Rechner’s Capacitive Level Measurement products are based on the Three-Electrode-Priciple which allows for accurate measurement of liquid or solid materials. Systems are comprised of a measurement probe (KFS) and analysing unit (KFA) which are selected based on the needs of the application. Alternatively, a probe with an integrated analysis unit (KFX) is available.
There are two output types available, the first being analogue output which gives an current, voltage or frequency output relative to the level. The second option is to have limit value switching. This gives up to three setpoint outputs which can either be NPN or PNP Transistor or Voltage Free Change-Over Relay outputs.
There are a number of different probes and analysing units to suit a wide variety of applications. These include units with high temperature rating, stainless steel components as well as systems with IECEx certification for use in hazardous areas.
True Level – Analogue Measurement
Advantages of True Level Systems:
- Filling level measurements in containers and tubes up to approximately 5m in diameter.
- Suitable for use with non-homogenous media to due large measuring capacity.
- Probes available with temperature ratings of -70°C up to 250°C.
- Immune to Static Electricity.
- Able to be used on different materials without the need for calibration through the use of automatic compensation.
- Able to be adjusted in empty condition with the use of adjustment aids.
Per Level – Limit Value Measurement
Advantages of Per Level Systems:
- Suitable for use with high viscosity materials such as hot glue.
- Negligible influence of buildup on sensor.
- Suitable for containers of any size.
- Limit values are independent of the dieletric constant allowing for measurement of different materials.
- Able to use multiple systems without influence of one another for multiple points of measurement.
