Guided Wave Radar
The Honeywell SmartLine® SLG 700 Guided-Wave Radar Level Transmitter uses Time Domain Reflectometry (TDR) to deliver high accuracy and stability across demanding process tank level and interface applications. Part of the SmartLine family, it shares modular design, polarity insensitivity, transmitter messaging, tamper notification, and native Experion® PKS integration with the rest of the line.
Key Benefits
- 01Accuracy ±3 mm or ±0.03% of measured distance (whichever is greater) with ±1 mm repeatability
