Level Sensor Probes for RF Admittance

Introduction

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		Low Bulk Density	250 ℃	Polyester Chips PVC granules Light Chemical Powder Flour
Extra Sturdy - XS		Medium Bulk Density	250 ℃	Cement Storage Sand Coal
Heavy Duty - HD		Low to Medium Bulk Density	300℃ to 1000℃	Furnace Air Quenching Chamber Cement Clinker Crusher Sinter Plant (Iron Ore) Pellet Plant
Super Strong - SS		High Bulk Density	250℃	Clinker Cooling Electrostatic Precipitator (ESP Hopper) Bag Filter

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

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