- 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.
