Valve positioner with linear potentiometer
Badger Meter’s SRD991 top-mount valve positioner is designed to mount directly to the top of a control valve with a rugged linear potentiometer. The SRD991 is designed for applications that require positioning accuracy or when greater force is required over the standard actuator such as high shutoff pressures or excess packing friction. The top-mounted SRD991 uses a linear connection, which mitigates hysteresis between the positioner and actuator by feeding back the actual position of a valve actuator for consistent flow control. The SRD991 top-mount positioner is available with a large amount of benefits including a LCD screen, protocols-HART, Profibus-PA and Found Fieldbus H1-and two levels of diagnostics. The diagnostics features can be displayed by the positioner DTM. The positioner DTM also enables a complete health report of the valve with configuration and diagnostics data.
