Mercury Free 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 540°C.
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.
