The RF (Radio Frequency) Admittance Level Sensor have been a part of the industry since 1970s. The major challenge addressed by this family of products is immunity to application media buildup on the probe, thus making level sensing more reliable.
Depending on the density of bulk solids and process temperature Sapcon Instruments offers the following construction for Rod Probe Sub-Types:
Probe Sub-Type Probe Image Application Media Density Process Temperature Typical Application
Extra Strong - ES Extra Strong Probe for low bulk density material Low Bulk Density 250 ℃ Polyester Chips
PVC granules
Light Chemical Powder
Flour
Extra Sturdy - XS Heavy Duty Probe for medium bulk density material Medium Bulk Density 250 ℃ Cement Storage
Sand
Coal
Heavy Duty - HD Heavy Duty Probe for High Temperature Low to Medium Bulk Density 300℃ to 1000℃ Furnace
