Pressure and Temperature Measurement • Diaphragm Seals
Low Pressure Welded Metal Diaphragm Seals
ST Series DESCRIPTION ST Series is designed to protect electronic transmitters, transducers, and low pressure gauges against process media damage. This series of seals is ideal for transmitter applications where closed systems require high sensitivity. The continuous duty design permits instrument removal or replacement while a system is in operation without causing leakage of the process media. The instrument (top flange) and process (bottom flange) are sealed with non-asbestos aramid fiber gasket. Other gasket materials available.
FEATURES
• Ideal for protecting instrumentation from process media • Ideal for process control and pipelines • Materials available for corrosive applications • Optional seal ratings to 3000 psig (207 bar)
