Kistler has announced the North American market introduction of its Type 6188A miniature combined pressure and temperature sensor, designed to measure both cavity and contact pressures and temperatures at the same point within the mold, supporting a variety of plastics injection molding and related quality assurance applications.
Featuring diaphragm-free design with a flat front diameter measuring of one millimeter, the Type 6188A incorporates a piezoelectric pressure sensor for cavity curve pressure measurements of up to 2000 bar with an integrated series of Type K thermocouples, facilitating melt direct contact temperature measurements of up to +450 degrees C at the front of the sensor.
The compact and flat front design allows simultaneous and rapid response to temperature changes. The pressure acts over the entire front of the sensor and is transmitted to the piezoelectric crystal-sensing element, producing a proportional electric charge. The charge is then converted into a 0-10V voltage and available as an amplifier output. Mounting dimensions of the Kistler Type 6188A are directly compatible with the company's Type 6183A pressure sensor, allowing to be used as a drop-in replacement for applications in which temperature measurements may also be required.
The charge cable can be connected to Kistler multi-channel connector Types 1708A or 1710A, as well as the two temperature conductors to the Type 2205A temperature amplifier.
