A1L04B200 Wheel Pulse Transmitter


Wheel Pulse Transmitter A1L04B200 for speed measurement on moving conveyor belts and on roll surface

The BRAUN Wheel Pulse Transmitters Series A1L04 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 unit will convert this signal into a display, or analog or data signals of the speed or length.

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.

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 with the ready-to-use cable L3A25BP.
