Product Advantage
· This sensor module excels in protection, with IP66/IP68 ratings. IP66 resists powerful water jets, while IP68 allows submersion, and it fully blocks dust, ideal for harsh outdoor and industrial settings.
· It's user-friendly with intelligent plug-and-play, easily integrated without complex setup. Calibration via Safegas PC software simplifies replacement and maintenance for optimal performance.
· A standard splash guard protects it in outdoor or water-splash environments. Weighing only 1 kg and paired with a standard mounting bracket, installation is quick and hassle-free.
· Connectivity is versatile, with standard 4-20 mA analog and RS485 Modbus outputs, plus optional Hart and 2-wire outputs for broad system compatibility.
· It has 3 optional relays for low/high/fault alarms, enabling rapid issue detection. Magnetic and remote control offer flexible parameter adjustment, making it suitable for diverse applications.
