3. Combined Melt Pressure Temperature Sensor Operating Instructions Combined Melt Pressure Temperature Sensor Zertifiziert nach ISO 9001 2008 Please read this instruction manual carefully before installing the transducer Measuring equipment for extruders Contents Introduction Operating range and field of application Danger areas Waste disposal Transport and storage Cleaning of the sensors Installing Uninstalling Connecting and commissioning of the DTAI Technical Data O ON fF W N 0 Dimensions 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 service technicians who will be pleased to be of assistance 2 Operating range and field of application Gneuss melt pressure transducers have exclusively been designed for the pressure monitoring of liquid doughy or pasty materials at high temperatures These must have a homogeneous constitution The application area has to be selected in such a manner that a max Differential pressure of 2 of the measuring range based on the diaphragm surface is not exceeded Any use beyond
