Single wire technology March 1st 2009 The increasing use of cavity pressure
monitoring for quality assurance
during the injection moulding of
small products in multi-cavity
moulds is making the installation of
the sensors more difficult. To meet
this challenge, Kistler Instruments
has applied its single wire technology
to a range of sub-miniature, indirect
cavity pressure sensors.
The sensors, mounted behind the
ejector pin, measure cavity pressure
by using the force on the pin and its
cross-sectional area. The sensors use
the same precision, piezoelectric
technology as Kistler's direct
measuring pressure sensors and have
a virtually unlimited service life at
operating temperatures of up to
200°C.
The single wire, on-site
replaceable cable can be cut to length
after installation and several cables
can be passed down a single bore
helping to simplify multi-sensor
installation. More articles from Kistler Instruments Limited: |
