Melt pressure sensors

Gefran Melt pressure sensors are designed to satisfy every need in plastics processing. Gefran is able to provide to its customers different Melt pressure transducers for different applications at high process temperatures, up to 1000°F.

Fluid free (I Series) IMPACT
The IMPACT series represents the innovative family of the Gefran high temperature melt pressure transducers designed on a patented fluid free technology.

 A silicon piezoresistive primary element together with a high intrinsic robustness let the IMPACT sensors to work at pressures up to 43511 PSI and to reach temperatures of 450 °F.

Oil-filled (W Series)
The oil-filled melt pressure sensors, designed by Gefran on an extensometric technology, are suitable to work at high temperature, up to 600°F, assuring a total compliance with the maximum levels of accuracy and of reliability.
Every single sensor of the W series, besides using a FDA approved filling fluid, if fully compliant with RoHS Directive.
The W serie Performance Level 'c' version is conform to the European standard EN1114-1 related to the safety requirements for extruders.

Sodium-Potassium (NaK) filled (K Series)
Between the filled-in Gefran sensors the Melt pressure transducers filled with sodium-potassium are those able to work at the highest temperatures (i.e. up to 538°C), assuring a total compliance with the maximum levels of accuracy and of reliability.

All the NaK sensors are conform to the RoHS Directive thanks to the sodium-potassium filling fluid, considered a substance “Generally Recognized As Safe“ (GRAS).

The Nak serie Performance Level 'c' version is conform to the European standard EN1114-1 related to the safety requirements for extruders.

Mercury filled (M Series)
The mercury-filled melt pressure sensors, designed by Gefran on an extensometric technology, are suitable to work at high temperature, up to 750°F, assuring a total compliance with the maximum levels of accuracy and of reliability.

The M7 serie Performance Level 'c' version is conform to the European standard EN1114-1 related to the safety requirements for extruders.
