Pressure probe DS(T) 22
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.
