A 7230 Series Digital probe offered control by continuously monitoring the temperature as well as the level of a settler tank.
The 7230 provides multi-variable Modbus outputs: level, interface and temperature. The sensor is unaffected by vapors, coatings, density or dielectrical variations and it requires no maintenance or re-calibration.
We installed a 7330 Pro-Stik II to monitor the tank level. The 4-20mA signal was taken back to the PLC for absolute feedback.
The 7230 Series HT Digital probe is not effected by dielectric or density changes. The magnetostrictive sensor uses a float with a specific gravity that is lower than all of the pipeline products.
