Description

The Type 9213B… miniature sensor offers high resolution and has extremely small dimensions and a rugged, welded case. The charge signal (pC = pico coulombs) output by the force sensor is converted in the Kistler charge amplifier or in a moni- toring 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 singlewire version. With singlewire 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 transmis- sion. For multi cavity applications the sensor Type 9213B... is used without the singlewire connector Typ 1839. For 4-channel applications the Sensor Type 9213B... is mounted with the Multi-Channel Connector Type 1708... and for 8-channel ap- plications with the Multi-Channel Connector Type 1710... Application Thanks to its compactness the miniature force sensor is suit- able for dynamic and quasistatic force measurements. This is particularly useful for an application like injection molding, where space is critical and forces are high. Indirect pressure measurement is particularly suitable for molds with small cavi- ties or a large number of ejectors. 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.

Fig. 3: Force sensor for indirect measurement of mold cavity pressure behind an ejector pin in the mold. 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. The following table shows the calculated sensitivity with the nominal sensitivity of the Type 9213B... and the maximum pressure for a selection of ejector pins. Diameter ejector pin [mm] Sensivity [pC/bar] Maximum pressure [bar] 1,6 −0,88 >3 000 2 −1,38 2,5 −2,16 3 −3,11 4 −5,53 2 000 5 −8,64 1 250 Mounting The miniature force sensor has a precision ground face. The bearing surface of the ejector pin must also be finely machined, flat, rigid and exactly parallel. A hardened thrust washer must be used when mounting in a blind hole. The sensor can be mounted from below with an M2,5 screw. Once mounted the sensor must not have any preload. A clearance of 0.03mm is recommended. When using the singlewire 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.
