Description

MPS PTA-K Series Sodium-Potassium (NaK) Filled Melt Pressure Transducer

The MPS PTA-K Series uses a sodium-potassium (NaK) filled hydraulic transmission system for reliable melt pressure measurement in high-temperature processes. Available in PT-NK-0, PT-NK-1, and PT-NK-2 configurations, it is designed for plastic extrusion and applications involving high-temperature specialty polymers. The NaK fill provides a mercury-free solution.
