Industrial QN2SP02SDM Quartz Valve Position Sensor

Industrial QN2SP02SDM Quartz Valve Position Sensor from STONEL (StoneL) delivers direct valve-position feedback for automated process valves, built on the Quartz platform. It is rated for 125 VAC operation and uses mounting threads sized 1/2 in. and 3/4 in. NPT to fit a range of valve bodies. As part of StoneL's Quartz family of valve position transmitters, the QN2SP02SDM employs solid-state sensing to provide reliable open/closed position data for control systems, with a rugged construction designed for demanding industrial environments. Typical applications include process control in chemical plants, oil and gas facilities, and refining where valve position data feeds PLCs, DCS, or other automation networks to regulate flow and ensure safe valve operation. The Quartz platform supports integration within StoneL’s broader valve communication ecosystem, facilitating compatibility with related controllers and diagnostics across the product family.
