SG1000D - Valve/Damper Position Monitor - 1

SG1000D Product Information Description Electro-Sensors SG1000D Valve Position Monitor is a complete position monitoring system housed in a compact and rugged explosionproof NEMA 4X enclosure. It is an encoder-based position sensor providing a 4-20 mA output and is used to measure a rotary process such as a valve position having a clockwise or counter-clockwise rotary movement. The SG1000D works on rotary processes having a full-scale sweep as small as 15 degrees (fully-closed to fully-open), up through those having a full-scale sweep as large as 359 degrees. Principle of Operation The SG1000D has two modes: calibration and normal operating. After installation, a simple calibration procedure is used to program the SG1000D with the encoder values corresponding to the valve’s fully-closed and fully-open position limits. Once programmed, the SG1000D outputs a 4 mA DC signal when the valve is in the fully-closed position, and outputs a 20 mA DC signal when the valve is in the fully-open position. When the valve is at any mid-span position (between fully-closed and fully-open) the SG1000D outputs a signal that is proportionally between 4 and 20 mA.
