the speed or
length.
Installation
A rod (20 mm in diameter) crossing the surface under measurement, should support the
sensor at its end. This rod is put through the bore in the swivel head adjustable at the
end of the sensor support bar. The sensor wheels thus should rest on the surface under
measurement by the sensor‘s natural weight, and in a way to be pulled (not pushed) by
the moving surface.
Connection
By plug-in socket at the rear end. Fits our signal cables L3A. Available ready to connect
with any length to order. To connect to our portables use ready cable L3A25BP
