The Expert 1400 is built for long service life in real field conditions. A ceramic diaphragm and an AISI 316L stainless steel body, along with surge resistance, make it a strong fit for demanding installations, especially where precision and approvals matter.
Key Benefits:
- Very high accuracy, long-term stability - Accuracy better than ±0.1% FS (at +10 to 30°C) and long-term stability better than ±0.1% FS per year.
- Easy integration - 2-wire 4–20 mA loop powered (10–30 VDC) output.
- Compact form factor - Slim 22 mm (.87 inch) diameter body supports well/borehole installations.
Applications
Groundwater boreholes/wells
High-accuracy measurement supports monitoring programs where small-level changes and long-term stability are important.
Drinking water basins, reservoirs, and tanks
Helps utilities maintain storage visibility and operational control with stable, repeatable level measurement.
In-fill sites and construction dewatering monitoring
Provides reliable level tracking for short-term or mobile installations where measurement confidence and ruggedness reduce rework.
Process water
Provides consistent level measurement across industrial water processes where durability and stable analog output are key.
