LSP 05X Potentiometric Level Transmitter Wetted parts in acid-proof, stainless steel and PEEK Compact, food compatible, hygienic design 3A approved / FDA and EHEDG compliant Process temperature -20...140°C Defined empty registration LED level monitor Unaffected by strong adhesive media LSP051 Configurable measuring range Description The level measuring device LSP05X utilises the potentiometric measurement principle and can be used in all medias that have a minimum conductivity of 50 µS/cm. The LSP has automatic recognition of top/buttom mounting position. Even angled installation is possible. In a non-conductive tank such as a plastic tank a reference rod must be installed. From the low resistive measuring rod a high frequent current is fed through the media to the tank wall. The voltage between the tip of the rod and the tank wall is measured. This output voltage is proportional to the tank filling level. Please observe that a non-linear conductivity in the media will affect the accuracy of the measurement. The measurement is unaffected by temperature and adhesive media. The instrument is ideal for measurements in small wessels with tough, pasty or strong adhesive media, such as ketchup, honey, and toothpaste. The integrated electronics provide a 4...20 mA output. www.baumerprocess.com Design and specifications subject to change without notice A version with separate rod sensor and electronics is available for applications where the ambient temperature at the measuring point exceeds 60°C. Due to the high temperature limit the LSP050 is well suitable for CIP and SIP processes. The hygienic installation is guaranteed by using one of the hygienic weld-in sleeves.
