Water Level Sensors

6521 Capacitive Water Depth Probes

These water depth probes are designed for high resolution measurement of shallow fresh or salt water. With minimal drift they use the different dielectric characteristics of water and air to measure water depths. The probes are calibrated to standard ranges of 0.5, 1 & 2 meters with an accuracy of 1% full scale and 0-2.55 VDC output. Each model contains integrated electronics and offset and gain adjustments. The probe can be disassembled for cleaning and visual verification of readings can easily be done. Salt water and high ionic water do not affect the accuracy of this probe. This probe is not designed for measuring non-ionic liquids such as hydrocarbons (e.g., petroleum). Specifications
