Product Overview
The Turck FCS-G1/2A4-NA-H1141 is a high-precision immersion flow sensor designed for liquid media applications. It employs a calorimetric measuring principle—meaning the sensor is heated and the cooling effect of the flowing liquid is used to infer the flow rate. (德尔克)
It features a G½″ process connection and is built for robust use in industrial conditions (process pressure up to 100 bar) with stainless steel housing. (德尔克)
✅ Key Features
- Measurement Principle: Calorimetric—for liquids, the sensor’s probe is heated and flow is determined by how quickly the medium cools the probe. (德尔克)
- Medium Compatibility: Designed for liquid media; oil & water ranges specified (e.g., oil: 3…300 cm/s; water: 1…150 cm/s). (Cloudinary)
- Process Connection: G 1/2″ thread. (德尔克)
- Materials & Construction: Housing and sensor material in stainless steel (1.4571 / AISI 316Ti) for durability. (德尔克)
- Electrical Connection: M12 × 1 connector, 4-wire connection to a separate signal processor (not integrated). (德尔克)
- Operating Conditions: Medium temperature range –20 °C to +80 °C. Protection class IP67. (德尔克)
- Process Pressure: Up to 100 bar. (德尔克)
- Standby / Response Times: Typical standby ~8 s; switch-on ~2 s; response time max ~12 s. (Cloudinary)
Typical Applications
- Monitoring cooling circuits in machine tools or automation lines where liquid flow must be verified.
- Ensuring flow presence in hydraulics or lubrication lines to detect failure or insufficient flow.
- Industrial process monitoring where safe, reliable flow detection in liquid media is required (oil, water, coolant).
- Automation setups where the sensor output is fed into a signal processor and then to control or alarm systems for flow-fail detection.
Why Choose the FCS-G1/2A4-NA-H1141?
Choosing this sensor gives you a robust, industrial-grade flow monitoring solution for liquids. Because the sensor uses a wear-free calorimetric principle, it offers long service life with minimal mechanical parts. Its stainless steel construction and high pressure rating make it suitable for demanding industrial environments. Plus, with sensor and signal processing separated, you have flexibility in how you deploy and monitor the system.
