Melt probes are designed for the usage at extrusion sides. Sword shaped, conical and plane measure tips allow a good temperature recording. Accordingly to the thread melt probes can be screwed at standard holes of the extruder. It is to select between single and double thermocouple and isolated or not isolated design. The thermocouple plug is solid connected with the turned part. The sensor parts are out of own production and manufactured on ultra-modern CNC-machinery.
