Cavity pressure and temperature sensors (ø4 mm, 2000 bar, 200°C) / 6190C

The Type 6190C sensors for mold cavity pressure and temperature measurement have a front face diameter of 4 mm. The pressure acts directly on the entire front face of the sensor and is transferred to the crystal force link, which produces an electric charge (pC = picocoulomb) proportional to the pressure. This is converted by an amplifier into a voltage of 0 … 10 V, which is available at the amplifier output. The contact temperature of the melt is measured on the front side of the sensor by a thermocouple pair of Type K (NiCr-Ni). The front face of the sensor cannot be machined. The small sensor dimensions result in a quick temperature-sensing response time. The rugged combi-cable feeds both the pressure signal and the temperature signal to two connectors. The cable is screwed behind the sensor with a union nut and can be exchanged. Sensors without connectors of Type 6190CAG are available for multi-cavity molds. The charge cable can then be connected to the multi-channel connector of Types 1708 or 1710, and the two temperature conductors to the temperature amplifier of Type 2205B.
