Cavity pressure sensors, indirect measuring (ø6 mm, 2.5 kN, 200°C) / 9211B

The Type 9211B miniature sensor offers high resolution and has extremely small dimensions, as well as a rugged, welded case. The charge signal (pC = Picocoulomb) output by the force sensor is converted in the Kistler charge amplifier or in a monitoring unit into a proportional output voltage that is largely independent of the length of the sensor cable. The maximum possible output voltage from the standard amplifier is 10 V. In the most sensitive range this gives 1 N/V. The replaceable cables allow a wide choice of connecting cables, including the single-wire version. With single-wire technology, an individual cable is shortened to the required length and connected to the connector using the proven cut and grip technique. With this arrangement, the mold serves as a shield for signal transmission. For multi-cavity applications, the sensors of Type 9211B are used without the Type 1839 single-wire connector. For 4-channel applications, Type 9211B is mounted with the Type 1708 multi-channel connector, and for 8-channel applications with the Type 1710 multi-channel connector.
