The WBR models added to the POSITAPE tape extension sensor product line feature an integrated pulley mounted directly onto the sensor. This is said to enable a highly flexible pullout angle of the measuring tape. With the integrated pulley, the starting angle of the measuring tape is adjustable to a broad range of measurement applications, even in areas that were previously not accessible, for example position measurement in crane outriggers. The linear cable extension position sensors of the POSITAPE series employ a stainless steel measuring tape that coils onto a precision-manufactured drum. The flexible stainless steel tape measures 10-mm wide x 0.08-mm thick and can be guided on small pulleys and also in opposite direction without impairing the service life of the measuring tape. With the pulley mounted directly onto the sensor the pullout angle can be rotated through 90º.
