Fluid free (I Series)

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 3000 bar and to reach temperatures of 350 °C.
The whole IMPACT series is conform to the RoHS Directive and in the PL “c” version is compliant with the European norm EN1114-1 related to the safety requirements for the extruder

 

I3 Melt Pressure Transmitters – mV/V Output IE Melt pressure transmitters – Output 4…20mA IN Melt pressure transmitters – Voltage Output
I7 Impact series PLc version (Voltage Output) IX Melt pressure transmitters – potentially explosive atmospheres

 

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.
