• Available with single-wire technology

Description

The 9204B… sensor offers high resolution and a rugged, weld- ed case. The charge signal (pC = pico coulombs) 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 ampli- fier 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 technol- ogy 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 sensor Type 9204B... is used without the single-wire connector Typ 1839. For 4-channel applications the Sensor Type 9204B... is mounted with the Multi-Channel Connector Type 1708... and for 8-channel applications with the Multi-Channel Connector Type 1710... Application Although the mold cavity pressure in industrial applications is normally measured directly in the cavity, there are situations in which this is not possible, for example for reasons of space. The sensor is positioned under the ejector pin in the ejector plate, and measures the force curve by means of the ejector. This allows calculation of the actual mold cavity pressure.

Liability for consequential damage resulting from the use of Kistler products is excluded. Computation of sensitivity for the pressure measurement The front face of the ejector pin must be taken into account when mounting the force sensor for pressure measurement. The nominal sensor sensitivity (pC/N) is converted into a cor - responding pressure sensitivity using the following formula. Calculated pressure sensitivity [pC/bar] = Nominal force sensitivity [pC/N] · area of ejector pin [mm ] · 0,1 The measuring range of the sensor must be taken into account when choosing the ejector pins. The larger the ejector pin area the higher the force on the sensor. Force sensor Type 9204BE Indirect measuring sensor with replaceable single-wire cable. Suitable for mounting as complete module in the ejector plate. Force sensor Type 9204B0,2/0,4/0,6/0,8/sp Indirect measuring sensor with replaceable coaxial connecting cable in lengths of 0,2/0,4/0,6/0,8 m or special lengths.

The bearing surface of the ejector pin must also be finely machined, flat, rigid and exactly parallel. The sensor can be mounted with a M2,5-screw and a spring washer. Once mounted the sensor must not have any preload. A clearance of 0,03 ... 0,05 mm is recommended. When using the single-wire technology, it must be ensured that the single-wire cable is kept in the ejector plate and that the Type 1839 connector is also mounted in this plate. When installing the connector in a different plate, electrical shielding by the mold must be ensured.
