Setra Systems introduces Model 209 variable capacitance pressure transducers for extreme environments. Model 209 is available in ranges from 1 to 10,000 psi (0.07 to 670 bar) with choice of gauge, sealed gauge, or vacuum pressure and 4-20 mA; 0.5 to 5.5 V-dc; 1 to 6 V-dc; or 0.5 to 4.5 V-dc output with ±0.25% accuracy. Units operate from an unregulated dc power source at -40 to +85°C (-40 to +185°F). With a self-contained electronics package, durable Model 209 incorporates a corrosion-resistant stainless-steel capacitance sensing element coupled with a high-level output IC-based circuit with a center-mount electrode. Transducers are free of seals or O-rings, preventing leakage and improving media compatibility with a range of gases and liquids. Various connector types are offered to suit user requirements.
