Thermo couple connection PCA 0S 302 CLL Thermocouple Heater connection PCA 35 302 CLL Sensor heating Measuring equipment for extruders qneul3 a 9 Sensor Heating The pressure transducer DAlpremium is a high efficient sensor with integrated thermocouple and integrated heating element During the production process the thermocouple can be used as control measurement at any time The integrated heating serves to protect the sensor from damage to the membrane when processing problematic plastic melts e g polycarbonate since these contract very much when cooling down In the production process it is sufficient to set the nominal value of the temperature control approx 30 50 C below the melt temperature By switching on the heating the front part of the sensor incl membrane can be adjusted to such a temperature that the melt in the membrane area remains viscous Further the heating can be used to help to remove the sensor out of a cold machine For this it is normally sufficient to heat up the sensor for approx 15 to 30 minutes depending on the temperature Attention The sensor heating must always be controlled by the integrated thermocouple The sensor should only be heated up when being installed otherwise the heating element might be damaged During the heating process the temperature level in the whole sensor and drilling area can be very high After having installed the pressure transducer in the li
