- Stainless steel diaphragm
- Piezo-resistive pressure sensor
- for clean to slightly polluted liquids.
- 2-wire probe
- High accuracy
- Integrated overvoltage protection
- High electrical operating safety
The hydrostatic level probe features a diameter of only 27 mm and hence can be installed in tubes as used mainly for groundwater level measurement and deep well measurements.
The mechanically robust sensor body made of stainless steel (1.4571) and the separating diaphragm (1.4435) are held from the top on a self-supporting cable made of PUR.
The probe can be strained using a straining clamp.
The proven piezo-resistive measurement principle guarantees high long-term stability and operational reliability. Furthermore the reverse polarity protection, the short circuit resistance as well as an integrated overvoltage protection within the sensor body ensure high operating safety.
Utilising the widely used 2-wire technology, the installation costs are very low.
