Strain Transmitter Protects Injection Molds
Amherst, NY (August 21, 2007) - A new strain transmitter from Kistler Instrument, Type 9238A... is designed to sense the impact of mold clamping in injection molding machines. The new transmitter protects from over clamping of the mold halves. The sensor operates in the molding machine control system to limit the force that drives the mold platens together. Thus mold damage and potential damage to mold auxiliaries is eliminated.
The instrument mounts on the moveable member supporting the mold and senses the strain which equates to clamping force. Strain impends upon the piezoelectric quartz instrument element which produces a proportional electrical charge to the built in amplifier. This technology is ultra reliable as the element generates an output from molecular like actuation eliminating material fatigue, a common shortcoming with strain gage instrumentation. The amplifier output signal easily integrates into the machine's control system. Both measuring ranges and other functions such as signal inversion and signal offset can be preset by the software. Combining the miniature amplifier with the sensor in one compact unit that mounts with a single M6 screw protects the amplifier from the rigors of routine production. OEM design approaches and retrofits are easily accomplished with the cleverly designed software.
Kistler is a worldwide supplier of precision instrumentation for the measurement of pressure, force and acceleration serving the R&D, Industrial and OEM Communities.
