Water Level Sensor Wiring

Use one Fluid Level Sensor for each different fluid tank. When when working around having 2 different tanks of similar fluids it is advisable to label fuel tanks. them so they can be identified in the NMEA 2000 device list in the gauge or multi-function display. B Negative Positive Attach the positive red Connector Connector C. Well, an oscillating electrical pulsed detection of the fluid across the probes helps the probes to remain corrosion free and long lasting. Especially when this fluid sensor circuit is used as a water level sensor circuit, the probes may be required to remain immersed inside water for many occasions causing persistent oxidation of the probe metal.

Learn how to test and troubleshoot liquid level sensors, wire three-wire models, and understand operating principles for accurate level monitoring.. For more information see the "Liquid Level Float Sensor Installation Guide" section. This sensor should be wired by qualified, licensed technicians (CL wiring diagram). The 4-20mA loop powered sensor has two wires exiting the housing of the sensor. The red wire connects to signal (or + VDC), the black wire connects to - VDC.
