Sensor monitors mould pressure and temperature

A Kistler Instruments product story
Edited by the Engineeringtalk editorial team May 24, 2007

The Type 6189A sensor from Kistler has a front diameter of only 2.5mm and suits the injection moulding industry.

The 6189A sensor from Kistler is designed for monitoring mould cavity pressure and part surface temperature.

It has a front diameter of only 2.5mm.

The new sensor, part of the Kistler range of sensors for the injection moulding industry, is suitable for use with multi-cavity moulds producing very small parts.

The quartz pressure measuring element, sensitivity 6.5pC/bar, has two, Type K thermocouple leads fed through and welded to the front face of the sensor to achieve a rapid reaction to changes in temperature.

The Type 6189A sensor has a range of 0 to 2000bar and 0 to 200C.

The miniature connector used on the sensor can be replaced easily, if damaged.

In addition to providing important information about the mould temperature settling behaviour during production start-up, pressure and temperature monitoring can be used to control the moulding process automatically to identify the steady mould temperature state and release the parts.

This will improve productivity and reduce rejection levels, especially when moulding precision components.
