LMK 858 Detachable Plastic Probe Ceramic Sensor accuracy according to IEC 60770: standard: 0.35 % FSO option: 0.25 % FSO Nominal pressure from 0 ... 40 cmH2O up to 0 ... 100 mH2O Output signals 2-wire: 4 ... 20 mA others on request The immersion probe is based on an extremely robust and precise pressure sensor, the membrane of which consists of a high-purity ceramic (99.9% purity), with which even the smallest fill levels can be reliably detected. cable assembly and sensor head detachable chemical resistance housing PP-HT integrated lightning protection and increased overvoltage protection 8 kA gas discharge tube (8/20 µsec); 4 kV surge l-l/l-e according to EN61000-4-5 different kinds of cables and elastomers Another special feature of the LMK 858 is the separability of the probe head and cable part. This advantage reduces maintenance or service tasks and also simplifies storage. Preferred areas of use are Sewage waste water treatment, dumpsite, water recycling Aggressive media level measurement in most of acids and lyes The separable plastic immersion probe LMK 858 was designed for level measurement in aggressive media (acids, alkalis), desalination plants and for use in more viscous media such as sludge. Since the area of application is often outside a building, great emphasis was placed on high surge / lightning protection. cable protection (on request) BD SENSORS GmbH BD-Sensors-Straße 1 D - 95199 Thierstein
