Level limit switch Series CN 4000 Technical Information / Instruction manual Capacitive level limit switch for level monitoring in all types of containers and silos. The Capanivo detects the capacitance around its probe. Due to the active shield technology it has an increased insensitivity to material buildup on the probe. It can be used with powdery and granulated bulk materials with a dielectric constant of min. 1.6 The measurement is nearly independent from the influence of the silo wall. Therefore factory provided precalibration allows measurement of most applications without...

Level limit switch Series CN 4000 Technical Information / Instruction manual General Safety Instructions Process pressure Improper installation may result in loss of process pressure. Chemical resistance against the medium Materials of construction are chosen based on their chemical compatibility (or inertness) for general purposes. For exposure to specific environments, check with chemical compatibility charts before installing. Fastening of the threaded process connection Mounting torque for the thread may not exceed 40 Nm (metal thread)/ 20 Nm (plastic thread). Use a open-end wrench. Do...
