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.
