Turck FCS-N1-2A4P-LIX-H1141-D037 Flow Monitoring Sensor

The TURCK FCS-N1 2A4P-LIX-H1141 Flow Monitoring Sensor is an inline immersion-type device with an integrated processor for precise liquid-flow verification in industrial automation. It uses calorimetric (thermal-dispersion) sensing to monitor liquids and supports water and compatible industrial fluids, with a 1/2" NPT process connection and an M12×1 electrical connector, delivering a 4–20 mA analog output from a 19.2–28.8 VDC supply. The sensor body is stainless steel (1.4571/316Ti) with a PBT housing and is rated IP65/IP67 depending on configuration, operating from -20 to +80°C (medium dependent). Typical flow ranges are about 1–150 cm/s for water and 3–300 cm/s for oil, with a response time of roughly 2–15 seconds (application dependent) and a potentiometer-adjusted LED for flow-status indication. Installable inline or in immersion configurations, this TURCK part is commonly used in cooling circuits, lubrication systems, hydraulic units, chemical dosing, and general-purpose machinery requiring inline flow verification and protection against flow loss or dry-run. Common replacements include TURCK FCS-N1 2A4P-ARX-B3141, TURCK FCS-N1 2A4P-AP8X-H1141, and IFM SI5000 Flow Monitoring Sensor.
