Electromagnetic level sensor L series

TDR-guided wave radarfor liquidsbulk solids

Device for level measurement in liquids, Radar measuring device with Bluetooth® wireless technology, Measuring range up to 12 m in fluids, Process temperature up to 60 °C (140 °F), Process pressure up to 3 bar (43 psi), Accuracy up to ± 5 mm, Commissioning, operation and maintenance via P+F Level app The system is based on the reflection of an electromagnetic pulse that is directed on a sensor rod/ cable and reflected by filling material. The electronics integrated into the sensor determines the filling state from the echo time of the pulse and shows this in the display. The electromagnetic pulse is sent out, reflected on the filling material and received again. The echo time of the pulse is proportional to the distance from the surface of the medium. The measurement procedure and the accuracy of the measurement are independent of pressure, temperature, vapor, dust, foam, viscosity, conductivity and pH value. Operation mode This continuous level measurement for liquids and bulk solids is based on the propagation time measurement of microwave pulses according to the principle of time domain reflectometry (TDR), which are guided along a rod or a rope.
