Conductivity Controls Sensitivity vs. Maximum Probe Wire Distances
Sensitivity vs. Maximum Probe Wire Distances - in feet*
Notes:
- DC on probe circuit-maximum distance between control and probe is limited to the total resistance of the wire and liquid.
- Total resistance must not exceed the sensitivity of the control.
- On controls directly connected to floats rather than probes, maximum distance is limited only to the total resistance of the wire.
- AC probe circuit has greater restrictions on maximum distance.
*Based on type MTW or THHN #14 or #16 AWG wire. Other wire size and sensing medium may reduce overall maximum distance.
