FAQs
1.What are the main benefits of the DPDT relay output on the FTL41-AA4A7AA2A1?
The DPDT (Double-Pole Double-Throw) relay allows the sensor to switch two independent circuits simultaneously. This means you can trigger a local alarm or control element while simultaneously sending a status signal to a central programmable logic controller (PLC) or control panel.
2.Does changing the liquid type require resetting or recalibrating the level switch?
No, the device utilizes advanced tuning fork vibration technology. The switching points remain highly stable and consistent even if the liquid density, viscosity, temperature, or exact chemical composition changes mid-process.
3.Can this specific model be installed in outdoor or washdown environments?
Yes, the sensor features a compact build with a robust process connection and an IP65-rated valve plug assembly. This construction provides reliable resistance against dust and low-pressure water spray, making it suitable for standard outdoor and industrial environments.
