Thanks to an innovative tantalum coating, the sensors of the LiquiSonic range of ultrasonic concentration and density instruments withstand aggressive process fluids, such as sulfuric, hydrochloric and hydrofluoric acids at temperatures over 130°C. As a cost-effective alternative to sensors completely made of tantalum, users can rely on the stability of the coating and the accuracy of temperature and concentration measurement, says the firm. Although the coating thickness can range from 10 to 100 µm, a thickness of 30–50 µm is recommended for corrosive applications. With ATEX Eex de IIC T3, T4, T5 or T6 approved protection, the LiquiSonic sensor is suitable for use in hazardous areas. — SensoTech GmbH, Magdeburg-Barleben, Germany
Corrosives are not a problem for this concentration sensor
