PROMPT OLT can monitor yarn tension in real time and respond quickly to problems caused by tension changes. A strain gauge sensor is used to measure the absolute thread tension of the yarn. Therefore, changes in the force acting on the sensor will cause changes in resistance and output voltage. These changes correspond to certain changes in force. These electronic signals are then further evaluated to provide immediate feedback on changes in tension.
 PROMPT OLT is designed for harsh production environments and has a splash protection function to protect the sensor from oil and cleaning agents. The integrated stainless steel guide rod protects the ceramic yarn guide and plays a role of overload protection.
