Features & Benefits
- Trouble-free performance in demanding applications is ensured by the shielded, dual-element, non-contact, magneto-resistive position sensor and temperature- compensated, dual-poppet pneumatic relay
- The rugged, modular design provides protection from dirt and water ingress (IP-66), impact and vibration
- One-button setup automatically configures the zero, span and gain of the positioner for most valves in less than 60 seconds
- Five on-board pressure sensors that enable operators to identify and assess the severity of developing problems so action can be taken before a critical event
- Broad application versatility with industry-leading communication technologies, including analog, HART, Foundation Fieldbus, 4-20mA or discrete I/O signals
- Optional module to remotely locate the positioner from the control valve
- Intrinsically safe, non-incendive and explosion-proof design from -52°C to 85°C (-62°F to 185°F) ensures safe, reliable operation in hazardous conditions
- Up to 80% more air capacity with minimal air consumption is made possible by the double-poppet technology
