   • Response time (4–20 mA/HART): <100 ms (transducer + electronics)

2. Output and Communication
   • Analog: Two-wire 4–20 mA with superimposed HART digital protocol
   • HART features: Universal device description, advanced diagnostics, custom tags
   • Optional FOUNDATION™ Fieldbus or PROFIBUS® PA versions (not in this model code)
   • Optional wireless HART for cable-free configuration (not in this model code)

3. Mechanical Design and Materials
   • Coplanar “C” series platform allows direct mounting of integral manifolds and flow/level modules
   • Process connection: “Alternate” coplanar flange for customer-supplied manifold or adapter
   • Wetted materials:
   – Isolating diaphragm: 316L stainless steel
   – Secondary seal: Glass-filled PTFE O-ring
   – Fill fluid: Silicone oil
   • Housing: 316 stainless steel with M20 × 1.5 conduit entry
   • Drain/vent ports: Stainless steel, factory-tested leak-tight

4. Local Display and Configuration
   • LCD display (two lines, up to eight characters per line) for process variable, units, diagnostics
   • Push-button interface for local zero, span, configuration and diagnostics without opening the cover
   • Optional graphical display (not in this model code) for multi-language menus and backlighting

5. Safety and Certification
   • Intrinsically safe certification (ATEX I 1) for hazardous locations
   • SIL 2 capable with proof testing (optional) for safety-instrumented systems
   • Optional explosion-proof, dust-ignition-proof, and worldwide approvals

6. Integrated Manifold Assembly
   • Code S5: Factory assembled to a three-valve integral manifold
   • Benefits:
   – One leak-tested assembly reduces field welding and fitting count
   – Simplifies commissioning and maintenance
   – Minimizes footprint and weight

7. Calibration and Traceability
   • Code Q4: NIST-traceable calibration certificate supplied with each transmitter
   • Code Q8: Material traceability certificate per EN 10204 3.1 B for all pressure-wetted parts

8. Additional Features and Options

   • Optional remote-seal performance report (code QZ) to quantify overall system accuracy

9. Environmental and Process Limits
   • Ambient temperature: –40 to 185 °F (–40 to 85 °C)
   • Process temperature (silicone fill): –40 to 250 °F (–40 to 121 °C) for coplanar flanges
   • Overpressure limit: 4500 psig (310 bar) with static pressure option
   • Static line pressure: 0.5 psia to 3626 psig (0.03 to 250 bar)

10. Application Benefits
    • High-accuracy gage measurement for pumps, compressors, filters, and vessels
    • Coplanar design streamlines piping and reduces installation time
    • HART diagnostics enable proactive maintenance and process optimization
    • Robust stainless-steel construction and optional sour-service materials ensure reliable operation in harsh environments
