SITRANS LR250 with threaded PVDF antenna is a 2-wire, 25 GHz pulse radar level transmitter for continuous monitoring of liquids and slurries in storage and process vessels including corrosives or aggresive materials, to a range of 10 m (32.8 ft).
SITRANS LR250 includes a graphical local user interface (LUI) that improves setup and operation by including an intuitive
Quick Start Wizard, and echo profile displays for diagnostic support. Startup is easy using the Quick Start wizard with a few parameters required for basic operation.
The 25 GHz frequency creates a narrow, focused beam allowing for smaller antenna options and decreasing sensitivity to obstructions.
SITRANS LR250’s unique design allows safe and simple programming using the Intrinsically Safe handheld programmer without having to open the instrument’s lid.
SITRANS LR250 measures superbly in small vessels and in tanks/vessels up to 10 m (32 ft) on materials with dk > 3.
Key Applications: liquid bulk storage tanks, process vessels with agitators, vaporous liquids, temperatures to +80 °C (+176 °F), corrosive and aggressive materials, media with dielectric (dk) ≥ 3 (application dependent) and applications requiring functional safety
