For low pressure moulding techniques, Kistler has developed new sensors with a resolution four times higher than standard sensors and with a measurement range of 0 to 200 bar.

Low-pressure techniques such as injection-compression moulding,foaming and in-mould decorating have been gaining in importanceas methods for enhancing injection-moulding processes. Industrialapplication of these techniques, however, is more complex thanstandard processes. Mould cavity pressure measurement providespractical help for mould sampling, large-scale productionmonitoring or for quality documentation.

To meet the specialrequirements of low pressure moulding techniques, Kistler hasdeveloped new sensors with a resolution four times higher thanstandard sensors and with a measurement range of 0 to 200 bar.With front diameters of 2.5mm and 4mm, the new sensor dimensionsare equal to those of standard sensors allowing existing mouldsto be easily upgraded.

The sensors are use with single-wiretechnology and are compatible with standard cables and chargeamplifiers, allowing major savings in mould engineering andmaintenance.

The sensors with product numbers 6177AE (frontdiameter 4 mm, sensitivity 45 pC/bar) and 6178AE (2,5 mm, 10pC/bar) are available now.
