Dry-run protection for supply pumps in industrial piping systems.
FAQs
1.What are the main benefits of the short tube version probe on this model?
The short tube extension configuration (indicated by option D) elevates the sensor fork away from the immediate tank wall or process nozzle. This design prevents false triggering caused by liquid stagnation or thick buildup that often occurs directly at the vessel mounting connection.
2.How does the valve plug electrical connection improve maintenance efficiency?
The ISO4400 M16 valve plug connection allows operators to quickly disconnect and reconnect the wiring harness. This feature enables faster maintenance, instrument testing, or device swaps without needing to re-wire the internal terminal block.
3.Can the FTL41-AA4B7DA2A1 directly switch external hardware?
Yes, the integrated FEL44 electronic insert features a Double-Pole Double-Throw (DPDT) relay output. This setup allows the level switch to directly trigger independent local control components, such as visual alarms, acoustic sirens, or automatic isolation valves, without requiring an intermediate PLC card.
