商品説明The LVCN6000/7000 Series is a capacitance switch ideal for low and high level detection for both liquid and solids. The LVCN6000/7000 Series can also detect level without being in contact with the product through a sight glass. Unlike other capacitance probes, the LVCN6000/7000 series can detect LVCN6000/7000 any type of conductive, nonconductive or low dielectric materials with extremely accurate performance, almost complete immunity from build up, temperature changes or condensation. In applications with plastic or concrete tanks this series does not require an external reference. The sensor operates in a manner that is similar to a simple capacitor. A high frequency oscillator is located within the tip of the probe. When the tip of the probe comes in contact with the medium, the frequency of the oscillation reaches a preset point and the detection circuit signals the switch to change state. The LVCN6000/7000 series is a compact switch that can be made with many types of process connections, such as threaded flange or sanitary. The LVCN6000/ 7000 series is made with rigid rod or cable and both can be supplied in extended versions. The rigid rod is available in PVC or PTFE. Probes are available in 24 Vdc (LVCN7000) or 85 to 240 Vac (LVCN6000) powered versions. Note: These switches are not designed for use with mediums with high dielectrics such as mayonnaise or shampoo with high salt content.
