Description

The DIHI high-temperature melt diaphragm seal is engineered for measuring molten and high-temperature process media such as plastics, synthetic fibers, and chemicals. Built with a 316L stainless steel body and diaphragm, it withstands temperatures up to 330°C while maintaining stable and accurate pressure transmission. It is available with a rigid stem or an extended capillary design, making it ideal for applications requiring remote pressure indication. Compatible with both pressure gauges and transmitters, DIHI is widely used in plastic extrusion, chemical processing, and fiber production—offering a reliable and durable solution for extreme-temperature pressure measurement.
