LMK 809 Plastic Probe for Aggressive Media High Purity Ceramic Sensor accuracy according to IEC 60770: standard: 0.35 % FSO option: 0.25 % FSO Nominal pressure from 0 ... 0.4 mH2O up to 0 ... 100 mH2O Output signals Basic element of the plastic probe is the flush mounted ceramic sensor, which makes cleaning easier when solid parts of the medium deposit on it. Different cable and seal materials are available in order to achieve maximum media compatibility. 2-wire: 4 ... 20 mA 3-wire: 0 ... 10 V others on request Special characteristics ► chemical resistance high overpressure resistance especially for tank level measurement of viscous and aggressive media housing material PP-HT or PVDF The plastic submersible probe LMK 809 is designed for continuous level measurement in highly polluted and most of aggressive media. Basic element is a capacitive ceramic sensor. Preferred areas of use are Sewage waste water treatment water recycling dumpsite Aggressive media level measurement in most of acids and lyes different kinds of cables and elastomers prepared for mounting with pipe BD SENSORS GmbH BD-Sensors-Straße 1 D - 95199 Thierstein
