Hydrostatic Level Probe LMK 809

The separable stainless steel probe LMK 358 has been designed for level measurement in waste water, waste and higher viscosity media. Basic element is a capacitive ceramic sensor. In order to facilitate stock-keeping and maintenance the transmitter head is plugged to the cable assembly with a connector and can be changed easily. Features: — nominal pressure: 0 ... 40 cmH2O up to 0 ... 100 mH2O — accuracy: 0.35 % (opt. 0.25 %) FSO — diameter 39.5 mm — cable and sensor section separable — especially for sewage, viscous and pasty media Optional Features: — IS-protection Ex ia = intrinsically safe for gas and dust — cable protection via corrugated pipe — diaphragm pure ceramic (99.9 % AI2O3) — different kinds of cable — different kinds of elastomeres

The separable plastic probe is designed for level measurement of water, waste water as well as fuels and oils. Basic element is a piezoresistive stainless steel sensor. Since the area of application is often outside a building, great emphasis was placed on overvoltage / lightning protection. In order to facilitate stock-keeping and maintenance the transmitter head is plugged to the cable assembl with a connector and can be changed easily. Features: — nominal pressure: 0 ... 1 mH2O up to 0 ... 100 mH2O — accuracy: 0,35 % (opt. 0,25 %) FSO — diameter 35 mm — cable and sensor section separable — small thermal effect — 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 Optional Features: — SIL 2 (safety integrity level) according to IEC 61508 / 61511 — different cable and elastomeres — customer specific versions

The LMK 806 with ceramic sensor and diameter from only 21 mm has been especially designed for the continuous level measurement at confined space conditions. Permissible media are waste water or and different aggressive media. Basic element of the plastic submersible probe is the flush mounted ceramic sensor, which makes cleaning easier when solid parts of the medium deposit on it. Different cable and elastomer materials are available in order to achieve maximum media compatibility. Features: — nominal pressure: from 0 ... 6 mH2O up to 0 ... 200 mH2O — accuracy: 0.5 % FSO — diameter 21 mm — excellent linearity — excellent long term stability — suitable for hydrostatic level measurement e.g. 3/4" pipes Optional Features: — different cable materials — customer specific versions, e.g. special pressure rang

The slimline probe LMK 306 with ceramic sensor has been especially designed for the continuous level measurement at confined space conditions. Permissible media are clean or slightly contaminated water and thin fluids. Different cable sheath materials are available in order to achieve maximum media compatibility. Features: — nominal pressure: 0 ... 6 mH2O up to 0 ... 200 mH2O — accuracy: 0.5 % FSO — diameter 17 mm — excellent long term stability — suitable for hydrostatic level measurement e.g. 3/4" pipes — excellent linearity Optional Features: — different cable materials — customer specific versions e.g. special pressure ranges Preferred areas of use: — level measurement at confined space conditions — ground water monitoring — depth or level measurement in wells — drinking water abstraction — level measurement in open and closed tanks
