Functions
- Connection and addressing of 1 to 4 Litronic streaming sensors
- Alternatively: Connection of a bus cable for bus connection box
- Interface converter RS232 / sensor bus RS 485 integrated
- Overvoltage protection
- Current limitation at short circuit
- DIN rail mounting
Characteristics
- Parameterization and calibration via integrated software
- Different operation modes available
- Channel bundling, Filter, individual adjustments
- 2x Ethernet connection
- Modular design for easy system extension
- Mounting on standard mounting-rail TS35 for simple mounting on switch cabinet
- Indirect measuring method: Capacity determination in the high frequency stray field. This method uses the different dielectric constant (permittivity) of water and different materials (solids and liquids)
- Fully reproducible sensors: If the plant is subsequently extended with sensors or if sensors are replaced, no recalibration is necessary thanks to the built-in microprocessor.
- Multiple measuring points: Up to 4 sensors can be connected to one evaluation unit.
- Modular: If required, the FMS 3K can be expanded with further modules such as digital inputs and outputs, analogue outputs such as 0-10 V/4-20 mA, etc.
- Well stowed: The evaluation unit is mounted on a TS-35 top-hat rail and can thus be installed in the switch cabinet.
- Process control and regulation: Thanks to extensive interfaces, the moisture measurement can be integrated into process control systems and controls.
- Limit values: Maximum or minimum limits can be set using the software. Light or sound signals can be triggered if required.
- Mean value calculator: The FMS 3K receives the signals from the sensors and can output already averaged values to a higher-level control if required.
- Software: The Liebherr FMS 3K software integrated in the system is available for visualization, configuration, measured value recording and calibration.
