XPT Series Explosion Proof Melt Pressure Transmitter
Introduction
DWEL XPT Series are explosion-proof melt pressure transmitters with 4~20 mA output and HART protocol, specifically designed for use in hazardous environments. Constructed with a full stainless steel welded structure, this series offers both thread and flange installation options. The use of high-performance core components ensures exceptional measurement accuracy and reliability. The XPT Series is widely utilized for melt pressure control in high-precision polymer extrusion equipment, production lines, and laboratory instruments. It serves as an ideal replacement for Dynisco, Gefran, and Graeff systems.
