Type 9221A, 9221AA..., Quartz Measuring Tongue Type 9221 for measuring cavity pres- sure in injection molding of plastics and die casting of metals. The pressure is measured indirectly via a measuring or an ejector pin. The sensor can be used with several tools by simply chan- ging it.

  • Force range 0 ... 10 kN
  • Easy repositioning in different molds
  • Exchangeable coaxial cable
  • Corrosion-resistant

Description

The cavity pressure is transmitted by a measuring or ejector pin to the convex force-sensisitive face of the sensor. The quartz element yields an electric charge proportional to the force, hence proportional to the pressure. The large measuring range of the sensor allows to use pins of any usual diameter (up to 14 mm) without danger of overload. All parts of the measuring tongue are corrosion-resistant. The exchangeable cable is screwed tight on the sensor. The Fischer connector is selflocking and splashwater-proof Application

  • in tools which already have been hardened or which do not offer enough space for a directly measuring sensor.
  • temporary equipping of a tool for measuring cavity pres- sure, e. g. for optimizing the gate profile or the machine settings. Installation The measuring tongue is inserted with the extracting tool Type 1315A into the prepared and thoroughly cleaned slot. The tongue must be positioned precisely to assure that the force is acting in the center of the sensor. The cable connector of the tongue can be fixed with the mounting plate Mat. No. 65005208 (Fig. 1).
