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.
