Hey Bruce!
Unfortunately we do not carry the Catcon MicroPulse Holding Tank Sensor #511789 and it looks like that part is no longer available from other suppliers. If your sensor has failed, it may be time to upgrade your tank monitoring system. I recommend a SeeLevel system, which replaces the old Catcon sensors with externally mounted sender strips and a new display panel. Many Airstream owners have gone this route since the Catcon components are no longer supported. The best way to start would be with the SeeLeveL RV Holding Tank Monitoring System - Fresh, Gray, Black, Propane # SE59VR and then you can add additional sensors like SeeLeveL Sensor for RV Holding Tank Monitor # SE88VR for other locations that you may need to monitor.
What happened to the sensor that you currently have? What model of RV or trailer do you have?
