Injection moulding temperature sensor is
precise
Temperature sensors provide accurate and fast reaction temperature measurement during the cooling phase of the injection moulding processes.
The new temperature sensors from Kistler Instruments have been developed to provide accurate temperature measurement during the cooling phase of the injection moulding processes With the edges of the moulding often cooling down at a rate of 100 deg C/sec, fast reaction temperature measurement is essential

A clamping force tester can be integrated with electrode cap machining and weld current checking to monitor spot welding equipment performance and maintenance.
Compact torque sensors suit many applications
Piezoelectric reaction torque sensors, having high sensitivity, extremely rigid construction and compactness, can be adapted very easily and flexibly to suit a wide variety of installations.
Kistler temperature sensors have both thermocouple elements separately fed to the sensor front where they are welded together to create a Type K thermocouple (Ni:CrN) positioned directly at the tip to measure the moulding temperature.
Even very small changes in the contact temperature due to process variations, such as changes in the melt temperature, can be monitored precisely.
Kistler temperature sensors have front diameters corresponding to the relevant pressure sensor types and are compatible with standard cavity pressure sensors.
The same temperature measurement technique is used for the combination pressure/temperature sensor Type 6290A which has a front diameter of 4mm.
Temperature sensors, used in combination with cavity pressure sensors, allow both injection phase and cooling phase of the moulding process to be monitored accurately.
