Description

The CSIS Intrinsically-Safe Capacitance Transmitter is designed to detect the fluid levels of liquids in hazardous applications without the risk of ignition from a mixture of flammable and combustible materials in the air when a spark or heat is present. All models are equipped with durable, stainless steel enclosures and 316 stainless steel sensing probes. Output signals are available in 4-20 mA and 1-5 VDC, depending on the application. A variety of mounting sizes and probe lengths are made to order. The CSIS has suggested entity parameters to operate the sensor and is strictly used for intrinsically-safe platforms.

Principles of Operation

The metal probe rod and outer shield act as conductive plates that encompass the dielectric media within a tank. As the electric current passes from one plate to the next, the control board within the junction box serves as a transmitter. The PCB accepts input from the probe and relays an output signal. The measured output dictates the media level within the tank. LEARN MORE ABOUT CAPACITANCE TRANSMITTERS >
