Level Modul for Conductive Level Probes, LNR
For conductive level switches
Output: 1 PNP
Power supply: 15 ... 36 VDC
The KOBOLD level module LNR evaluates levels in conductive level probes. The module can be mounted in the sensor housing. A 3-wire connection is used and the conductive connection between probe stem and ground is converted to a 24 V DC switching signal. The sensitivity is adjustable in 4 steps. The output signal can be evaluated and processed by a PLC.
The switching state of the output is inverted by reversing the polarity of power supply. In addition, a LED shows when the level is reached. Direct mounting to the measuring point means that no additional level device is required in the control cabinet. This means lower installation costs, minimum wiring and a high degree of noise immunity. Due to the 24 V DC supply and the active output the transducer for top mounting is specially designed for level measurement with a PLC.
