Built-in Reliability for the Win
Whether measuring liquid, slurry, or solids in dirty applications, these maintenance-free sensors deliver reliable performance in any environment. The SITRANS LR100 series' 80 GHz frequency operates with ample margin to overcome signal interference from condensation, turbulence, buildup, or light fluffy solids. Advanced microchip technology provides high sensitivity, detecting even weak signals. Constructed with a corrosion-resistant PVDF housing, these sensors are IP68 submersible and built for durability, ensuring reliable readings year after year.
Ensuring Safety Success
Enhance workplace safety by eliminating the need for staff to climb tanks, lean over sumps, or enter confined spaces for instrument maintenance. The SITRANS LR100 series reduces exposure to hazardous situations. By choosing these devices, you can reclaim time previously spent on fall arrest or confined space procedures. The transmitters feature zero-meter blanking distance, allowing measurement right up to the sensor to prevent costly overfilling. With 2 mm accuracy, operational safety is improved through precise measurements across the entire application range.
