Siemens introduces two enhancements to radar level measurement technology

Siemens Industry Automation & Drive Technologies has introduced two industry-leading enhancements to its radar level measurement, the SITRANS LR250, to increase operational efficiency for plant operators.

The device now comes with Safety Integrity Level (SIL) 2, which complies with the IEC 61508/61511 standard for functional safety, offering industry-leading safe failure fraction and longer confirmation cycles.

To offer plants a cost-effective solution to liquid detection in aggressive environments, the SITRANS LR250 is now available with a threaded PVDF antenna, designed to withstand interaction with corrosive chemicals such as sodium hydroxide and hydrochloric acid. Its speciality plastic Kynar design is suitable for use in food and beverage, chemical and water treatment applications.

Derek Moore, product manager for Siemens Sensors & Communication, said: “As plants continue to strive for the highest levels of operational efficiency and safety, these two new advancements deliver real benefits. To be awarded the SIL 2 accreditation is a key development for safety compliance and it is FDA accredited. The PVDF antenna is a particularly exciting addition as it enables cost-effective measurement of corrosive liquids with the one device. Importantly, performance is not forfeited as the antenna is able to operate in both high and low liquid levels in even the most space-restricting environments, meaning performance and accuracy is guaranteed in every situation.”
