Cavity pressure and temperature sensors (ø1 mm, 2000 bar, 200°C) / 6188A

Type 6188A sensors for mold cavity pressure and temperature have a front diameter of 1 mm. The pressure acts over the entire front of the sensor and is transmitted to the crystal measuring element, which produces a proportional electric charge (pC = Picocoulomb). This is converted into a voltage (0 ... 10 V) in the amplifier, and is then available as an amplifier output. The contact temperature of the melt is measured on the front of the sensor by one pair of thermocouples of Type K (NiCr-Ni). The sensor front cannot be machined. The small sensor dimensions result in a short response time of the temperature sensor. The rugged combi-cable feeds the pressure signal, as well as the temperature signal, to two connectors. Sensors without connectors (Type 6188AAG) are available for multi-cavity molds. The charge cable can then be connected to the multi-channel connector of Types 1708A or 1710A, and the two temperature conductors to the temperature amplifier of Type 2205B.
