Hydrostatic Level Probe LMK 307

BD\SENSORS has developed the LMK 307T for continuous level and temperature measurement in water or waste water applications. The advantage: simultaneous recording of level and temperature with separate independent signal amplification. The maintenance and wiring costs are considerably reduced. In addition to classical signal processing of the level, an additional signal circuit independent of the level which converts the temperature signal into a 4 ... 20 mA analogue signal in 2-wire technology is provided. Features: — nominal pressure: from 0 ... 4 mH2O up to 0 ... 250 mH2O — nominal temperature from 0 ... 30 °C up to 0 ... 70 °C — accuracy: 0.5 % FSO — diameter 27 mm — separate output signals for pressure and temperture ranges — excellent accuracy — easy handling — low maintenance and wiring costs Optional Features: — different kinds of cables — different kinds of seal materials — customer specific versions

The plastic submersible probe LMK 809 is designed for continous level measurement in waste water or in most of aggressive media. Basic element is a capacitiv ceramic sensor. 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. Features: — nominal pressure: 0 ... 40 cmH2O up to 0 ... 100 mH2O — accuracy: 0.35 % (opt. 0.25 %) FSO — diameter 45 mm — chemical resistance — high overpressure capability — pure ceramic sensor — especially for tank level measurement of viscous and aggressive media — housing material PP-HT or PVDF — diaphragm ceramics Al2O3 (99.9 %) Optional Features: — different kinds of cable and seal materials — prepared for mounting with pipe

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
