The Trafag Differential Pressure Switch SS316 is a robust and high-precision pressure
monitoring device designed for accurate differential pressure control in demanding industrial
applications. Manufactured by Trafag AG, this pressure switch is engineered with stainless steel
SS316 wetted parts to provide excellent corrosion resistance, high reliability, and long
operational life in harsh industrial environments.
The differential pressure switch operates using a diaphragm or bellows sensing mechanism that
detects pressure differences between two process lines and activates electrical switching
contacts when the preset differential pressure value is reached. This enables reliable
monitoring, alarm generation, and automatic control of pumps, filters, compressors, and
industrial process systems.
Designed for industrial automation and process protection applications, the Trafag SS316
differential pressure switch is widely used in filtration systems, HVAC equipment, hydraulic
systems, marine applications, oil & gas industries, and chemical processing plants. Its rugged
construction, adjustable switching point, and high vibration resistance ensure dependable
operation even under challenging process conditions.
