Sensors for every parameter
Every sensor below connects to HydroLynx transmitters and packaged stations — grouped here by what it measures, with the model number along for the ride.
Water level
| Sensor | Model | Key facts |
|---|---|---|
| Submersible pressure transducer kit | 5050LL-PTK | Vented cable (40 ft standard, extensions available); ranges 0–5 to 0–300 PSIG; accuracy ±0.10 / 0.25 / 0.50 / 1.0% FSO — specify range and accuracy per site |
| Wireless SDI-12 level link | 5390WL | Spread-spectrum radio pair when cabling the sensor to the station is impractical |
