Cavity pressure sensors, direct measuring (ø4 mm, 2000 bar) / 6157C

This Unisens quartz sensor for cavity pressure (Type 6157C) has a front diameter of 4 mm. An O-ring seals the annular gap of <10 µm between sensor and mounting bore, and thus 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 (0 ... 10 V) in the amplifier, and is then available as an amplifier output. 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 6157C sensor is used without the single-wire connector Type 1839. For 4-channel applications, Type 6157C is mounted with the multi-channel connector of Type 1722A4, and for 8-channel applications with the multi-channel connector of Type 1722A8. This cavity pressure sensor is available with several types of connecting cables.
