The setting on delivery is 100 kandOmega;. | Probe | rod probes: compact instrument version 2 or 3 rods, separate instrument version 2, 3 or 5 rods - diameter without insulation: ?events 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. | Input signal | probes covered - A measurable current is flowing between the probes. probes uncovered - There is no measurable current flowing between the probes. | Supply voltage | Output E5 (FEW52): supply voltage 10.8 ... 45 V DC load connection: open collector; PNP switching voltage: max. 45 V Output WA (FEW54): supply voltage 20 ... 55 V DC or 20 ... 253 V AC, 50/60 Hz peak inrush current: max. 2 A, max. 400 ?µs output: two potential-free change-over contacts output N1 (FEW58): refer to datasheet of the connected switch amplifier acc. to IEC 60947-5-6 (NAMUR) | EU-Type Examination Certificate | T??V 03 ATEX 2295 | Non-repeatability | ?± 5 % at 0.1 ... 100 kandOmega; ?± 1 % at 1 ... 10 kandOmega; | Switching time | < 3 s | Switching delay | A switching delay of 2.0 s can be activated or deactivated via a DIL switch.
