Cavity pressure sensors, direct measuring (ø4 mm, 200 bar) / 6177B

The HighSens quartz sensor for mold cavity pressure (Type 6177B) has a front diameter of 4 mm. An O-ring seals the annular gap of <10 µm between sensor and mounting bore and thereby also center-aligns the sensor in the bore. The pressure acts over the entire front of the sensor and is transmitted to the quartz measuring element, which produces a proportional electric charge (pC = Picocoulomb). This is converted into a voltage output (0 ... 10 V) from a standard charge amplifier. All parts of the sensor are corrosion resistant. The exchangeable cable is screwed to the sensor with a tight seal. The connector is self-locking and splash-proof. For multi-cavity applications, the Type 6177B sensor is used without the single-wire connector Type 1839. For 4-channel applications, Type 6177B is mounted with the Type 1722A4 multi-channel connector and for 8-channel applications, with the Type 1722A8 multi-channel connector. This sensor is available with several types of connecting cables.
