Built for tougher hydrostatic level tasks, this compact well probe combines a ceramic measuring cell, corrosion-resistant construction and standard 4 to 20 mA output with flexible housing, cable and protective cap options. Higher measuring ranges and longer cable lengths expand application coverage, making it a strong choice for drinking water, seawater, corrosive media and deep wells.
The ceramic measuring cell provides stable, dependable measurements in changing conditions, supporting confident level monitoring where accuracy matters. Only 0.15% error in measured values.
Corrosion-resistant materials and IP68 protection help the transmitter perform reliably in wet, submerged and demanding installations over the long term.
A robust design and application-fit material options support long operating life and help minimize service needs, especially in hard-to-access locations.
Measuring range | Standard ranges up to 40 mH2O or 4 bar; special measuring ranges available up to 16 bar |
Output signal | 4...20 mA, 2-wire |
Measuring accuracy | Typical 0.15% |
Accessories | Cable hanger, junction box |
Certificates/approvals | Explosion-protected according to IEC Ex and ATEX; Drinking water approval; Marine approval; IP68 according to IEC 60529 |
Select ATEX and IEC Ex variants where hazardous area approval is required.
A vent pipe with integrated humidity filter in the cable provides pressure compensation and avoids condensation for stable reading over time.
Choose 316L stainless steel as standard or 904L for seawater, PE cable for standard and drinking water use, or FEP for corrosive media. Protective caps in PPE, ETFE or stainless steel help tailor the transmitter to applications.
Choose from multiple measuring ranges where the application requires it.
