Description

This miniature version of the sensor Type 9210AA… measures the mold cavity pressure via a measuring pin. This pressure value is obtained from the force measured divided by the area of the measuring pin used. The integral single-wire cable with a very small cross-sectional area is designed to allow flexibility of mounting. With the single-wire technique, electrical shield- ing is guaranteed by the mold. It is therefore essential for the cable and connector to be integrated in the mold. The charge signal (pC = picocoulomb) produced by the force sensor is converted into a proportional output voltage in a charge amplifier or a monitor. The maximum possible output voltage at the standard amplifier is 10 V, which corresponds to the maximum pressure value depending on the measuring pin area. For multi-cavity applications the sensor Type 9210AAG without connector is used. The multichannel connectors Type 1708... and Type 1710... connect up to 4, respectively 8 sensors. Application The sensor is primarily suitable for industrial applications in optimising, monitoring and controlling injection molding of thermoplastics. The miniature sensor has been specially developed for mount- ing in multi-cavity molds where there is limited space. The sensor can be mounted directly under a mold insert by means of the lateral cable outlet. At the side, the sensor is secured via the case against rotation. Mounting is facilitated by using a measuring pin (for example a standart ejector pin). The pin can be adapted in situ to any cavity.

Calculation of sensitivity for pressure measurement When mounting the force sensor for pressure measurement, the front area of the measuring pin must considered. The nom- inal sensor sensitivity (pC/N) is converted into a corresponding pressure sensitivity using the following formula. Calculated pressure sensitivity [pC/bar] = Nominal force sensitivity [pC/N] · area of the ejector pin [mm ] · 0,1 The measuring range of the sensor must be taken into account when selecting the measuring pin. The larger the area of the measuring pin, the higher will be the force on the sensor. The following table shows the calculated sensitivity with the nominal sensitivity of Type 9210AA… and the maximum pres- sure for selecting the measuring pin. Measuring pin Sensitivity Maximum pressure Diameter [mm] [pC/bar] [bar] 1,0 -0.86 3,183 1,2 -1.24 2,211 1,4 -1.69 1,624 1,6 -2.21 1,243 1,8 -2.80 982 2,0 -3.46 796 2,2 -4.18 658 Mounting The miniature force sensor has a very finely ground front face. The contact surface of the measuring pin should also be finely machined, flat, rigid and exactly parallel. The hardened thrust washer Type 9406 supplied should be used when mounting have in a blind hole. When selecting a measuring pin, a nor - mal commercial injector pin can be used. When mounted, the sensor must not have any preload. The measuring pin must be installed with a clearance of from 0.01 to 0.03 mm. The single-wire cable must be installed completely in the mold. The connector supplied must be mounted with the single-wire cable cut to size but with its insulation intact. This is then in- serted with the mounting plate in the mold and secured. The nameplate should also be affixed alongside it giving details of the type of sensor and its sensitivity.
