| Function and system design | ||
| Measuring principle | An alternating voltage exists between the probes in an empty tank. As soon as the conductive liquid in the tank creates a connection between the ground probe and, for example, the maximum probe, a measurable current flows and the device switches. With level limit detection, the device switches back as soon as the liquid clears the maximum probe. With two-point control, the device does not switch back until the max and min probe is cleared. Using alternating voltage prevents corrosion of the probes and electrolytic destruction of the product. The material used for the tank walls is not important for measurement because the system is designed as a closed potential-free circuit between the probes and the electronics. There is absolutely no danger if the probes are touched during operation. | |
| Equipment architecture | probe with integrated electronic insert (compact instrument version) probe without integrated electronic insert (separate instrument version) for one, two or multiple point detection respectively, see section measuring system | |
| Input characteristics | ||
| Measured variable | resistance change between two conductors caused by the presence or absence of a conductive product. | |
| Measurement range | The measuring range is dependent on the mounting location of the probes. Rod probes can have a max. length of 4000 mm (13 ft) and rope probes up to 15000 mm (49 ft). | |
| Output characteristics | ||
| Output signal | see section electrical connection | |
