Model DPT-20 with Double-chamber case (plastic/aluminium/SS), WIKA

Possible Applications

This differential pressure transmitter is deployed in chemical processing plants and pharmaceutical manufacturing lines where aggressive cleaning agents or corrosive process media demand robust housing materials like stainless steel or specialized plastics. It is commonly integrated into secondary containment systems and filtration skids to monitor pressure drops across membrane filters, gas scrubbers, and catalytic reactors. The dual-compartment configuration isolates the field wiring from sensitive internal circuitry, which makes it particularly well-suited for high-vibration environments such as large centrifugal compressors and industrial ventilation ducting where regular maintenance cannot risk moisture or particulate ingress into the main electronics bay.
