Rotork
A new, enhanced digital smart positioner
The new enhanced YT-3700 and YT-3750 digital smart positioners (photo) can be used for both control and on/off valve applications where diagnostics are required. The YT-3700 and YT-3750 pneumatic smart positioners employ continuous monitoring and graphic display of valve position, setpoint target over time and internal circuit board temperature over time. Valve diagnostic information to NE107 standard is provided, with HART 7 communication protocol included as standard and a display for all settings and local device interaction. Commissioning can be handled locally without the need for an additional device. — Rotork plc, Bath, U.K.
