Shielded dual‑element, non‑contact magneto‑resistive sensor and a temperature‑compensated single‑acting and dual‑acting pneumatic design ensure stable performance. Rugged IP66 construction resists dirt, water, impact and vibration.
Easy configuration and calibration
One‑button quick calibration automatically sets zero, span and gain, simplifying commissioning in under 60 seconds.
Predictive diagnostics
Five onboard pressure sensors and ValveSight DTM enable early detection of developing issues so operators can act before failures occur.
Application versatility
Supports analog, HART, Foundation Fieldbus, 4-20 mA and discrete I/O, with an optional remote‑mount module. Compatible with a wide range of valves and actuator types.
