Advantages

• Overspill-protected, heated sensors with self cleaning effect • Universal use due to flexible measuring range • Operation and display at easily accessible mounting locations possible incl. integrated point level relay and integrated control functions

• Universally usable (free adjustable measuring range) • Unaffected by temperature layers • Free of maintenance •Remote indicator and control •Remote access via Bluetooth® 2-wire (HART®, PA, Modbus, Ethernet-APL) ±2mm/±0.08" –40 to +130°C/–40 to +266°F –1 to +3bar/–14.5 to +43psi Threads, flanges (DIN, ANSI, JIS), hygienic connections 40m/130ft
