Automation Objective • Sample physical conditioning: · Temperature · Pressure · Flow • Remote flow stream selection: · Sample · Purge · Calibration • Realizable with off-the-shelf components.

CPAC Ne. SSI Example 1 Review our sensor and actuator solutions.

Flow Control • Mass Flow Controller (MFC) • Only “real” regulatory loop. • Replaces flow meter, positioner and proportional control valve. • Integral solenoid proportional control valve. • Analog: • 4 -20 ma SP & PV • Digital • Smart Features • Point-to-point serial links • Device. Net, Profibus etc.

Pressure Regulation • Dome-loaded regulator • Fixed pressure set point • Standard 1¼” gauge • Single port tube stub • Standard NPT fitting • Standard transducer • Semi downmount • Industrial NPT fitting

Temperature Control • Standard ¼” RTD probe • Single port tube stub • Standard tube fitting • Heater options • Electric • Steam

Remote Stream Selection • Semi diaphragm valve • • • 2 -port and 3 -port styles Packless, no stem seal leaks Pneumatic actuator Requires air-logic controller. Ultra High Purity Helium leak tight
