Siemens SITRANS LR260 two-wire continuous radar level transmitter for dry solids applications is easy to install and quick to configure. Its narrow horn and beam, along with Siemens Process Intelligence algorithms, ensure that the LR260 provides high accuracy of low and high levels, even with dusty solid media or filling tanks.
The LR260 is a suitable replacement for the retired SITRANS LR400 liquid level radar transmitter for applications with ranges up to 98 feet.
