Cavity Pressure Sensor

Type 6182C...

with Front ø2,5 mm
Miniaturized quartz sensor with single-wire technology for
mold cavity pressures up to 2 000 bar encountered in the
injection molding of plastics.

Description
The miniaturized quartz sensor for mold cavity pressure Type
6182C... has a 2,5 mm diameter front face. The small crosssectional area of the single-wire cable allows flexibility of installation. Shielding in the single-wire technology is pro­ ided
v
by the mold. It is therefore essential for the cable and connector to be integrated in the mold.
For multi cavity applications the sensor Type 6182C... is used
without the single-wire connector Typ 1839.
The pressure acts over the entire front of the sensor and is
transmitted to the quartz measuring element, which produces a proportional electric charge (pC = Picocoloumb). This is
c
­ onverted into a voltage 0 ... 10 V when used with a charge
amplifier.
