For Sale: Siemens SITRANS LR sensor; m/n: 7ML5430-1AB10. Almost 4 years old, never installed in a tank but was connected to a plc electronically. Has a small stress crack in housing which Siemens said will not affect operation but if moisture got in could damage the electronics. A small amount of epoxy would fix this. Retails for $1500; asking $500. Contact Steve Miller: stevem@alchemistbeer.com
