Cavity pressure sensors, indirect measuring (ø6 mm, 2.5 kN, 150°C) / 9223A

This miniature quartz measuring tongue of Type 9223A is suitable for measuring cavity pressure in injection molding of plastics and die casting of metals. The pressure is measured indirectly via a measuring or an ejector pin. The large measuring range of the sensor allows the use of pins of any diameter common in small molds without danger of overload. The sensor can be used with several tools by simply changing it. The cavity pressure is transmitted by a measuring or ejector pin to the convex force-sensitive face of the sensor. The quartz element yields an electric charge proportional to the force, hence proportional to the pressure.
