UniSens® - One sensitivity for the complete mould means less work, less risk
Two new cavity pressure sensors from Kistler have front end diameters of only 1mm, the world's smallest, and 2.5 mm both of which can be machined up to 0.5 mm to be made flush with the cavity wall contour virtually eliminating any marking of the moulding.
Both sizes come with UniSens® uniform sensitivity to simplify installation, option of Titanium Carbo-Nitride (TiCN) coating for use with abrasive media and 2,000 bar pressure range.
The availability of Titanium Carbo-Nitride coating, rather than hard chromium, provides optimum protection against wear, ensuring longer lifetimes. The coating delivers two decisive advantages: exceptional hardness against abrasion, and resistance to corrosion by the action of chemicals making the new sensors ideal for use with glass fiber-reinforced plastics and flame-retardant materials. The front end of the coated versions cannot be machined as this would remove the protective coating. Where front end machining is essential to match the curve of the cavity the uncoated version must be specified.
Both versions have uniform sensitivity to ensure maximum deviation of ± 3% of the nominal sensitivity (2.25 pC/bar). This simplifies installation and interchangeability of sensors, as the nominal sensitivity can be used. All versions with replaceable cable are IP67 protected. Several mounting styles and cable types deliver easy and flexible integration, especially in multi cavity moulds.
The uniform sensitivity provides excellent precision which eliminates the need for sensor detection in the system. The sensitivity of these sensors remains consistently high, so users no longer have to enter values from each sensor data sheet. This also means that replacing the sensors is very straightforward and far easier to handle, especially when multi-cavity moulds are involved. Very tight tolerance ranges and ease of handling will obviously be key advantages for manufacturers of complex high-precision parts, such as high density connectors, automotive components and medical equipment.
The new, direct measuring pressure sensors deliver simple installation due to Unisens® combined with long life in challenging applications and the virtual elimination of marking on surface of the moulding. Used in combination with the Kistler ComoNeo cavity pressure monitoring system, the new sensors add another element in the search for zero rejects in the injection moulding industry.
