Siemens 7ML54231MC013BA1 Radar Level Transmitter

Siemens SITRANS LR200 radar level transmitter, model 7ML54231MC013BA1, is a pulse radar level transmitter designed for continuous, non‑contact measurement of liquids and slurries up to 20 m (66 ft). This LR200 variant uses a polypropylene rod as the antenna and is rated for up to 3 bar pressure and 80 °C at the antenna, making it suitable for many process tanks. The enclosure is aluminum with epoxy paint and provides multiple process connections: 2 × ½" NPT and 2 × M20 × 1.5, with additional options including 1½" NPT (taper) with integral shields of 100 mm or 250 mm, plus BSPT/BSPP variants also available with shields. The device is intended for installation in vessels and tanks requiring reliable, continuous level monitoring, aligning with the LR200 family’s non‑contact measurement approach. This specific 7ML54231MC013BA1 configuration corresponds to the polypropylene antenna variant and supports stable operation in moderate pressure/temperature environments without product contact, making it suitable for storage tanks and process vessels where accurate liquid level measurement is essential.
