Hydrostatic Level Probe LMP 305

The plastic submersible probe LMK 807 is designed for continous level measurement for 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: 0 ... 4 mH2O up to 0 ... 100 mH2O# — accuracy: 0.5 % FSO — diameter 35 mm — excellent long term stability — easy handling Optional Features: — SIL 2 (safety integrity level) according to IEC 61508 / IEC 61511 — different kinds of cables and elastomeres — customer specific version e.g. special pressure ranges

The detachable plastic submersible probe LMK 808 was developed for level measurement in water and wastewater. The basis of the probe is an extremely robust, almost maintenance-free capacitive ceramic sensor. For level measurement in river courses, on weir systems or in locks, great emphasis was placed on overvoltage / lightning protection. In addition, the cable can be protected against bites if necessary. The sensor head can be separated from the cable part and can therefore be replaced if necessary without time-consuming assembly work. Features: — nominal pressure: 0 ... 1 mH2O bis 0 ... 100 mH2O — accuracy: 0.35 % (opt. 0.25 %) FSO — diameter 35 mm — diaphragm ceramics Al2O3 (99.9 %) — excellent long term stability — integrated lightning protection 8 kA gas discharge tube (8/20µsec); 4 kV surge l-l/l-e according to EN61000-4-5 Optional Features: — mounting accessories — different kinds of elastomer

The separable plastic immersion probe LMK 858 was designed for level measurement in aggressive media, 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. The immersion probe is based on an extremely robust and precise pressure sensor, the membrane of which consists of a high-purity ceramic. Another special feature of the LMK 858 is the separability of the probe head and cable part. Features: — nominal pressure: 0 ... 40 cmH2O up to 0 ... 100 mH2O — accuracy: 0.35 % (opt. 0.25 %) FSO — diameter 45 mm — 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 Optional Features: — cable protection — diaphragm pure ceramic (99.9 % AI2O3)

The LMK 458 has been developed for measuring level in service and storage tanks and is as a consequence certificated for shipbuilding and offshore applications. A permissible operating temperature of up to 125 °C and the possibility to use the device in intrinsic safe areas enable to measure the pressure of various fluids under extreme conditions. The basis for the LMK 458 is a capacitive ceramic sensor element designed by BD\SENSORS, which offers a high overload resistance and medium compatibility. Features: — nominal pressure: 0 ... 40 cmH2O up to 0 ... 200 mH2O — accuracy: 0.35 % (opt. 0.1 %) FSO — diameter 39.5 mm — high overpressure capability — high long term stability — shipping approvals: ABS, BV, CCS, DNV, GL, LR Optional Features: — IS-version — diaphragm pure ceramic (99.9% AI2O3) — different housing materials (stainless steel, CuNiFe) — screw-in and flange version — accessoires
