Measuring equipment for extruders Melt Pressure Transducer DAIL 1. Introduction: Melt pressure transducers are precise measuring probes which obtain their measuring accuracy and long life span only if they are properly handled. These operating instructions should be studied carefully before installing the sensor, thus ensuring a trouble-free operation. Nevertheless, should you encounter any difficulties, please feel free to contact our technicians or our representatives, who will be pleased to be of assistance. 2. Operating range and field of application: Gneuss melt pressure transducers with...

Measuring equipment for extruders Melt Pressure Transducer DAIL 6. Cleaning of the sensors: In order to clean the diaphragm, the sealing surface and the process thread the sensor must have the same temperature as the plastic melting point. The diaphragm and the sealing surface can be wiped down with a soft cloth, the thread can be cleaned with a steel brush. (Do not come into contact with the diaphragm surface!) 7. Installing / Uninstalling: Installing On installation of the pressure transducer it is imperative to note that the sensor bore corresponds to the dimensions mentioned below. The fitting...

Measuring equipment for extruders Melt Pressure Transducer DAIL Uninstalling The uninstalling of the pressure transducer has to be done in a heated up condition (plastic melting point). On removal of the sensor, please take note that the diaphragm is not brought into contact with surrounding parts. It is of vital importance that the force for uninstalling the sensor must only be applied at the shaft (hexagon). Do not apply any force to the sensor head! The most common cause of failure of this kind of pressure transducers is the damage of the diaphragm during installing/uninstalling of the transducer....

Measuring equipment for extruders Melt Pressure Transducer DAIL 9. Connections and commissioning: After the pressure transducer has been installed into the line, as described in section 7, the electrical connections have to be applied according to the connections described hereafter. Gneuss pressure transducers are equipped with high quality and robust plug connections. The connecting wire should be soldered with great care as transmission errors of signals can otherwise occur. We recommend using Gneuss prefabricated connecting wires which are available ex-stock. Pressure sensors of the type...
