YPL Capacitance Level Transmitter is a versatile & economical mode of measuring continuous liquid Level inside a tank or open Pits. With ease of installation & various rod / flexible cable probe Versions, this transmitter is suitable for long operating range. Transmitter is classified into two versions – Sheathed probe version is suitable for conductive liquid and Un-sheathed probe version is Suitable for non-conductive liquids. In both versions probes are Available in solid rod or flexible cable rope construction. The transmitters works on capacitance technology, where tank, liquid & Measuring probe together forms a capacitor. In Conductive liquids the measuring probe is covered with a sheath material forming an Insulator. Tank along with liquid forms a reference probe & transmitter Probe becomes main probe of capacitance thus formed. Dielectric value of insulator changes with change in liquid Level & hence the value Of whole capacitance thus formed also changes. This change in capacitance value is converted into liquid Level by getting a linear current output of 4-20 mA. In case if tank is made of non- conductive material 1 (such as RCC, plastic) then a reference probe is required along with main Measuring probe.
