The RF (Radio Frequency) Admittance Level Sensor has 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 Admittance Level Switch Low Bulk Density 250°C Polyester Chips, PVC Granules, Light Chemical Powder, Flour
Extra Sturdy - XS Admittance Level Switch Medium Bulk Density 250°C Cement Storage, Sand, Coal
Heavy Duty - HD Admittance Level Switch Low to Medium Bulk Density 300°C to 1000°C Furnace, Air Quenching Chamber, Cement, Clinker Crusher, Sinter Plant (Iron Ore), Pellet Plant
High Pressure High Temperature - HPHT Admittance Level Switch Low to Medium Bulk Density Up to 650°C & Pressure Upto 25 Bar Oil Wells
Super Strong - SS Admittance Level Switch High Bulk Density 250°C Clinker Cooling, Electrostatic Precipitator (ESP Hopper), Bag Filter
Disc Probe-DP Admittance Level Switch No Density Up to 250°C & Pressure max 15 bar Powders, Pulverized Coal, Cement,Limestone,Granular Material,Rice Husk

All the above probe configurations are availble with the following products :

  1. SLA Dot Display with remotely mounted electronics upto 15m
  2. SLA Bar Display with remotely mounted electronics for upto 50m
  3. SLA Series with a split sensor and evaluation unit
