Two-wire 80 GHz FMCW compact radar level transmitter for continuous level monitoring of liquids, slurries, and solids in ranges up to 49.2 feet (15 meters) with a zero blanking distance. 8° beam angle. Hermetically sealed PVDF enclosure and antenna. 4-20 mA output plus HART communications standard. Optional Bluetooth communications for configuration. Good for process temperatures to 176°F (80°C), pressures to 43.5 PSIG, and media with dielectric constant greater than 1.6.

Siemens SITRANS LR110 is a loop-powered W-band FMCW radar level transmitter in a hermetically sealed chemical-resistant PVDF enclosure for years of trouble-free reliable measurement. It comes standard with 4-20 mA output and HART communications. The LR110 has a zero blanking distance for accurate inventory management, and can even measure through plastic vessel tops.

Standard HART 7.0 communications makes the LR110 compatible with SIMATIC PDM software for remote configuration and diagnostics on your PC. When ordered with Bluetooth enabled, the LR110 is easy to configure, troubleshoot, and monitor via Siemens SITRANS Mobile IQ application on your smart device. The app is free, and available for Android, Apple, and Windows devices.

The SITRANS LR110 is compatible with the same Siemens mounting accessories used on Echomax ultrasonic transducers, including Easy Aimers for accurate positioning at angles for solids level measurement, and FMS series mounting kits and brackets for quick installation on liquids applications.

Help is an image away. Use your phone camera to snap a picture of the QR code on the transmitter to get instant access to user manual, certificates, serial number, and installation drawings. (Smart phones with IOS 11 or later and Android 8 or later can scan QR codes without an app. Older phones will need a QR code app installed. Search your app store for Free QR Code Reader)
