Overvoltage protection - Import export

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 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 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
