Capacitance Level Transmitter By Peltek India

PELTEK 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 (such as rcc, plastic) then a reference probe is required along with main measuring probe.

Optional :GSM / GPRS based communication
