Description
Technical Field
The invention belongs to the technical field of tension sensors, and particularly relates to a tension sensor for a bobbin winder.
Background
Yarn tension sensors are used, for example, in winding machines which wind a yarn from an unwinding bobbin, for example a cop, to a winding bobbin (usually a cross-wound bobbin). For the quality of the wound bobbin, it is important to maintain a predetermined yarn stress or yarn tension. In order to comply with a predetermined yarn tension, it is known to adjust the yarn tension. For this purpose, the yarn tension needs to be measured with a yarn tension sensor.
When the housing of the yarn tension sensor is mounted in a working position of a winding machine or other textile machine containing a moving yarn, a tension force may occur on the housing. This tightening force is transmitted to the force sensor. The tightening force can directly influence the measurement values of the measuring bridge and thus lead to measurement errors. It is also possible that the tensioning force slightly displaces the contact between the force-transmitting element and the force sensor or a measuring bridge located on the force sensor. Measurement errors may also occur.
The conventional piezoresistive Wheatstone bridge measuring component is fixedly installed through ceramic, but the ceramic is easy to break and has a short service life.
