Capacitive level probe DS(T) 22

for water4-20 mAModbus

Capacitive, ceramic, relative-pressure sensor for precise water level measurement in ground and surface water Robust and slim design (22 mm diameter) made of stainless steel 1.4404 (standard), 1.4539 (optional) High measuring accuracy (0.05% FS) and long-term stability (0.1%/year) Wide availability of measuring ranges (0-2 /1 /4 /5 /20 /40 /100 /200/250 /300 m) Digital (RS485: SDI-12, Modbus, SHWP) or analog output (4-20mA) Optional: Integrated temperature sensor (type DST 22) Robust, accurate and long-term stability: The DS (T) 22 fulfills the the requirements of a modern pressure sensor. The pressure membrane is easy to clean and highly resistant. The capacitive measuring principle ensures a high accuracy (0.05%) and long-term stability (0.1% / year) Uncomplicated: The DS (T) 22 can be connected to all standard data loggers and controllers (PLCs). Either analog (4-20 mA with extended ESD protection according to IEC 61000-4 part 5, 0-1 V) or digital output signals (SHWP, MODBUS, SDI-12) can be ordered. Saltwater-resistant: For special applications, e.g. in coastal areas, brackish water or landfills, the DS (T) 22 is also available in high-grade stainless steel 1.4539 form. Last but not least: In addition to the measurement of the water level, upon request, water temperature can also be recorded with a high degree of accuracy: 0.1° C. Monitoring of water level and water temperature Surface waters: rivers, canals, lakes, reservoirs, retention basins, wadis Groundwater: wells, field measurment sites, landfill and construction sites Dams and reservoirs (leachate) Tanks and shafts (filling level measurement)
